to after it is recharged using solar energy and with that you are up to date is coming up next sell don't commentary takes us to the volcanic life full region in germany. how many kids and the tenants, thanks so much for watching dw, the, can you hear me? we are all set. we are watching to see we all need to bring you the story behind the new your own about come by as information for free might do to name the volcanic i sold a landscape forged and fire shaped fine for some elemental forces,

deep underground, huge glowing chunks, of rock ash that covered everything in minutes and foamed a one of a kind landscape. the volcanoes fell silent some 10000 years ago, but they're only sleeping, the ease, something brewing deep below the surface of the eiffel. how great is the danger that the volcanoes will roll back to life the, the, the in the east, if the volcanic eiffel near under. now, the forces looking benita, you showed themselves the

cold water goes up the highest in the world. the every 2 hours the water jet erupt reaching up to 60 meters in. yeah. the going so, leaks explains mineralogy, thorsten lum, that's the fuzzy that's you'll see like a 0 stage guys, a rupture needs, you knew i thought, just as each volcanic eruption is you name. i thought that the russian unleashes powerful volcanic forces deep beneath the full as carbon dioxide from the fluid. magma meets the ground water. more and more, c, o 2 bubbles, collect 350 meters below the surface. when it finally erupt, the entire wars

a column is propelled upward. yes, this one does the bonds in it, but it's gone. yeah. you can really see and feel the whole volcanic process. obviously somebody helps you understand the pressure and power behind it and it'll shoot another volcano, erupt in the iphone and binds you and i think you don't put tunnels present the but when will that happen? the volcanoes of the life will, will low source extinct. now we know that only domains deep underground the colder and is still bubbling the, the traces of the last incident of a still clearly visible today. at

1st glance, lake last is a tranquil body of water. but it was created by the most powerful volcanic eruption in recent central european geological history. 13000 years ago, the it's traces can be found on the nearby. vien gets big funds, the amended, the geologist goes to huffman and phone university. the will is a window into the distant past, the launcher for that's a 1000 john's 13000 years ago. this landscape didn't look fundamentally different from today. and then suddenly there was this explosion, 200 hurled ash and trucks some 40 to 50 kilometers into the atmosphere. the, the mass either option lasted several weeks as 1000 degrees celsius magma, mesa,

ground water reservoir. the of the mountain top above was blown off by an explosion and steam as a huge column of ash with catapulted columbus is up into the at the other one is these are at some point this column collapsed and red hot ash rushed through the landscape along the valleys and through the brother valley, for instance, when it's reached the rhine river, which already existed fact then cut the river off. the ashen debris swept over every thing and left behind a blanket, several meters deep, th, and stepped on. it's for the funds of what kind of schools i'm just all stone.

describe this one kind of corruption, tom designed and created a recivore around what is known if you today is the largest dominance at some point that broke on the hunters and others settled in the area experience to catastrophes and one lifetime would come. oh schools. first slopes and i and i felt kind of corruption and then a gigantic quarter search that went to all the way down the ryan valley into today's netherlands. the as the blue products presumed on the list of all kind of explosions. and i thought it was more an explosion than interruption. this explosion, 13000 years ago, left us traces quote, and you can see them on the wall here. as for us, these are, this is like a history book. and we can study at the centrally read had this volcanic explosion happened to cut off each single layer is like a high resolution snapshots of an individual phase of the russian hill. to

the postman regularly leads groups of scientists through here the layers of the will reveal the stages of the volcanic eruption. it doesn't say english this year, no matter why. so what's crazy is that such in there usually shows several tens of thousands of years or 15 pounds. even up here, we have a 13 meter cross section that represents a few weeks at the most. this is just a few minutes. this single there is a collapse in cloud november's or any other stand o c. and if i pull the stone notes, this is i'm going to construct not, and sarah and we and a we night with a red, blue mineral expelled from the mcmahon. or the full is one of the most important sites for routine the weld. okay. yeah. let me know at the moment if you look at it's under a magnifying glass,

it's really beautiful. levine gets bad vanities punch of the unesco volcanic eiffel g or punk hoffman, and he's team and developing an app to allow virtual travel through the volcanic landscape. everything is precisely scanned and measured the use parking tom. i assume we using the volcanic eiffel jewel park as a reference model as the very 1st jewel park in germany that offers the completely digital turning package at all points of interest. and this park can be viewed the desktop app. the app works with super precise satellite data, much more exact than basic navigation or hiking apps, the $100.00. again, it is a bunch of the money and we want to map the while back there and 3 d doctor up to

do this. you need a lot of photos on the right image processing software. if the drone can get close enough, you can get a good 3 d image comes on the data one of the the drone can also reach sections of the will that otherwise difficult to access the, the cameras scans at high resolution. so the computer that can later generate a detailed image the, the various layers in the world are especially interested and they consist mainly of pumice and tough interspersed with rock fragments drank, stopped by the volcanic eruption, the aspect funds. and

the thing it's backbone shows all the settlements, this fall kind of corruption on earth. and it's been geologically proven that there were different interruption phases. you have to imagine it's not like an exploding powder cake, but like several atomic bombs on it. and that's how powerful the home them so dentist, a lot of the big i know it's always close as long as the so what i'm the punished weed country without a fresh eruption, only class or other volcanic structures here in the life of us. and we can only hope that would be enough warning by the for example in the form of earthquakes warms one that we don't want to paint to har. scenario bush of what happened. 13000 years ago happened again today in a densely populated region like the rhineland. that's the truth would be catastrophic island. serious type of safari, the large cities like phone

industrial plants and refineries. the rhineland chemical belt, cologne, with mold and a 1000000 people. how can the region possibly protect itself from such a natural disaster? the federal academy for civil protection and disaster assistance. b, a b k in the valley generates scenarios because such disasters. professor klaus right you to is researching possible consequences of a fresh interruption of the lake lock volcano to the to on. so i think even disabled it would be a very high interruption. collins, i know the ambulance would be closed off immediately because a landing simply would the possible good. so then you'd have to see how far and how quickly the rushing cloud spreads, depending on the wind direction to move into the

league of class and the phone soon, we'd have to consider whether verbs was still usable with a critical infrastructure like trains and the power grid still worked. 20 certain vehicles may be able to drive on the free ways to evacuate people's a book, but then things would get difficult. there are no other escape routes as you can exist in the problem is that in strongly con to landscapes like the valley or he in the eiffel people have settled in the valleys and so there are only 2 ways out and forwards and backwards. there is no other option. that's why the host to come forward until the sign has been sent to the dispute. you must be losing the strength of also depending on where we uh, they will probably be casualties as well for that. so when do you do, hospital is must be prepared for this specific types of injuries that volcanic

eruptions can cause. cotton was especially bones or stuff. so they have to have dedicated burn unit. but they also need specialized units for the se amputations and emergency surgical procedures. if that would be necessary after enough quick via the businesses, unless he does nobody the that is it even possible to prepare for such a disaster? the people who humans play in order for evacuation plans or rules of conduct, what people should do in a specific situation. that's difficult, right now. there are no plans in place like that. that may be a mistake, but i don't think it's absolutely necessary yet. unlike with flooding, volcanic eruption allows more response time because it's less me insight. volcanic eruptions come with ample warning in the form of trim is and gas emissions

. at lake law, it's easy to forget that the ground below has still not settled. the old vocab and crate to is a unique natural paradise the but at the lake's eastern show, there is still signs of volcanic activity, mo, fence carbon dioxide bubbling up through the war. so the nearby, the jersey would spill to study and recreation home. so young monk c, 1970, when 8 of them died, inexplicably gas emissions from the lake. so what blamed the the young man with buried on the grounds of today's maria last abbey. in the crypt

under one of the smaller chapels with the monks really a 60 a to it has never been confirmed. the professor hoffman and his team of geologist, the lake is of great interest the most fits are important to better understand volcanic activity in the eiffel and to observe any changes the viewers and shop cliff. it's interesting to me to you, scientist. the system affects show that there is still a volcanic activity here, so you start saying it's not only ever molten rock that comes out of the ground just involved in the it's mostly gas costs. and this is why the amount of escaping

gas is continuously monitored. the ending it soon switched jackson gas if we saw a gas emissions increasing, it would be assigned that there is activity underground, perhaps indicating a coming boat kind of corruption hospital in doors. today we know that the gas bubbles and mostly carbon dioxide, escaping from huge magnet chambers about 40 kilometers on the ground. but what does that tell us? does the gas come from the magma the russian brought forth 13000 years ago, which is still slowly cooling? is fresh magma foaming onto the lake? a new study involving researches from several gym and institutes raises these question. numerous weak trim is a great depth indicate that magma easy in motion,

but they're in those to the signal. so i thought that the volcano was preparing for another option. the so the west, the famous mugs are evidence of how volcanoes shaped the landscape of the deep fines of the eiffel divine failed mon you down is locally cold the month of the dead. because of the neighboring symmetry, the, with its closed crate to ring, the pull them out is the deepest at more than 70 meters. it seems both unless the the

sofa told her so cloudy, of the buggy, but the shelton mare and ma is the most beautiful. she is published a book of underwater photos from the crater lakes, which she worked on for years. the fact there under the trees there, always fish on one side. so i can to take there because i smoke perch always hide under the trees among the branches. that's nice to, i'm always happy to see the dawson the she comes here again and again, even when the temperature is dropping, the full. but it's the very special under water. well, the, the iphone mouse that fascinates the most of the

below the surface, the water of the mazda is still remarkably clear. no matter of the season. at this time of year, the water is only 10 degrees celsius. in winter, it goes down to 3 or 4 degrees the much what happens would assume that it's in a coffee. sometimes it feels like the caribbean because of the turquoise blue water . and there are so many fish of tina fisher. if you just float quietly available to them right by you, by

a common and when you died kind spot page by car and tension the hatch, there's really a lot to do as a smokeless, um refuge says in down here flora and phone a bound. although most of the most have no regular water in float. this fed solely by rain morsa, which 1st sleeps through volcanic rock, lay as before flowing into the ma. well filtered and clean, the lesson is done. yeah, that's on. so what fascinates me is the depth of some of them are supposed to be. the programmer is 17 meters deep and they're striking man and mark is 35 meters deep on monday you can get a feel for it. steps at the creature room when you see how the sharp drop continues under the, on the shore, doesn't look like one. was there something we need to be aware that it could go off

at any time? that's just the way it is on folks. so the last direction was 12 or 13000 years ago. scientists say one should occur roughly every 10000 years. so in fact, we're overdue. the mazda and volt tenant cones grace the landscape within magical chum, and to test to the fiery past of the volcanic awful. the volcanic activity use to every way, even if it's not always apparent. at 1st glance, the

interval penny going full region. the earth surface is rising by about one millimeter per year, even more in some places. these can only be measured from high in the air. what's causing this? is it the gas is rising from the magnet chambers, deep, underground pool, hot springs, the, when the food comes to the only full traces of possible kind of captivity can be found in the topography of the landscape. the bustled columns rise from summit. the numerous volcanic cones often hicks, i can know the figures which shaped thousands of years ago during a volcanic eruption when hot lava escaped and then slowly cooler. the

in the quarries of the volcanic eiffel lava best sold has been mined for centuries . as here near the village of strewn in the past, the hard stone was used for building houses and paving roads. even the banks of the rhine were fortified with 6 sided vessel, collins. today the stone is mostly crushed into gravel and grits bene down is the most. are strewn stone. he manages the b quarry and knows the long history of the place for you in the eyes are solid and beyond. there were 3 big of options here. 34000 years ago of this concept, and this whole valley filled up with lava follicles. the geologists are still looking for the old of back valley down here, and then also does of the others left off the, the lava flows solidified and phone the wide. so the major stick layer of basso,

here's the funds of the companies there. for example, you can tell the difference. and down below you can see the bus on flare and further up wordly where it gets more reddish. you can see that there are a lot of asking, and although you can really tell that there is a hard to just look back there, that's the bustle to there. you can see the love of the 1969, cory workers stumbled across a sensation. a blast released a huge rock formation from the corey will 15 meters up the head 1st. they weren't sure what they were looking at. a cool sample cleared it up. it was a gigantic lava boom that had been flung out of the volcanic crater. the strong love of them was discovered back there and just lay there for some time

. finally, they were just a policy of strong decided they wanted to them. the question was, how to get this thing over there. it weighs $120.00 tons to them. how do you move a stone, measuring almost 5 meters across over the fields from the quarry to the village? we don't watch the wind is blowing up on up to a lot of pieces in mid deadlines and obviously they waited until the ground had frozen over the winter with the eyes and stuff into the 5. then they welded big iron plates together and rolled the bomb onto them. when i thought did i, that should be, it took a large caterpillar and a bulldozer, crushing from behind to move the boulder across the field to where they wanted. it decided though i'm very familiar with the joint real come from the cool sample revealed that the lava bone consisted of many layers that had built up one after the other around a cool like an onion. a lot of them was probably flung upwards during the rupture,

and then repeatedly rolled back into the crater of the active volcano. in the process, it became sick and stick before it was finally encased in molten lava, where it remained until it was exposed in the quarry the today it's the main attraction of the smooth village of strewn. volcanic stone from the icy region was covered to building materials as early as the middle ages. the maria last abbey was built mainly as of dog. bustled and light tough. the at

austin cathedral tough is even found on the night sided central structure. the famous caroline, gee, an octagon, the v. tenix stone from the nearby only only field was also shipped along the rhine to help build cologne's cathedral and ice old tough was continually used for repair. with brave men from the mineral rich village of vi been helped the 19 o one a railroad line was built now popular with tourists. as the val khan express these through the stone, like tough thomas and bustled to the rhine at the winter hub or in bruise,

it was then load it onto the ships a lifeline. so the iso and a stroke of luck for the village of 5 in whitfield county, corruptions, 400000 years ago, deposited a massive layer of tough perfect building materials for churches, the tough he's light and easy to work with the same. if you look back from the 19th century onwards, at the construction of cathedrals and volt ribbing you realize this is ideal material lightweight and able to bet heavy load. just a nice po. why is the immense black ideal for the slender arches stretching toward the heavens? the worlds of ham, but also built with tough from vibe in the stone masons,

gave the stone and its characteristics, surface texture with him. is she those? and which is a f o r y o for the q and shit. the do for the corey was also the production site in the stone was still dumped when it was brought to the store house on lava and then cuts into rough sizes for the stone masonry, steinmetz swish extortion through stuff i over at the stats of the 20th century mold in 1200 stonemasons. what to you? tough from vi been growth are real, boomed to the small village to gush. each vice for shy and tough is a soft stone made up of solidified default kind of ash, depending on where they are found. and see the layers can be course, are quite fine, good guns, pine,

a dungeon debt to show how is that a hit does eat minus the number of houses here, where you can see that the master's and the cory owners had the money to have a leverage besides built on the apologize and the vibe in was able to afford its own water and sewer network earlier than on the villages and had electricity as early as 1915. but the demand for tough fell from the 19 sixty's on woods and the boom ended today. the many tough houses still bear. witness to the village is full of prosperity. the many volcanic cousins of the iphone,

windows only used as quarries. some of them still provide living spaces today of the, for the rulers of the middle ages. the top of such a volcano was a good place for a fortress. there were plenty of stones for building and was a panorama old brook console, for example, seats proudly a top of 460 meta high volcanic cone. the new a book stands even higher as an altitude of more than 670 meters. but he's best known for the famous race cools at the foot of the mountain. the renewable agreeing was originally built to provide the pool eiffel region with a new source of income. and under the ass votes on which famous racing drivers have done their laps, line message of love, of best salt,

from the quarries of the volcanic iso to state your abilities. even when burying a numerous loads made them the ideal foundation the today, it's almost forgotten that the ancient ruin of new book castle sits on an extinct volcano. but the volcanic origin of many places can be seen from above the room. a bed is a cone and solidified slag in front of it. is this true ma? it's almost completely sealed it up the sum of the extinct volcanoes provide the perfect conditions for recreational athletes. the may have failed. ma, for example,

is popular with powered light is the what sits the smaller apart from others is the form of its crate to rim. eats very steep and so exposed in some places that it makes, but just the right take off. slug. above the steep curved crater ring, you can fly perfect circles if the wind is rise and with the views like this, it's like a dream come true. the, the volcanic county police of world of water and not only because of its many months, there are plenty of places where water rises to the surface. as in the voltage shipped with its steep walls, the volcanic trends of the list

spectacular, but still valuable for the region is another phenomenon. there is springs everywhere in the eiffel. some hidden in the middle of the forest. andreas schuler from the volcanic eiffel, g. a puck knows where these trays come from. in the case of the guys in under now, it's carbon dioxide that drives the ground water up through the volcanic rock. the, that's what the zone. the special aspect of this area is the fact that the water contains not only minerals but also a significant amount of carbon dioxide which device month oh is the same and we know from chemical studies that this c o 2, like other gases, originates from the venting process of the magma deep in the cross list and the

opera mantles as well. so you could say that the iphones, mineral water is also contained, the brass of the volcanoes and height in the would raise these celtic for willing spring, the dust. this is here, this is the dash side to phase it's carbonated, it's fusing and also it has a very, very high i am content on top. in fact, it's the mineral water with the highest i am content in the volcanic iphone isn't got if you know we con josh, i darrow stein down. almost every community here has its own spring. the settlements grew up around them. these at least this odds and so mine and been of these waters contain minerals and the guns and a number may even have medicinal applications,

intuitive properties. so good looks to be. and so the idea arose to capitalize on these properties, to bring some cash into the regions a month, and also it looks good to me like your opinion. today, the bo county calling police known for its many varieties of curative mineral water . the ruined lake in the north west of the eiffel is also a drinking water reservoir. a massive dam holds back the ruler river at almost 80 meters in height. it protects the people down stream from a catastrophic flood. but what would happen if the dam was damaged, say, why a powerful this quake. this is why deep down in the dam daily inspections are performed to ensure everything is in order. this is the job of damn safety engineer band. how to hook in the

pendulum shows every little movement, minimal swings, and normal. they main madame is functioning properly. but what is the nearby volcanic eiffel stance to rumble? if the volcanoes reawaken the 1st quakes would be the 1st signs related to my inbox, when that's when we're talking about around 200000000 cubic meters of water. tom height of 77 meters. if something happened it would be huge. and so we just have to make sure that the safety is guaranteed around the clock is here in the fall south of the volcanic, only 2 lines, an important measuring station else console stands and assigned valley of the most a river. the doctor brigitte

took snuff by a intruding hits. besides my logical observatory at cologne university, she and her colleague klaus fleischer visit the 12th century console regularly. they have no interest in oreos or targets. they going underground the here in the deepest volt of the castle, directly on the rocky ground. the university has installed a highly sensitive science, mcgrath it registers every vibration, no matter how gentle the mitzy i'm the i for i'm this will here any i said we have on average about 50 to a 100 tremors a year. but most of them are so minor that they cannot be felt by humans since my

form mentioned bonnie baldwin. especially what's this distance remo? exactly. isn't that something let us give us just before 12 or 12. it will have to take a look later. it was relatively short quarters. oh, those were just so this waves from a bloss to thing and then from nice thing, one of the calls that could be this course to be most of the strongest quick we have reported with instruments was in 2007 near. besides, which had a magnitude of 3.9 and was felt over a great distance and the found on the bottom it was in 2015, but this one is my logical station recorded an unusual phenomenon that is occupied the scientific world ever since. first trim is from deep beneath the awful, the

doesn't alter, keeps me in the dark, based with the deepest quakes ever recorded in germany. and they had a special signature. the only thing that's what they look different from the quakes we usually see here is that this does not necessarily mean that maxima is rising, but there is definite movement and with the movement that could indicate that maxima is gathering again on the ground. the volcanoes becoming active, these raises questions, the emissions, even the summit in which areas should we actually expect this? mainly in the area of lake laugh or perhaps even further west, where volcanic centers were more recently active. the goal is to better understand what is down there and how dangerous it may be. a goal shed by seismic geologist, professor russia, to at the federal academy of civil protection. for his work,

the measurements are important to indicate is the, the people's insect line is 9, the shoot to go in. these earthquakes, very small trim is open ended the interesting point because such an accumulation may full cost of volt county corruption. hospital fine is that worked really well with a lot palm interruption to see if we had size mix signals that effectively full cost this maxima rise, the market pieces. the might be some lockman of duke and trinity, the diesel, loud enough time to prepare thousands of people for the massive erupt sion of cooper in the house and to bring them to safety from the ash and red hot lava knowledge, which is just as valuable for the ice will be here more in time. i think this is by

steve. this idea of what we're doing here at the moment is passive. we're just listening to the us and trying to interpret signals coming from different depths is, can you hear me now? let's see to the earthquakes at lake last, where the deepest earthquakes in all of gemini a record. they go down to about 40 kilometers, which means that we have to position additional devices and listen to different locations against window she the with us as to as possible. and that's what we're working on. and why the eiffel is a real laboratory for us. a moving research project and why it is actually a jeweler for research of volcanic activity in germany this weekend is moving towards the end of june, bonus, bio of fire still smoldering deep beneath the ice. so no one knows when the

volcanoes will awaken. but one thing is certain we will be ready for it. the the answer of the conflicts own with tim sebastian, i guess this week is electric considering co ukrainian. m. p. angelica for the parliamentary assembly council of yours for a year ago, gone to ranko, had post price because the landscape and reservations about him. because he still believe this presidents will be due crying to victory conflict. in 30 minutes on the w. refugees. welcome. one german vintage takes in 5 times as many people as the official quote to require.

how is that possible? many residents for the test refugees and funding language courses and jobs. we accompany one of these volunteers and is to help focus on 0. in 90 minutes on dw the, the top calls to everyone who wants to know more about the topic that concern us about this story is beyond the headline world in progress. the w talk costs the

this is the w news life from the military plane crash inside russia. public schools for an international investigation. brushing media report say those black foxes have been found at the crash sites, pasco, and key believing each other for the disaster. thousands and he cravy and soldiers for allegedly on board heading home in a christmas was also coming out from the program is road rules, a rev review permit staunchest ally, the us pop to an a tap on a you and shelter. and han eunice which kills 12 and pools.
