Quantification of Volcano Deformation Caused by Volatile Accumulation and Release

Published in Geophysical Research Letters, 2022

  • Exsolving volatiles accumulate at the roof of a magma storage zone and contribute to surface deformation through buoyancy forces
  • 3D numerical models show that surface deformation is a function of the volatiles volume, density and depth as well as crustal rigidity
  • Volatile release during eruption can cause syn-eruptive subsidence of a few cm, which is 20% of the observed signal at Calbuco in 2015
