Abstract Pre‐eruptive signals at the crater lake‐bearing Mt. Ruapehu (New Zealand) are either absent or hard to identify. Here, we report on geophysical anomalies arising from hydrothermal unrest (HTU) and magmatic unrest (MU) using multiphysics

Key points: • Detectable self-potential and deformation anomalies result from poroelastic responses of volcanicaquifers by subsurface pressurization • Self-potential amplitudes and their polarity are sensitive to magmatic stressing and pressure s
