In the case of Pinatubo, the team discovered that the magma chamber took only 20 to 80 days to reactivate, versus the 500 years predicted by conventional theory. "When we increase volcanic emissions, which increases the baseline of sulfate aerosols, we decrease the effect that the human-made aerosols have on the climate by up to a factor of two.". While there are no active volcanoes in Greenland, scientists are confident a hot spot an area where heat from Earths mantle rises up to the surface as a thermal plume of buoyant rock existed long ago beneath Greenland because they can see the residual heat in Earths crust, Ivins says.

A small number of earthquakes began under Edgecumbe in 2020, but the cause was ambiguous until the deformation results were produced.
