11:30 am
i don't see a, this is a mass on this, not c, so known to go out of battery or something then that's okay. that's the nanda foundation. one box to the next. find out about robina story in some migraines. reliable news for migraines. wherever they may be, november 2023, off the coast of u o g. but japan under see volcano erupted giving birth to a tiny new island. researchers are studying interruptions like this and the laboratory, hoping to find out more about what power is volcano volcanoes in their mystery. how close and personal on this edition of dw science show. welcome to tomorrow. today. this is what
11:31 am
happens when hot lava meets will test. like during the volcanic eruption in hawaii at 1st, the law that doesn't cool down at all. then it starts flowing more like ribbons of honey dripping from a spoon before turning into chunks of stone and glass. at the same time, you see that the, from this pile open now crude sample, there is bubbles for me. let flip this image around. and these steam problems arising. but then they feel that there's cold or water around. so they instantly implodes and the bubbles never make it up to the surface of off my what the container knowledge is. anthony le more an overs cooper's a melting ground. volcanic rock. in this oven, heated to 1100 degrees celsius. sarah, only
11:32 am
a handful of lamps like this one here at unix ne maximillian university. they use for experimental canada g by researches us studying what happens inside a volcano. deep inside the dots where the maxima is before it tends to lava. when the volcano erupt. how does mack my phones deep in the are in demand to allow? does it make its way to the cross out as it involves stall in different places and magnum chamber, and then move up, install again, and then move up. and it's priming itself on the way to the surface. only about 5 or 10 percent of meg will make it to the surface. most of it gets stuck into across . so it across is a filter. and we need to understand that. so we need to actually start modeling the system as a whole, where nearly to there's a lot to learn. how does the mcmurry expand? how does it fracture? how does it seem to define young love at lee and his team built these ovens so that
11:33 am
they can follow the process step by step to see exactly how solid rock notes on the ground. not looking at any form in the top 200 kilometers. if the this month will, where the temperature and pressure conditions are right. even the, the document isn't everywhere. mama only melts in places where tectonic plates are drifting apart. and the pressure decreases, allowing the maxima to rise like an iceland, for example. cold places where one plates trace on top of another, on the presence of water allows the rock to mount despite the high pressure. that's how the volcanoes in central and south america were formed. the 1st place when locked in the notes is that what a cold hotspots places where the temperature is unusually high. hawaii volcanoes, for example, powered by hot spots. every volcano is different uninterrupted, in a different way. so that's why the team often head south field research,
11:34 am
like here to the long valley caldera in the united states. they gather volcanic rocks, and bring it back to the board train. for a long time, the process by which friction makes the volcanic rock the top as he rises up, the volcanic vent wasn't fully understood. that's why jackie kendrick studied help or conic rock. so rather against each other until they melt. this is something that happens when you rub your hands together on a cold day and you see this is also true of trucks. this happens in tectonic prices, and it also happens that volcanoes. and so here when we move on to samples task, one of the rich, the simulating one of these frictional context. so we want to understand what kind of emotions create what levels of heat inside of the results was captured
11:35 am
on video. it takes just a 2nd for the rock to mount. so at the beginning, when we have flip, we're going to see this kind of aspects created from the folks at the same. and you can see that from the house from the surface. and then very quickly, we're reaching a couple of 100 degrees and then already a 1000 degrees where we start melting. it can reach up to 1400 degrees to be friction alone as this thermal image shows. that this is quite remarkable. and this is not something that we were actually expecting when we pick out what maybe the most risky is not going straight into touch it afterwards because they really quite exciting samples. and the idea that you want to go and grab that, didn't get that in your hands right away is a, is very tempting, but it actually takes about 30 minutes to cool down to ring temperature. so we have to be careful not to jackie kendrick and her team discovered that the friction and doesn't just generate more heat. it also
11:36 am
helps folk interruption the, as the molten maxima rises, the pressure goes down. that allows the gases in the maxima to expand, the gas is phone bubbles, and that increases the volume of the maxima. well, decreasing it's density. that gives the maximum momentum until it finally reaches the surface where it's cold lava. is the same as a bottle of champagne and if you open open it too quickly, it splashes everywhere. and every time we open a bottle of champagne, oh but it was coca cola. we tried to regulate that with our hands. we do this systematically. all of us every day. so could we do the same with the magma? could we drill in a way, way we could control the gas coming out. so we prevent even to prevent disruption from happening. young. i'm on a and his team one to put those questions to the test at the crossland block,
11:37 am
my testbed in iceland the planning to drill a to kilometer long knocked my chamber to upset the maxima where it's normally hidden from view. and that hoping to figure out how to tap into that super heated liquid rock as a new source of energy. huge amount of energy and maxima. if you take one liter of magma at a 1000 degrees and you cool it slowly to room temperature, you obtain one megawatt. we have full kind of corruptions and mystery and artistry that they've reached for 5000 cubic kilometers. there's a lot of energy sitting there that the power entire country, the noise is energy, but it's also the source of all of these, the minerals that phone's are deposit, rare of gold compa all comes from them from the magna. so there's
11:38 am
a lot of benefits from them. similarly, the fluids are utilized for, for into a time on energy, but we also have lithium coming out of, of these fluids. so there's a lot of goods to magwell. volcanoes are a force of nature. the fascinating and frightening and there's still a lot less volcanoes can be deadly. as a visit to this archaeological site makes clear, the ancient roman city of pompei was wiped off the map when mountain to sue v as a ruptured almost 2000 years ago. what's it like for people who live here today? and i'm always a little afraid. you know, i live through 527 quakes with 2 small children. and i still didn't move away and
11:39 am
many people less but not me. and i'm wondering it as close as he, when there's a quake, we just wait outside. it's scary at night, but you learn to live with it and it will be thing. so the concern is understandable because there's another volcano here, along side mount vesuvius. disagree in fields. so let's take a closer look at the region. the place that at 1st glance is practically picture perfect. this is a famous volcano in southern italy. and so is this one rises towards the sky at the edge of a city. the other is basically invisible. the company for the great west of naples, isn't a mountain. it's a caldera, a cauldron like color that spends more than a 150 square kilometers. it may look innocuous, but underground, it's burbling in simmering. and everyone's wondering whether they're wrapped,
11:40 am
if you start challenging question how you will not see an interruption during my live here, come people agree because they're more than 80 percent of the city of what's on the lives on top of the company. so i think the called in for him to find the reps in almost 4000 years ago, steam and hot gases rise from the funerals pushing the floor the caldera upward, the that causes earthquakes, and is made the ground rise by almost 4 meters here over the last 70 years. so what's happening inside the volcano? scientists regularly analyzed the gases that escape here, and the gas is trapped in the mac that chambers several kilometers underground. some gosh, this are mostly because of the of the commodity process is mostly because of montgomery for example c o 2, but also some other, i know it's got this like you, nitrogen and so on. he said other uh gosh, just like me taught me,
11:41 am
things are mostly because of what is happening in the i deterred most east. and so in the shallower part of the system, the geo chemical data confirm that the long dormant volcano destroying the earth, the crust above it, is stretching and weakening. during the last thunderous face stopped and ongoing guys, a space started in 2005. it was reduced through on increasing the flux of seo, to which reaches value of about $45000.00 tons per day. this value rings becomes leg rate. one of the a to a mean it meters of both conic q 2 on this is the reason for which the most scientists are talking about the diesel. ok. no indices of angels will cannot disclose. it is a large and for fraser. so the credit is
11:42 am
a very high in 2012 the alert level and the region was set to yellow is the alert, went to orange and red. nearly half a 1000000 people would need to be evacuated within 72 hours. the volcano last directed in 1538, which is also the only historically documented direction about 40000 years ago. this area was shaken by a super option. a term that gave rise to the word super volcano. remnants of volcanic ash can still be found in eastern europe. elizabeth regional v. these great tactical, whether they're not ill, 7000 years fuck, you know, because so far i think i own the company and i guess was destroyed but these by just that option. so it was a very impressed to hit option in the label for for more and more
11:43 am
videos of burbling slides are going online. people are getting worried. is that worried justified? sandra ross tod, distressing to each. so just a day to the main, not me to come disagree our mainly drive inviting section of my commodity fluids inside the shuttle where i'd return most east. obviously at the moment is not possible to completely screwed up. so the involvement of shuttle of and smooth in my commodity intrusion, which obviously each a do the right stuff to prove, but bbc of under option in the future. but the magnet and these companies that guy has been burbling and flowing for centuries. the underground magnet chambers fill up an empty regularly, which explains the brady science and here the slow lifting and thinking of the earth's surface. it's evident on the collins and these ancient ruins. the residues shows that they were under water at some point. and then we surfaced next door in
11:44 am
the old harbor. there's more evidence of this up and down movement. many boats live beached on the sand here, understanding the brady science and then the region can help decode what's happening deep under the account era. but even with all of the monitoring, scientists still can't predict exactly if and when the super bowl aquino might erupt the sicily and the sounds of it is home to another big volcano, mount as it began belching lava and clouds of gas again in early december, 2023. can of russians like this be predicted? no 2 volcanoes are alike. some erupt by spewing lava, a gas and rocks into the air. others are relatively gentle. we can look inside
11:45 am
a volcano of course, but in the lab, we can show how magma explodes. maxima has very different properties, it's, it can be more like a, like a tar, you make the streets. this is to very slowly deform it, it can flow, but if you fast the deform it, it accommodates stress and it breaks. that's exactly what's happened. an explosive organisms. this cylinder was carved out of a large chunk of volcanic rock. to simulate a volcanic explosion between a show, a place is a cylinder inside a model. volcanic event, the gas has been sped into it, raising the pressure inside until it splits into fragments of all cannick material like sender ash and broken rock called pyro class and explodes. the experiment shows what happens in the conduit when the volcanic matter is objected upward at an ever increasing velocity. and how
11:46 am
a cloud form. so above a volcano, the, this gets the possibility to observe it with a high speed camera and really see what tract way and frank just how holes all the grades for large of a. how are they evolving and how is the direction of that then creating the flu and creating the ballistics being injected from the vocational which posts that has on the research team could even observe the lightning forming in the cloud when particles of false haneke, ash, fragments, and collide, they found that the smaller the particles, the more lightning there is in the plume. in 2022, the volcanic eruption in the south pacific country of tongue sparked the most intense lightning storm ever observed. each volcano is this next person that it is this different personality. so you have to study for each were panel how they behave. and with this, the 10 impulse, the forecast, what the con to
11:47 am
a focus on that. the volcanic rock here and the munich laboratory comes from around the world. because every volcano is different in their shape, vince porosity, magnet composition, and more. every volcano has its own personality. and every a russian does to the in december 2023, mount milwaukee on sumatra. erupted with little warning, just one of the counselors that russians, indonesia has experienced over the years. wonder option about 200 years ago was so powerful, didn't lead to the year without summer in europe. this devastating 10 for a rupture and went down in history. the
11:48 am
the rupture of 1815 deposited millions of cubic meters. volcanic material on some of our island come by law. i'm going with it. i believe 92000 people died and all 40000 straight away by the time that i didn't miss it the day we have these beautiful scenery with the money and we can see what happened in a 1015 here upon nothing of the so then for the 1815 was when the tamora volcano erupted the most powerful in recorded history. what happened on the island of symbolic was felt around the world. climate data confirmed that the russian costs global temperatures to cool with a devastating impact on agriculture around the world.
11:49 am
the in parts of asia, the monsoon rains, were disrupted, leading to drought in europe. so the cold and rain led to crowds failures and widespread famine, disease, and economic turmoil. the crisis also made waves in the world of art and literature . hers are sent to have inspired novels like mary shelley's frankenstein, and the use of light and color and cost barnaby. friedrich paintings captured this striking sconce in the darkness. the trout of the earth, catastrophe and creativity went hand in hand. it's even been plans at the interruption spark the invention of the bicycle or a series that's on present. but we do know why be a russian brought cooler temperatures. so if i got a low the level suddenly i'm going to be when a volcanic eruption injects action,
11:50 am
must be a tacit, and gas is into the atmosphere. i've gotten into the stratosphere. so by that all you have in for the, for a sulfate aerosols, or which the earth's rotation helps spread around the globe will be by walking editing. and those aerosols have a cooling effect on the earth. done by now, crops fail, thing going to be not that many animals can't find enough food. and so what are we going to say uh, but just to be back, indonesia is situated on the pacific ring of fire mountain bore on some bond is just one of more than a 100 active volcanoes. there. this called era is also a legacy of the russian of 1815. today, the area around mount tamora is a national park. it takes 2 days to reach the edge of the crater. for many people in indonesia, volcanoes have spiritual significance. with boston is highly controlling the witness that 1st hand. in 1847,
11:51 am
he climbed 10 boar and penned the depictions of eruption of the year 1815. in his pamphlet, he described how local people warrenton against climbing the volcano, wherever you set foot and fire are reps from the ground. people spirits inhabit the mountains, and those who want only to ascend in that region of kelly spear it's are faded to separate storms, tempest and certain perdition. before the disaster, people didn't realize that tumble ro might corrupt. nobody knew that mountain burrow was a volcano asper time in memorial. it had adjusted neither ash, nor lava, nor had rumblings revealed that it held chambers of underground fire. the admin, yeah. the one tamora comes from the word and bora. bora means to disappear in indonesian who lives with a town in front of it. as in tom bora, it means inviting me to disappear to him. i think i'm on that. let's disappear,
11:52 am
met him on the line, and it's a place that's never lost. it's mystery. i do not deny that i too felt a thrill of exhilaration as i became the 1st person since the terrible interruption to set foot on the crest of this mountain, which had a cheap such sorrowful fame and history. scientist today are still studying the or option of mount temp or geologist, climate scientists, and social scientists are all interested in the global impact of a natural disaster that took place more than a century ago. a disaster that in essence comfortable, aquino, and half the battery. but not, but at the number of elk and ologist believe or subscribe to the theory that the summit of mountain bore. i'm authorized, 4000 meters above sea level. 1 may not be able to move out loud. and because of the
11:53 am
$1015.00 a rupture, and it was essentially cut and a half ago, and what remains is only 2800 meters above the sea level. what about this? so again, my thought on that one more time loud and it was a disaster for local people. the flank of those people was a terrible thing to behold. strewn along the road where human remains surrounding places where others had been buried under lava and ash. villages were devastated houses had collapsed and lay half buried beneath the ash effect the following up on the, on the beach. in 15 a russian retreat kingdoms in the region of mountain bora, under lava and all that are buried them without a trace. someone in the past has got on and during the excavations along the co window track, the archaeologists have under the traces of community life fair, the year 1815. following up on that one of the including rice fields and the
11:54 am
housing complex as and human scale. it is a complex little man. then come on, come on. we see. the night sky on our ascent was peaceful. nothing like the evening of april 5th, 1815 when the 1st pillar of fire illuminated the night. the infernal left its 7 days before it subsided. mountain bora is what is called a strato volcano. it was formed by many geological layers. it has a steep, narrow cone. so is it possible it might have romped again one day. over the past 20 years, the region has seen many periods of increase seismic activity. small tremors in the ground and the vince and the ground called few more roles are emitting more volcanic gases and vapors. again. mountain bar is under observation. like many other volcanoes in indonesia, city. these are moving out of 127 active volk,
11:55 am
and i was in indonesia, almost 80 percent of them between 70 and 80 percent of them have an observatory station i kind of just have to we don't, we even have one volcano monitored by 3 observatory stations i'm up, each station has a size mcgrath up since they have the size of the graphs and binoculars that are they measure the wind direction and the temperature in simple that they have their him a couple of sensors to measure the temperature of humor rolls and sold the target was and so forth. we might also, but i thought is my goodness, our journey has come to an end. in 1847 when highly toner and arrived back safely from his ascent. his return was seen as a good omen. it was thought the curse had been lifted and the evil spirits banished the hope was that the disaster of 1815 would never come again. the celebratory gunfire, expectations, and singing, went on until dawn. that's all for this edition about volcanoes and there are many mysteries. thanks for
11:56 am
joining us. we'll be back next week with another edition of tomorrow. today. the science show on dw, see you that the, [000:00:00;00]
11:57 am
the, [000:00:00;00] the, a pulse, the beginning of a story that takes us along for the ride. it's about the perspectives culture.

saying it aloud. you guys would have being nosy, de la, good, everyone to king, to check out the award winning called called know how bad they cases an applicant. do they have good was i, when i told me that they don't have violence do this, and we go say tulsa tissue today, because then they go to that who set up. he has not been, you know, medical records on that otherwise. so not because
12:00 pm
the the, this is the w use like from the challenges of counting the dead in guns. that as the us again, was israel to be more precise and it's military operations. we look at how causes, how much fun, helpful, or hate documents, how many lines of being docked. so as military campaign sparks attacks on one of the world's most vital shipping routes. we look at the impact on trade and the new
