10:15 am
many called to the legal ization of same sex marriage and greater rights for sex workers. bank hawks, newly elected governor joined in on the festivities, where he announced that pride month will become a regular celebration in the capital. that's all for now, but stay with us for documentary, looking at germany's volcanic eiffel region. i'm michael of good, more news and 45 minutes. it is a secret war, the scene. endless one, absence of the conflict between iran on the one hand and israel in the united states on the other. for more than 40 years, the adversaries have been irreconcilable. the long war, israel, iran usa, starts june 15th on d. w. the
10:16 am
volcanic i full a landscape forged in fire, shaped by awesome elemental forces, deep under ground, huge glowing chunks of rock. ash that covered everything in minutes and formed a one of a kind landscape. the volcanoes fell silent some 10000 years ago, but they are only sleeping is something brewing deep below the surface of the eiffel. how great is the danger that the volcanoes will rule back to life?
10:17 am
in the east of the volcanic eiffel, near under knock, the forces looking beneath the earth showed themselves a cold water geyser, the highest in the world. every 2 hours, the water jet erupt, reaching up to 60 meters in the air. the guys are leaps, explains mineral adjust thorsten lambert's the facility soon is c, like as yours, wage guys are a russian is unique data just as each volcanic eruption is unique. latasha said, the rupture unleashes powerful volcanic forces deep beneath the eiffel. as carbon
10:18 am
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 water column is propelled upward. just look, man, just eat bugs in it, but ask on here you can really see and feel the whole volcanic process this, these, but helps you understand the pressure and power behind it. should another volcano arrived in the eiffel in bonds yet i didn't because present but when will that happen? the volcanoes of the eiffel were long thought extinct. now we know there only dormant deep under ground. the cauldron is still bubbling.
10:19 am
the traces of the last inferno, a still clearly visible to day at 1st glance, lake laugh 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. it's traces can be found on the near by vin gets big front. ne amended the geologist goes to hoffman. if bon university, the wool is a window into the distant past. the launcher for that's a 1000 johns are 13000 years ago. this landscape didn't look fundamentally different from to day, and then suddenly there was disclosure and at hurled ash and rocks some 40 to 50 kilometers into the atmosphere. feeling sure that
10:20 am
the massive eruption lasted several weeks as 1000 degrees celsius. magma met a groundwater reservoir. ah, the mountain top above was blown off by an explosion of steam, as a huge column of ash was catapulted kilometers up into the air. in one is steve, sir. at some point, this column collapsed and red hot ash rushed through the landscape lunch along the valleys and through the broad valley. for instance, when it reached the rhine river, which already existed back, then it cut the river off. ash and debris swept over everything and left behind a blanket, several meters deep and
10:21 am
scrub gun. oats. follow from these were colonels both arm to south stone, descried this volcanic eruption, damned the rhine and created a reservoir around. what is now if you today is the law to damage. at some point the dam broke and the hunters and others settled in the area experienced to catastrophes and one lifetime con oh sport. first option i volcanic eruption and then a gigantic water search that went to all the way down the rhine valley into today's netherlands. as div will can exclude zorn done as of this volcanic explosion of it was more an explosion than an eruption. this explosion, 13000 years ago, left us traces were, as you can see them on the wall here. does it for us. these are, this is like a history book. we can study it and essentially read had this volcanic explosion
10:22 am
happened, kill off each singularity as like a high resolution snapshot of an individual face of the russian hill torn. ah hoffman regularly leads groups of scientists through here. the layers of the wall reveal the stages of the volcanic eruption he does. it doesn't say english does the anomaly riser in. so i was crazy, is that such a layer usually shows several tens of thousands of years, a few rungs and here. and here we have a 30 meter cross section that represents a few weeks at most. this is just a few minutes. this single layer is a collapsing cloud of embers. one, ready here. there's no holes in him. and if i pull the stone out, this is maintenance at night and on the 3rd ring we an a we night with a rare blue mineral expelled from the magma. the
10:23 am
eiffel is one of the most important sites for it in the world. the north american bank, if you look at that under a magnifying glass, it's really beautiful. the vin gets bagged vantage. part of the unesco volcanic eiffel geo park hoffman and his team developing an app to allow virtual travel through the volcanic landscape. everything is precisely scanned and measured. ah, you have to give parking, come i, she using the volcanic eiffel geo park as a reference model, as it's the very 1st gio park in germany that offers the completely digital turning package. all points of interest in this park can be viewed and the sapir guitar up with the app works with super precise satellite data, much more exact than basic navigation or hiking apps.
10:24 am
for when hike yona deserve vanity money and we want to not the while back there and 3 d doff up to do this, you need a lot of photos and the right image processing software to see if the john can get close enough. you can get a good 3 d image, convert the dental one on the drone can also reach sections of the wool that are otherwise difficult to access. the camera scans at high resolution, so the computer can later generate a detailed image. the various lay is in the wall or especially interest. they consist mainly of
10:25 am
pumice and tough interspersed with rock fragments dragged up by the volcanic eruption. ah, the sea and having aspect munson fuzzy. the thing that's back van shows all the sediments this volcanic eruption unearthed, and it's been geologically proven that there were different eruption phases. you have to imagine, it's not like an exploding powder keg by like several atomic bombs on it. and that's how powerful over at home bomb. so ganesh madison, with bacon. i knew i was forced, his laugh aziz, or under a 100 we can't rule out a fresh eruption. unlike life or other volcanic structures. here in the eiffel said, we can only hope that would be enough. warnings was, for example, in the form of earthquake swarms on that. we don't want to paint a horror scenario. but if what happened 13000 years ago happened again to day in a densely populated region like the rhineland, that it would be catastrophic island to miss kettle fall large
10:26 am
cities like bon industrial plants and refineries. the rhineland chemical belt cologne, with more than a 1000000 people. how can the regent possibly protect itself from such a natural disaster? the federal academy, the civil protection and disaster assistance. b, a b k in the our valley generate scenarios for such disasters. professor klaus writer is researching possible consequences of a fresh eruption of the lake. lock volcano. to look, nibbled. soon. soil gave him disable. there would be a very high eruption. column design of the echoes would be closed off immediately. music landing simply were be possible,
10:27 am
then you'd have to see how far and how quickly the rushing cloud spreads, depending on the wind direction would have increased or not too much does uber legal, stossel, fulton, we'd have to consider whether roads were still usable to whether critical infrastructure like trains and the power grid still worked. current to certain vehicles may be able to drive on the free ways to evacuate people's ebook, but then things would get difficult. there are no other escape routes as you can extend. the problem is that in strongly con to landscapes like the r valley or he and the eiffel people have settled in the valleys. so there are only 2 ways out and forwards and backwards. there is no other option. so i b host to comb poon to luke on proof that ah is good enough. the move isn't of a shy oh, funky, depending on where we are,
10:28 am
they will probably be casualties as well for that. so and d to hospitals must be prepared for the specific types of injuries that volcanic eruptions can cause cotton, especially burns restart. so they have to have dedicated burn unit. so, but they also need specialized units for se amputations and emergency surgical procedures. if that would be necessary after an earthquake by beam, does this less unless we just know modern? ah, that is it even possible to prepare for such a disaster? if a coolant spleen, the odor 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 to light and that may be a mistake, but i don't think it's absolutely necessary. unlike with flooding of volcanic eruption allows response time because of this. it trust me at site ah.
10:29 am
volcanic eruptions come with ample warning in the form of tremors and gas emissions . at lake law, it's easy to forget that the ground below has still not settled. the old volcanic crater is a unique natural paradise. but at the lake's eastern shore, there are still signs of volcanic activity. mo fits carbon dioxide, bubbling up through the water. ah, near by the jesuits bill to study and recreation home for young monks in 1970. when 8 of them died, inexplicably gas emissions from the lake shore were blamed. the
10:30 am
young men were buried on the grounds of today's maria law abbey, in the crit, under one of the smaller chapels, whether the monks really asphyxiated has never been confirmed. mm hm. but professor hoffman and his team of geologists, the lake is of great interest the mo fits are important to better understand volcanic activity in the eiffel and to observe any changes with you and give isn't shoplifters. and speaking to a junior scientist is the more feathers show that there is still volcanic activity
10:31 am
here is to say it's not only ever molten rock that comes out of the ground in gordon. it's mostly gas gas. and this is why the amount of escaping gas is continuously monitored. and we have seen for stack and gas if we saw gas emissions increasing. so it would be a sign that there is activity under ground, perhaps indicating a coming volcanic eruption host or invoice. today we know that the gas bubbles are mostly carbon dioxide escaping from huge magma, chambers about 40 kilometers under ground. but what does that tell us? does the gas come from the mag mother eruption brought forth 13000 years ago, which is still slowly cooling? or is fresh magma forming under the lake? a new study involving research has from several german institutes,
10:32 am
raises this question. numerous weak trem as at great depths indicate that magma is in motion. but there are no further signals so far that the volcano is preparing for another eruption. further west, the famous mars are evidence of how volcanoes shaped the landscape here. the deep eyes of the eiffel, the vine feldman near down is locally called the mom of the dead because of the neighbouring cemetery. with its closed crater ring, the pu vermont is the deepest at more than 70 meters. it seems bottomless. ah.
10:33 am
fo photography cloudy a v by gibbet, the shell can marin, mom is the most beautiful. she has published a book of underwater photos from the crater lakes which she worked on for years back there under the tree. there are always fish among i. once i gigantic hike, bear declined the smell patch always hide under the tree among the branches. that's nice too. i'm always happy to see that dawson she comes here again and again, even when the temperatures drop in the full. but it's the very special underwater world of the eiffel mass that fascinates her the most
10:34 am
ah, below the surface, the water of the mars, he still remarkably clear no matter the season. so at this time of year, the water is only 10 degrees celsius in winter, it goes down to 3 or 4 degrees. oh ah, my husband's a discussion that it's in a coffee. sometimes it feels like the caribbean because of the turquoise blue water
10:35 am
. and there are so many fish f tina fisher, if you just love quietly, right by you, by common. and when you died by heart and tension the hash, there's really a lot of does this look ish, su to 0 me down here, flora and fauna a bound. although most of them have no regular water inflow. they're fed solely by rain water, which 1st seeps through volcanic rock, lay as before flowing into the mar, well filtered and clean the rust mish done. yeah. that's what fascinated me as the depth of the mars, which the pulver mars 70 meters deep. and i can man and mar is $35.00 major seat one month. you can get a feel for that that the room when you see how the sharp dropped continue under the
10:36 am
short one was that we need to be aware that it could go off at any time. that's just the way it is and fossil so let's all the laughter option was 12 or 13000 years ago. scientists say one should occur roughly every 10000 years. so in fact, we're overdue. me . mars and volcanic cones grace the landscape with their magical charm. and attest to the fiery past of the volcanic eiffel. mm. ah volk, any captivity is still everywhere,
10:37 am
even if it's not always apparent at 1st glance. ah, in the volcanic eiffel region, the earth's surface is rising by about one millimeter per year. even more in some places, this can only be measured from high in the air. what's causing this? is it the gases rising from the magma chambers deep under ground, or hot springs? when the full comes to the eiffel traces of past volcanic activity can be found in the topography of the landscape. bustled columns, rise from some of the numerous volcanic cones often hexagonal. the figures were shaped thousands of years ago during a volcanic eruption when hot lava escaped and then slowly cooled.
10:38 am
in the quarries of the volcanic eiffel, lava, basalt 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 battled columns. today the stone is mostly crushed into gravel and grit. bene dow is the master of sharon stone. he manages the big quarry and knows the long history of the place or a few and either on the, on the were 3 big eruptions here, 34000 years ago. have these has gone to this whole valley filled up with lava follicles. the geologists are still looking for the old off back valley, down here. they're not. thus, i'll fucked up the
10:39 am
lava flow solidified, and formed a wide 30 meter thick layer of basalt. now here's the phone to my grandmas. you look over there, for example, you can tell the difference. down below you can see the basalt lair and further up bridge road where it gets more reddish. you can see the lyric lava, you know, that he can really tell the layers apart. so just like back there, that's the basalt layer. and you can see the lava poverty. in 1969 quarry work has stumbled across a sensation. a blast released a huge rock formation from the quarry wall, 15 meters up. at 1st, they weren't sure what they were looking at. a cor sample cleared it up. it was a gigantic lava bomb that had been flung out of the volcanic crater.
10:40 am
regarding what album of the strong lava bomb was discovered back there and just lay there for some time. and finally, the municipality of strawn decided they wanted it sooner than the question was, how to get the thing over there. oh, it weighs $120.00 tons on. how do you move a stone, measuring almost 5 meters across, over the fields from the quarry to the village with odds, the winders or not been up golardo visited with them? i and the other is they waited until the ground had frozen over the winter islands references. i'm good flies and they welded big iron plates together and rolled the bomb onto them or not. on mid i'd ashby, i took a large caterpillar and a bulldozer cushing from behind to move the boulder across the field to where they wanted. it fell beside other online retrieval rockefeller. oh, but where did the giant rock come from?
10:41 am
the cool sample revealed that the lava bomb consisted of many layers that had built up one after the other around a cor, like an onion. the lava bomb was probably flung upwards during the eruption, and then repeatedly rolled back into the crater of the active volcano. in the process, it became thicker and thicker before it was finally encased in molten lava, where it remained until it was exposed in the quarry. today it's the main attraction of the small village of strewn. volcanic stone from the eiffel region was coveted building material. as early as the middle ages, the maria la abbey, was built mainly out of dark basalt and light tough.
10:42 am
ah, that often cathedral tough is even found on the 8 sided central structure. the famous carolyn gee, an octagon volcanic stone from the nearby eiffel was also shipped along the rhine to help build cologne's cathedral. and i full tough was continually used for repair work, brave men from the mineral rich village, a vibe, and helped in 19 o one a railroad line was built now popular with tourists as the vulcan express. this
10:43 am
brought the stone, like tough pumice and basalt, to the rhine. at the winter harbor in bro all. it was then loaded on to ships, a lifeline for the eiffel. and a stroke of luck for the village of vibert where volcanic eruptions 400000 years ago, deposited a massive layer of tough perfect building material for churches. ah tough is light and easy to work with flu. then if you look back from the 19th century onwards, at the construction of cathedrals and vault ribbing you realize this is ideal material lightweight and able to bear heavy loads. if thus i nice. oh i the immense length ideal for the slender arches stretching toward the heavens.
10:44 am
the wolves of hamburg were also built with tough from viber. the stone masons gave the stone its characteristic surface texture, with hammers, chisels and wedges. oh, wow. oh, look, you'll see it that day. i quarry was also the production site ish in the stone was still damp when it was brought to the store house on lava and then cut into rough sizes for the stone mason research, i imagine, swish discourse through stuff. i hope so at the start of the 20th century. more than 1200 stonemasons worked here. tough from vibe and brought a real boon to the small village tooth brush. each vice shine tough is a soft stone made up of solidified to fall contact ash. logwood,
10:45 am
depending on where they are found, the layers can be course, are quite fine with guns, pine dungeon at the shower. so here, the jeep man, that there are a number of houses here, where you can see that the masters on the cory owners had the money to have elaborate facades. built on da avenue for john jewish vidal was able to afford its own water and sewer network earlier than other 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 to day. the many tough houses still bear witness to the villages, former prosperity
10:46 am
the many volcanic cones of the eiffel, when not only used as quarries, some of them still provide living spaces today. for the rule is 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 what a panorama old brook cancel, for example, sits proudly a top of 460 meter high volcanic cone. the new a book stands even higher at an altitude of more than 670 meters. but he's better known for the famous race course at the foot of the mountain. ah, the newer bo agreeing was originally built to provide the poor eiffel region with
10:47 am
a new source of income. and under the asphalt, on which famous racing drivers have done their laps, lie masses of lava basalt, from the quarries of the volcanic eiffel. did your ability even when burying enormous loads, made them the ideal foundation? ah, to day it's almost forgotten that the ancient ruin of new above castle sits on an extinct volcano. but the volcanic origin of many places can be seen from above the room. a bag is a cone of solidified slag in front of it is the strewn mar. it's almost completely stilted up. sh. some of the extinct volcano is provide the
10:48 am
perfect conditions for recreational athletes. the mer failed mar, for example, is popular with paraglider is what sets this mar apart from. others is the form of its crater rim. it's very steep and so exposed in some places that it makes for just the right take off slope. above the steep curved crater rim, you can fly perfect circles if the wind is right. and with a view like this, it's like a dream come true. the volcanic high full is a world of water and not only because of its many mars, there are plenty of places where water rises to the surface. as in the vault,
10:49 am
she looked with its steep walls of volcanic tress, less spectacular, but still valuable for the region is another phenomenon. there are springs everywhere in the eye full, some hidden in the middle of the forest. andreas schuler from the volcanic i full geo park, knows where these drains come from. in the case of the guys are in under now. it's carbon dioxide that drives the ground water up through the volcanic rock. that's the position the lithia, the special aspect of this area is the fact that the water contains not only minerals but also a significant amount of carbon dioxide. dove iceman oshima. and we know from chemical studies that this c o 2 got like other gases
10:50 am
originates from the venting process of the magma deep in the earth's crust and the upper mantle. so you could say that the eiffel is mineral waters also contain the breadth of the volcanoes and heighten the word drain is celtic for welling spring dust. this is here, this is the dash i to raise it's carbonated, it's fizzy and also has a very, very high iron content on top. in fact, it's the mineral water with the highest iron content in the volcanic i forced my eyes and guardian of economy ah, dash, hide garage, dine down. almost every community here has its own spring. the settlements grew up
10:51 am
around them. at least they saw in some island, men of these waters contain minerals and guns, and an may even have medicinal applications, intuitive properties like a lost via and so the idea arose to capitalize on these properties to bring some cash into the region. so ma hm. oh, it was getting the lagoon supreme. today, the volcanic eiffel is known for its many varieties of curative mineral water. the rural lake in the north west of the eiffel is also a drinking water reservoir. a massive damn holds back the roof, a 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 by a powerful earthquake? this is why deep down in the dam daily inspections are performed to ensure
10:52 am
everything is in order. this is the job of dam safety engineer, band heart hookin. a pendulum shows every little movement. minimal swings are normal. they mean the dam is functioning properly. but what if the near by volcanic eiffel starts to rumble? if the volcanoes reawaken earthquakes would be the 1st signs we are even to my end, what's one that's why we're talking about around $200000000.00 cubic meters of water at a dom height of 77 meters. if something happened it would be huge. and so we just have to make sure that safety is guaranteed around the clock as it is here in the far south of the volcanic eiffel lies an important measuring station
10:53 am
else council stands in a side valley of the mosul river. doctor brigitte took snuff maya in truen heads the signs my logical observer treat at cologne university. she and her colleague klaus felicia, visit the 12th century castle regularly. they have no interest in orals or targets . they're going underground. ah, here in the deepest vault of the castle, directly on the rocky ground, the university has installed a highly sensitive size, mcgrath. it registers every vibration, no matter how gentle it's your life. and this will here any ica we have on average about 50 to a 100 tremors
10:54 am
a year. but most of them are so minor that they cannot be felt by humans before mentioned bonnie rosen. ah asked us no, let's this distant tremor captain. exactly. isn't that something honest? if i was just before 12 we'll have to take a look later on. uh huh. it was relatively short quarter of all of those were just surface waves from a blast offering van from a spring or a lot of house that could be as close to be him as their strongest quake we had for a quarter with instruments was in 2007 near plight which had a magnitude of 3.9 and was felt over a great distance and found on babylon. it was in 2013 that the size my logical station recorded an unusual phenomenon that has occupied the scientific world ever since. birth tremors from deep beneath the eiffel
10:55 am
ah has not, it gives me the advice lease where the deepest quakes ever recorded in germany. and they had a special signature having not what they look different from the quakes. we usually see here that this does not necessarily mean that magma is rising, but there is definite movement and with eagles toughened movement that could indicate that magma is gathering again on the ground. are the volcanoes becoming active? this raises questions. making a mismanagement in which areas should we actually expect this off site on mainly in the area of lake law 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. i don't, does that out of seem a goes shared by seismic
10:56 am
geologist, professor russia at the federal academy of civil protection for his work. the measurements are important indicators, dizzy themes intake line to supply the issue to ruin these earthquakes are very small tremors often and the interesting oh because such an accumulation may forecast a volcanic eruption host behind is that worked really well with the law palmer eruption this year. i am a, we had seismic signals that effectively forecast this magma rise. de markesha. he says, there might be some lockman, austic, an uncritical this allowed enough time to prepare thousands of people for the massive eruption of cambridge. yes. and to bring them to safety from the ash and red hot lava
10:57 am
knowledge, which is just as valuable for the eiffel bus via marrington montes is perceived as i see. what we're doing here at the moment is passive. we're just listening to the earth and trying to interpret signals coming from different depths. this could him now see to the earthquakes at lake lock, where the deepest earthquakes in all of germany, a record, if they go down to about 40 kilometers it, which means that we have to position additional devices and listen to different locations and guns window. she to him pulled ah, with us is disposable, and that's what we're working on. and why the eiffel is a real laboratory for us. i'm a moving research project. and why it is actually a jewel of research of volcanic activity in germany this weekend. this was in deutschland, a jew born of fire,
10:58 am
a fire still smouldering deep beneath the eiffel. no one knows when the volcanoes will awaken. but one thing is certain, we will be ready for it. ah, a mandy lou. in good shape. speak as a pineapple, heavy as a toasting human brain. here you can learn how it works, what it means, how it can be trained. and we answer one of human kinds. biggest questions to male and female brains work differently in good shape. in 30 minutes on d, w with
