WFS News: Chemical tipping point of magma determines explosive potential of volcanoes

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Volcanic eruptions are the most spectacular expression of the processes acting in the interior of any active planet. Effusive eruptions consist of a gentle and steady flow of lava on the surface, while explosive eruptions are violent phenomena that can eject hot materials up to several kilometres into […]

Deep magma reservoirs are key to volcanic super-eruptions!

A new study shows the importance of large reservoirs in creating Earth’s most powerful volcanic eruptions and explains why they are so rare.

Earthquakes due to volcanic pressure : A warning signal of Volcanic eruptions

Source: Wiley New research in Geophysical Research Letters examines earthquake swarms caused by mounting volcanic pressure which may signal an imminent eruption. The research team studied Augustine Volcano in Alaska which erupted in 2006 and found that precursory earthquakes were caused by a block in the lava flow. 36 hours before the first magmatic explosions, […]
