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.
The massive 2018 eruption of Kīlauea Volcano on Hawai'i Island lasted for months, destroyed neighborhoods, and was associated with 60,000 earthquakes.

Currently, scientists struggle to forecast volcano eruption events, as no universally reliable, real-time eruption forecasting framework is available. Instead, researchers often rely on retrospective analysis to evaluate ...
Located on the island of Sicily, in Italy, Mount Etna is one of the world's most active volcanoes. Documentation of its many eruptions stretches back as far as 2,700 years ago, with the most recent occurring in June 2025. ...
A new study published in the Proceedings of the National Academy of Sciences provides scientists with a powerful new tool for monitoring and predicting tectonic activity deep beneath the seafloor at mid-ocean ridges—vast ...
