“In Iceland, the eruption of the Laki volcano tore the earth apart and created 130 volcanoes in a line. They began spewing ash and dangerous gases. The area covered by lava reached 600 square kilometres. The sulphur compounds that entered the atmosphere blocked the sun’s radiation. Britain then experienced a so-called ‘sand summer’, when sand and ash rained down, and the whole of Europe cooled rapidly. The summer of 1783 was the coldest in 500 years, food shortages led to discontent and, among other things, the start of the Great French Revolution.”
Geologists say volcanoes whisper. It refers to the moment just before an eruption, before the volcano screams and spews fire and smoke. Just two centuries ago, the eruption of an Indonesian volcano took the lives of 100,000 people, and the story of Pompeii buried under several metres of lava is still taught today. Even so, people grow the most delicious wines at the foot of volcanoes and build cities like something out of a Star Wars movie. When will one of the Czech volcanoes erupt? Can the instruments predict when it’s time to get the camera out and when to put your feet up? What breakthrough happened in the Komorní hůrka volcano and where to find the volcano in Brno? Lukáš Krmíček, a geologist from the Faculty of Civil Engineering at the BUT, talked about all this and much more.
