Published Sea levels influence eruptions on volcanic island
(via sciencedaily.com) The rise and fall of sea levels influence the likelihood of volcanic eruptions on the Greek island of Santorini, new research has discovered. Analyzing the timings of eruptions over hundreds of thousands of years, the researchers found that a 40 meter fall in sea level is a crucial point beyond which eruptions are more likely to occur. The findings could have implications for millions of people living on volcanic islands around the world.
Published Giant friction experiment at Kilauea volcano
(via sciencedaily.com) A new analysis of the 2018 collapse of Kilauea volcano's caldera helps to confirm the reigning scientific paradigm for how friction works on earthquake faults. The model quantifies the conditions necessary to initiate the kind of caldera collapse that sustains big, damaging eruptions of basaltic volcanoes like Kilauea and could help to inform forecasting and mitigation.
Published Huge volcanic eruption disrupted climate but not human evolution
(via sciencedaily.com) A massive volcanic eruption in Indonesia about 74,000 years ago likely caused severe climate disruption in many areas of the globe, but early human populations were sheltered from the worst effects, according to a new study.
Published Supervolcano fed from Earth's mantle caused crustal plates to rotate
(via sciencedaily.com) The plates of the Earth's crust perform complicated movements that can be attributed to quite simple mechanisms. That is the short version of the explanation of a rift that began to tear the world apart over a length of several thousand kilometers 105 million years ago.
Published To predict underwater volcano eruptions, scientist looks at images from space
(via sciencedaily.com) Original source A new study monitored satellite images to obtain sea discoloration data as a novel indicator in detecting if an underwater volcano's eruption is imminent.
Published Like a molten pancake
(via sciencedaily.com) Original source Why magma flowed along a curved pathway during the 2018 eruption of a Galapagos volcano is explained by a new model.
