What caused the Santa Maria volcano to erupt in 2013?
The cause of the eruption was likely the accumulation of pressurized magma and gas under the dome composed of viscous (solid) lava. The pyroclastic flows affected mainly the south, southeast and NNE sides. Bombs from explosive activity were ejected to distances of 500 m.

What happens if u touch lava?
Lava won’t kill you if it briefly touches you. You would get a nasty burn, but unless you fell in and couldn’t get out, you wouldn’t die. With prolonged contact, the amount of lava “coverage” and the length of time it was in contact with your skin would be important factors in how severe your injuries would be!
What would happen if Taupo erupted?
“If Taupo were to erupt, we would expect to see major ground deformation and thousands of earthquakes, not hundreds,” Jolly says. White Island’s 2000 eruption followed a long period of activity and is one of “a couple” of eruptions Jolly has seen. Even that eruption, though, was “effectively a burp”, she says.
How many times has the Shiveluch volcano erupted?
Shiveluch has had over 60 large explosive eruptions during the past 10,000 years. Catastrophic eruptions took place in 1854 and 1956, when a large part of the lava dome collapsed and created a devastating debris avalanche.

How is the active lava dome at sheveluch?
The active lava dome at Sheveluch seen from the SW on 31 October 2020 with the rock fracturing due to new lava extrusion. The whaleback lava dome (center), at the top of the larger lava dome in the foreground, is brown with a smoother appearance in this photo and exhibits near-vertical fractures. Courtesy of Yu.
