Roundup of Global Volcanic Activity:
Etna (Sicily, Italy): A small swarm of earthquakes has occurred yesterday under the volcano’s eastern flank near the town of Milo. INGV Catania has recorded several quakes around magnitude 0.7-1.3 at depths between 5-9 km.
Pavlov (Alaska Peninsula, USA): Over the past two days, the eruptive activity at Pavlof has greatly declined and AVO reduced the Aviation Colour Code back to Yellow and the Volcano Alert Level to Advisory. Seismic tremor and small discrete explosions are no longer detected in seismic and pressure sensor data. Satellite observations show no evidence of elevated surface temperatures, volcanic gas, or ash emissions. There have been no visual observations from pilots or from webcam images of any eruptive activity since June 26.
