Roundup of Global Volcanic Activity
Etna (Sicily, Italy): Etna remains highly restless. A peak in volcanic tremor occurred last night but with no visible changes in surface activity. Weak strombolian activity continues from the vent inside the Voragine summit craters.
Chirpoi (Kurile Islands, Russia): Passengers on board a Russian cruise ship documented the recent (and perhaps still ongoing) effusive / explosive eruption of Snow volcano. When passing the island in Oct 2015, lava flows were actively reaching the sea, creating spectacular littoral explosions.
Dukono (Halmahera): Mild strombolian activity and strong ash emissions were observed. Dukono was continuously emitting ash and producing mild strombolian activity from its two active vents with very loud rumblings and ash plumes up to 1 km. Harmonic tremor and earthquake swarms have been recorded more frequently, long with some local tectonic earthquakes triggered from the Pacific plate.
