Sequence of strong explosions at Stromboli volcano, Italy

An explosive sequence at the Stromboli volcano in Italy on January 30, 2023, caused the launch of coarse pyroclastic material at several hundred meters in height and produced an ash cloud that quickly dispersed southward.

Increased seismicity at Lascar volcano, Alert Level raised to Orange, Chile

Increased seismicity at Lascar volcano, Alert Level raised to Orange, Chile

Seismic activity around Chile’s Lascar volcano has increased over the past 2 days, causing Sernageomin to raise its Alert Level to Orange. The security perimeter around the crater was expanded to 10 km (6.2 miles), with the community urged to avoid unnecessary exposure to potential dangers. The seismicity is primarily linked to fluid dynamics within the volcanic system, which could be a result of the destabilization of a remnant magmatic body. This activity could lead to explosive events, potentially causing ashfall in the area.

Study reveals magma chamber at submarine Kolumbo volcano near Santorini, Greece poses a serious threat

Study reveals magma chamber at submarine Kolumbo volcano near Santorini, Greece poses a serious threat

A new study published in AGU’s Geochemistry, Geophysics, Geosystems has revealed the existence of a magma chamber beneath the Kolumbo volcano, located near Santorini, Greece. Using a high-resolution technology called full-waveform inversion, the study found that the magma chamber poses a serious hazard as it could produce a highly explosive, tsunamigenic eruption in the near future.
