Stromboli volcano, Italy: activity 24-26 July 2019

Stromboli volcano, Italy: elevated activity 24-26 July 2019

Photographs taken by volcanologist Dr Ingrid Smet when she observed Stromboli's volcanic activity from 24 to 26 July 2019. During this time span, the volcano remained at a level of higher than usual activity with very frequent Strombolian explosions. Some of these were so strong that at night one could observe the glowing bombs from the village. The lava flows that occurred after the 3 July paroxysm were also still active on the upper parts of the western edge of the Sciara.

Looking up at the active crater terrace where the NE spatter cone has been destroyed in the 3 July 2019 paroxysm. Continuous strong degassing created fresh white deposits just below the edge of the terrace which are partially covered by recent overflows. The darker deposits in the bottom left part of the Sciara represent the previous lava flows, dating back to August 2014. (Photo: Ingrid)
