Roundup of Global Volcanic Activity:
Etna (Sicily, Italy): Relatively strong ash explosions continue to occur from the New SE crater. New activity started yesterday afternoon from the New SE crater. Several relatively intense explosive ash emissions were observed from the summit vent of the cone. They produced dense ash plumes rising about 200 m. More explosions occurred during the night, separated by intervals varying from 20 minutes to about 2 hours, during which strong degassing continued and the fumarolic area at the crater rim remained incandescent. The tremor showed a light increase during the night, but it is not clear at the moment, if this is already a precursor to yet another paroxysm.
Karangetang (Siau Island, Sangihe Islands, Indonesia): An eruption has occurred this morning. VAAC Darwin signaled a volcanic ash cloud reaching 14,000 ft (4.3 km) altitude and extending 25 nautical miles to the WNW. VSI maintains the volcano on yellow alert (since 2011).
