Implications of Thermal Weakening and Magma Compressibility for Volcano Monitoring
Published in Journal of Geophiscal Research: Solid Earth, 2026
- 3D, compressible, nonlinear viscoelastic, numerical models of magma ascent, emplacement, and surface deformation
- Thermally weakened crust limits reservoir overpressure but deforms more than elastic crust with a net uplift reduction of several percent
- Magma compressibility results in overpressure reduction leading to a manyfold underestimation of intrusion volumes in young systems
