Volcanic eruption prediction methods encompass quantitative and qualitative techniques aimed at forecasting the onset, magnitude, and style of eruptive activity by integrating multi-parameter monitoring and modeling. Core approaches include analysis of seismicity (e.g., volcano-tectonic and long-period events), ground deformation from GPS and InSAR, gas emission fluxes and compositions, thermal anomalies, and hydrological/geomorphic signals. These observational data feed into physics-based models of magma ascent, conduit flow, and stress evolution, as well as statistical and probabilistic frameworks such as Bayesian event trees and pattern-recognition algorithms. Prediction focuses on estimating conditional probabilities and time windows of unrest-to-eruption transitions, with uncertainty quantification central to civil protection decision-making.
Whakaari/White Island's sudden eruption in December 2019, which killed 22 people and severely injured 25 others, was New Zealand's deadliest volcanic disaster in recent history.
