Karangetang volcano (Api Siau island, Indonesia): short-lived eruption 19-21 July
Monday Jul 28, 2014 15:56 PM | DOOR: T
An comparably small eruption occurred last week at the volcano. Incandescent lava avalanches were reported to descend from the summit lava dome to the SE, towards the area of Batu Awang, during 19-21 July.

It seems to have been a short-lived and relatively small event that did not form the feared pyroclastic flows (which Karangetang is notorious for): avalanches of gas-rich fresh lava that detaches from the dome and/or lava flows and turns into devastating hot turbulent flows that can reach many kilometers distance.
A thermal hot spot visible on MODIS data also suggested that fresh lava was present at the summit dome and on the flanks. The signal disappeared during the past days and no more news about volcanic activity were found.
VSI keeps the alert level of the volcano at Siaga ("alert") (3 on a scale of 1-4).

A new eruption could be underway at the volcano. VSI raised the alert to 3 (Siaga, alert) on a scale of 1-4, following the observation of incandescent lava at the summit and glowing rockfalls on the eastern side into the Batuawang ravine. Strong degassing generates a plume rising up to 500 m. ... [meer...]

VSI has decreased the alert level from 3 (Siaga, Alert) (since 8 August 2011) back to 2 (Waspada, watch). No lava emissions/ejections have been observed since 7 July and seismic actity has been decreasing over the past weeks. No hot spot is visible on satellite imagery. [meer...]

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). According to a news article, pahoehoe lava flows traveled 150 m and rock avalanches traveled 2 km down the flanks on that same day. [meer...]

Karangetang volcano (Siau Island, Sangihe Islands, Indonesia) activity update: hot spot visible at the summit
Wednesday, Jan 02, 2013
Thermal anomalies are becoming more frequent at Karangetang since mid December after being absent during the month before. No ash emissions have been observed, but it is likely that the volcano has started to produce some minor activity at the summit dome. [meer...]
