Last night's seismic recording from Masaya volcano (MASN station, INETER)
Paluweh (north off Flores Island, Indonesia) produced a major vulcanian explosion shortly before midnight. Darwin VAAC reported an ash plume rising to 43,000 ft (about 13 km) altitude and extending 175 nautical miles to the south. Local press speaks about an explosion and ash rising 3 km. Ash fall has occurred in Flores, especially near the coast at 17 km downwind distance.
Current seismic signal from San Miguel (VSM station, SNET)
Lokon-Empung (North Sulawesi, Indonesia): Another relatively strong eruption occurred today. An ash column rising 3 km was observed after an explosion from the Tompulan crater at 14:09.
It seems that only larger explosions like this now make news entries in the Indonesian (and from there international) press. There are many more smaller ones occurring.
The head of the local volcano observatory, Farid Bima, was quoted in an article that explosions occur daily, and that yesterday alone, Lokon had 9 (nine) explosions.

Stromboli (Eolian Islands, Italy): Explosion signals on the seismograms appear to have becoming stronger again today, while Etna (Sicily, Italy) has stayed quiet, but for how long? If the rhythm of the recent eruptions remains, we could expect another one to be very soon. By coincidence, they all happened at night. So, if you're into watching volcanoes live, be sure to tune into webcams.volcanodiscovery.com/Etna (or go to Sicily, much better!)
There are no reported changes in activity at any of the Kamchatkan volcanoes. Fluid lava continues to erupt from Plosky Tolbachik volcano, accompanied by stable, relatively high tremor levels. Moderate seismicity suggests ongoing lava extrusion and dome building at Sheveluch and Kizimen.
Low to moderate seismicity accompanies occasional explosive activity from Karymski volcano. The strong seismicity from Tolbachik obscures the signals from Bezymianny, which also continues to slowly build a lava dome, as well as the rather weak current strombolian activity at the summit of Klyuchevskoi volcano. Gorely continues to show medium levels of tremor caused by fluid movements and strong degassing.
White Island (New Zealand): Tremor has remained constant and strong today, mixed with numerous hybrid earthquakes.
Iliamna (Cook Inlet (SW Alaska)): Earthquake activity remains slightly increased.
Mammoth Mountain (California, USA): Small earthquakes continue beneath and (mostly) immediately to the SE of Mammoth Mountain in the Sierra Nevada range.
Popocatépetl (Central Mexico): There are no changes in the mild activity of the volcano. There are about 2 weak emissions per hour and night-time glow is usually visible. Strong (SO2) degassing is visible again on satellite data.
Santa María / Santiaguito (Guatemala): Explosive activity has picked up again. There are frequent small to moderat ash emissions with plumes rising up to 1 km that drift SW and cause a constant light rain of ash in parts of Monte Claro and areas near Aldea San Marcos Palajunoj.
Fuego (Guatemala): The two lava flows advanced a bit and have now a length of about 300 m. Explosive activity has been weak in return during the report interval 1-2 Feb. There were only 5 small explosions with plumes rising 400 m registered.
In Nicaragua, volcanoes have been rather quiet recently. The tremor at San Cristobal volcano has ceased and activity is again low. Masaya has in turn some increased tremor activity.
Nearby San Miguel volcano in El Salvador continues to produce weak continuous tremor mixed with local and some regional earthquakes.
Galeras (Colombia): Small volcanic quakes and long period events continue, but seismic and surface activity generally remains low.
Nevado del Ruiz (Colombia): Seismic activity has been low recently with only occasional tiny quakes and tremor pulses. 2 regional earthquakes show up on the seismograms of today.

Etna (Sicily, Italy): After a day with ash emissions from New SE crater and occasionally from Bocca Nuova, another eruptive episode with strong strombolian activity occurred over night from both the New SE crater and Bocca Nuova. This is the 8th eruptive episode during 2013, but the first when both the New SE crater and Bocca Nuova were active at the same time. ... [more]
