In a new study, published in the renowned journal Nature, experts write that the world must prepare for huge volcanic eruptions. They believe that more should be done both to anticipate, but also to be able to handle a potential disaster. The risk is actually greater than people think, write the authors. – Data collected over time suggests that the chance of a massive eruption, on a large scale, has a one-sixth chance of happening in the next hundred years. That’s what researcher Dr Lara Mani says. She is an expert on global risk. Requires better preparedness In January this year, the underwater volcano Hunga Tonga Hunga Ha’apai erupted. The explosion is the largest ever measured by instruments. Lara Mani believes a giant volcanic eruption could have the same consequences as a kilometer-wide asteroid hitting the Earth. – Such events will have similar consequences for the climate, but the chance of a volcanic disaster is hundreds of times greater. The researcher further says that money is “pumped” into the monitoring of asteroids and comets. But that there is a serious lack of funding and preparedness when it comes to volcanoes. – This must be changed. We completely underestimate the risk this has for our society, says the expert. The huge volcanic eruption on Tonga on January 15 had an explosive force equivalent to five to 30 megatons of TNT, according to the American space agency Nasa.

The old samples indicate that an eruption that is ten to a hundred times larger than the Tonga explosion occurs once every 625 years. This is twice as frequent as previously thought. – The last eruption of magnitude seven was in 1815 in Indonesia, says co-author Dr. Mike Cassidy. He is an expert on volcanoes. At the time, approximately 100,000 people died. And global temperatures dropped by a full degree on average. The consequences were, among other things, crop failure, famine, violent uprisings and epidemics, he says. – We now live in a world with many more inhabitants. Our complex global networks make us even more vulnerable in the event of a major outbreak. The volcano expert says the economic loss in the event of a colossal eruption could amount to many billions of kroner. He compares it to the corona pandemic. Now the researchers hope that the world will take action. Here, lava flows from a crater on Etna, Europe’s largest active volcano, near Catania, on the southern Italian island of Sicily.

She believes, like the authors of the study, that a major outbreak may occur. – As the last major global and climate-relevant eruption occurred in Pinatubo in 1991, we must expect that the next major one may come. She says that every year there are around 50 eruptions of various sizes in the world, but that it is difficult to predict the exact time of the next explosive eruption. Pinatubo is a volcano on Luzon, an island in the Philippines. The outbreak caused 700 people to die and 100,000 to become homeless. In addition, other aftereffects were seen, including on the climate, says Kr\u00fcger. – The volcanic haze gave reduced light. An abrupt cooling of the earth’s surface occurred, which also reduced precipitation globally. This should be done The authors behind the study have several suggestions for what should be done. Among other things, they believe that the risk must be mapped in a more accurate way. Around 97 areas in the world are to be classified as major eruptions, and according to the researchers, only a handful of these are known. This means there could be dozens of dangerous volcanoes scattered around the world with the potential for extreme destruction. – There may be recent outbreaks that we are not aware of due to a lack of research. Especially in neglected regions such as Southeast Asia. Volcanoes can lie dormant but still be capable of sudden and massive destruction, says Mike Cassidy. Monitoring also needs to be improved, say the experts. Only 27% of eruptions since 1950 have had a seismometer nearby. And only a third of that data has reportedly been fed into the global “volcanic unrest” database. – Volcanologists have been calling for a dedicated satellite for this work for over twenty years, says Lara Mani. The Icelandic volcano Eyjafjallaj\u00f6kull suddenly awakens in April 2010. The volcanic cloud reaches large parts of Europe’s airspace, and this causes air traffic to stand still for several days. Hence the term ash-fast. Photo: news \u2013 Should keep an eye on the big ones \u00d8ystein Nordgulen is a researcher and employee of the Geological Survey of Norway (NGU). He says it is well known that large volcanic eruptions have had a major impact on people’s lives and development. – The question is how big and long-lasting the effects of such a worldwide event will be on today’s society. Most people would agree that we should keep an eye on the known, large volcanoes that can give rise to “super-volcanic” events. This is already done today, for example in Yellowstone in the USA, explains Nordgulen. He believes that it will take a lot to be able to control or manipulate the large volcanic systems in the world, but that there should be broad support for monitoring and preparation. Nordgulen’s colleague at NGU, researcher Tom Heldal, also partially agrees with the researchers behind the study. – I believe that in some areas we are well prepared and others poorly. Tonga came as a total surprise. It tells us that volcanoes in any environment are very unpredictable. As history shows, this can lead to tsunamis, but also short-term global climate change. \u00d8ystein Nordgulen is a researcher and employee of the Geological Survey of Norway (NGU).
