Volcanic activity world-wide 19-20 December 2012: Tungurahua, Tobachik, Paluweh, Popocatépetl, Pacaya, Ulawun, Manam, White Island

Thursday Dec 20, 2012 14:13 PM | BY: T

The eruption of Tungurahua volcano in Ecuador is becoming increasingly dangerous. This morning, a phase of strong activity occurred with explosions every 5 minutes and another pyroclastic flow was observed going through the Cusua ravine.
During the past days, ash emissions and frequent explosions produced ash columns rising 2-2.5 km. THe explosions ejected incandescent lava up to about 400 m above the crater and produce loud cannon-fire noises and roars that can be heard in all towns near the volcano and sometimes cause buildings vibrate.

The eruption of Plosky Tolbachik volcano in Kamchatka continues with strong tremor and vigorous lava emission.

Lava has been recently also seen at Klyuchevskoi volcano, that still has strombolian activity in its summit crater, and sporadic weak explosions continue to occur from Karymski volcano in Kamchatka. Activity at Kizimen volcano instead has recently decreased a lot; its lava dome seems to have stopped growing (for now).

Popocatépetl volcano in Mexico: After increasing to 5 weak steam and sometimes ash emissions per hour during 17-18 Dec, the rate has dropped to about 3 per hour during 18-19 Dec. Glow remains visible at night.

On the morning of 18 December, Pacaya volcano in Guatemala had 3 small explosions of gas-and-ash that left a new small crater. Since then, the volcano has remained calm, but this is the volcano's first surface activity since late 2010, and could indicate its re-awakening.

One of our correspondents in Indonesia reports that the new lava dome of Paluweh volcano now produces pyroclastic flows that reach the sea on the south side. Vegetation in the surroundings of the lava dome has all been killed.

Ash emissions from Ulawun volcano in Papua New Guinea ceased on 11 December, the Rabaul Volcano Observatory reported to USGS. During the past days, only steaming was observed.

As the recent Smithsonian / USGS Weekly Volcanic Activity Report mentions, Manam volcano has been having mild strombolian activity and producing a small lava from two vents located on the upper slopes of the SE valley during 8-14 Dec.

At White Island volcano, GNS Science volcanologists found no changes to the new lava dome during the past 10 days when they became aware of it. Temperature measurements of the dome and surrounding lakes revealed nothing unusual. Seismically, a constant tremor signal continues to be visible and there a slightly rising tendency during the past weeks can be noted.

Following the first explosion on Friday, Tungurahua volcano in Ecuador has entered a new violent phase of activity. Numerous explosions have occurred with ash rising up to 8 km above the crater. So far small pyroclastic flows have descended the flanks and partly heavy ash fall has been affecting nearby areas. Combined with rainfall the fresh ash deposits have a dangerous potential to generate lahars in drainages surrounding the volcano. ... [more]

The eruption from Tolbachik volcano in Kamchatka continues with lava fountains at the lower vent feeding very active lava flows, but KVERT noted that tremor levels were fluctuating. This could suggest that the magma supply has become less steady and the eruption might be approaching an end. Ash plumes from the eruption rose to up to 15,000 ft (4.5 km) altitude and are visible on satellite images. ... [more]

The eruption from Tolbachik volcano in Kamchatka continues. An article from the Ria Novosti news agency said that according to Russian seismologists, Tolbachik has been erupting a record of 1,200 tonnes or about 400 cubic meters of basaltic lava per second. If this number if correct, the current effusion rate would be significantly larger than the during the Great Tolbachik Fissure Eruption in 1975, when the effusion rate was about 40 m3/s on average. ...
