We are here at Fagradalsfjall   volcano. It's the 6th of July, 2023. And the reason why we're here is because  there has been a lot of shaking going on. Earthquakes, seismic activity and now scientists  are wondering if it's going to erupt again. I'm Ragga and I'm the co-founder of Lava Show and a lava ambassador, I like to call myself. And I have always been extremely fascinated  with volcanoes, geology and lava. And basically what we are now  looking at is that there may be yet another eruption on the horizon. And what's interesting about that  is that Iceland is one of the most volcanically active places on Earth and  the reason for this is actually twofold. First of all, we have basically the Mid-Atlantic  ridge that splits Iceland into two parts and, as it is, the ridges are basically  pulling the country in opposite directions and this makes room for magma to  actually travel towards the surface. So that's one reason. The other reason  is because Iceland happens to be right on top of a very massive  mantle plume and this mantle plume, or "hot spot" as it's sometimes referred to, actually is pushing magma  constantly up to the surface So these two things are the  reasons why Iceland is one   of the most volcanically active places on Earth. If you're interested in this thing, I would  like to point out that we have this book on sale in the Grapevine Store and you  can go and order it now if you like. Right where we're standing now, this is actually  probably about a 1,000 year old lava field and then right next to us, there's  a lava field that is one year old and the contrast is obvious. I mean, here we have  the lava, we have the beautiful moss all over and it's like seemingly  just smooth and like stones.   But, as you can see, the new  lava it's completely black it's very rough and it's absolutely not  safe to walk on. Be mindful of that. And just see how rough it is. It's still like,   it's not warm feeling so I  wouldn't burn myself even touch it, but I would absolutely advise against  actually walking on it. There can be   holes and there can be dangers looming underneath. But what's really interesting about  this, the eruption last year for   those of you if we if we should remind  ourselves a little bit how it worked   So, back in 2021 there was a series of  earthquakes that took place for about three weeks and it was a very concentrated seismic period  where there was thousands of earthquakes indicating that magma was Rising towards the  surface. And that's exactly what happened. And then the fissure opened up and the magma  came up and now the lava started flowing. But then about six months  later the eruption stopped. And then for about a year and everything was quiet  until last year, 2022, in August when suddenly for a brief amount of time there  was a lot of seismic activity again. Earthquakes were taking  place and, a few days later,   the crater over there opened up and  this lava field started coming out. It was a small eruption so  it was actually safe to walk   up to the area and just explore  at the wonders that is nature. It was absolutely fantastic and now what we're   seeing is that the seismic  activity has started again. Fagradalsfjall, which had actually been  dormant and sleeping for 6,000 years,   has definitely come back  to life – that's for sure. A little bit farther in the distance  on the slope there you can actually   see that there's lava from the 2021 eruption that was flowing down that slope and actually  right over there on the mountain top you can see the very top of the biggest crater. So what is basically happening is that the first  eruption was happening the farthest away from us. The eruption last year then  took place a little bit closer.   But now what we're looking at is actually that the sort of most concentration   of the earthquakes that we're  seeing is actually happening between where the lava flowed last year and   the mountain that we see there  in the distance called Keilir. So most of the seismic activity that's been  going on has been somewhere on that line. So speculation basically is that if it will  erupt again it may happen somewhere in this area. So let me actually explain what's going on.   So we are in the Reykjanes  peninsula and we are actually in an area where there's no magma chambers. So what basically is going on is  that when magma is travelling up to   the surface it's coming straight from the mantle and what basically happens is that  the magma is travelling up and   creating something that we call a magma intrusion or a dyke, if you will. And it's actually very distinctive  in shape. So what happens in this   magma intrusion is that it's very very very thin but it goes miles and miles, both lateral and  vertical, and it's a little bit like this paper. So basically what we have  is the inside of the crust,   we have basically an area that  looks a little bit like this that's just magma and then that's where all  the seismic activity is happening and then at some point   the magma may actually breach the surface  and travel all the way up and lava will start pouring over the surface again and this  is where it might happen. Right here. Somewhere between the previous lava  field and Keilir. Quite exciting. So even if you don't necessarily see a lot of  people here right now, the area actually is open But there is a level of uncertainty and   that basically means that the  authorities have warned that an eruption may take place at any given  time. So there's definitely a risk factor. And therefore if you really do want  to come here you absolutely can but you just have to pay attention to  risk factors and be really mindful of   how to react, you know, around volcanic eruptions And the thing is, the reason why the  authorities have actually kept the area open   is because they basically trust the Icelandic people to be the judge of  how to behave around an eruption site. And that's why, you know, it could be a  good idea to pay attention to the locals. We're in civil protection in Iceland we are all   about safety we recommend people  not to be at the area right now because we really don't know what is going  to happen. We think the eruption will be   at the area at any time now. So please do not go there. It is not safe.  It is not forbidden to walk at the area,   but we really recommend not to do it. One of the reasons it's dangerous to be there is  the gas. So if you're there you can smell the gas. So if you can, please try to, yeah, go  away, walk away and go as high as you can. When I was younger I was raised with a lot  of stories about volcanoes and eruptions and particularly how they basically  affected the people living in Iceland.   And that's always been an aspect that's fascinated me and so as I grew older  every chance there was to go to an eruption site and just see this kind of spectacle firsthand  I took.And so, you know, back in 2010 my husband and I we actually went to  the erupson site at Fimmvörðuháls. Oh,   it was amazing. It was so incredible. There was a lava fall, so just exchanged lava  with water with lava and you get what I mean. And it sparked the idea to actually create a  show where people would be able to experience   real flowing lava in a safe environment. So that's actually what we  did. We founded a company we opened up Lava Show first in Vík on the south coast   and then in Reykjavik. And we there have a  show where you get to experience real lava in a completely safe environment and  you get to learn a lot about how,   you know, the history of Icelandic volcanism it's a very educational show and  very connected to the culture. So what a day! It's been amazing  and thank you all for staying with   us. We are quite excited about the developments and we hope you are, too. Whatever will happen, we will definitely  report on it so don't miss anything. Stay tuned Oh wow did you feel that one
