Although most of Earth’s lava erupts beneath the oceans, submarine volcanoes are comparatively understudied, but a new review of submarine volcano seismoacoustics provides a framework for future work.
A global study suggests that volcanic eruption forecasting and detection may be improved by examining earthquake mechanisms and clustering in combination with individual volcano properties.
Satellite data have revealed that ground radiant temperatures around volcanoes rose in the years leading up to eruptions. The observation may help in forecasting future volcanic activity.
Impact and turbulence models for river tremor are adapted and combined into a model that predicts the amplitude and frequency content of volcanic eruption tremor.
More than 70 passive sensors on Mount Etna have captured the first radon measurements in volcanic plumes and show that radon could affect people around volcanoes.
Offshore observations by cabled ocean-bottom pressure recorders have revealed details of the 2015 eruption of Axial Seamount submarine volcano in the Pacific Ocean.
The 1980 eruption of Mount St. Helens influenced scientists who witnessed the event and spurred a new era in physical volcanology.
A machine learning algorithm automatically detects telltale signs of volcanic unrest.
Researchers used a combination of ground and space-based measures to look for warning signs for the flank collapse at Anak Krakatau in 2018, which triggered a tsunami that killed hundreds.
Little seismic unrest preceded the 2014 eruption of a stratovolcano in Indonesia, which suggests that the eruption was kick-started internally by volatile-triggered overpressure.
