Samuel J. Mitchell is a British volcanologist at the University of Bristol in the United Kingdom.


  • At the recent La Palma eruption in the Canary Islands, we had a classic signal that something's going to happen (on its volcano). There was a scattering of earthquakes slowly moving up towards the surface to a particular spot. There also could be gas emissions, or increased temperatures of surface water, or the ground inflating slowly­ – these things can be detected by satellite. But most of the data that serve to warn scientists of an impending eruption are collected by instruments around the volcano. (However) Gathering that data is very difficult in the case of submarine systems (2022 Tonga volcano eruption case).
