Explosion from the New SE crater
Etna (Sicily, Italy): Relatively strong ash explosions continue to occur from the New SE crater. At the same time, the tremor signal is rising - maybe we're about to witness the start of a new paroxysm?

New activity has 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).

Stromboli (Eolian Islands, Italy): No significant changes have occurred recently. The seismic signal shows medium tremor levels with phases of medium to high values, and there are frequent (about 10 per hour), sometimes quite powerful strombolian explosions from the various active vents. Small amounts of lava sometimes overspill from the NE vent. ... [more]

Tjörnes Fracture Zone (North of Iceland): The powerful earthquake swarm that started a week ago continues, but at reduced intensity compared to 2 April when the large magnitude 5.4 quake struck. Each day, hundreds of earthquakes have been occurring (more than 200 > magnitude 2 during the past 2 days). ... [more]
