Tangkuban Parahu volcano (Western Java, Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 13 March-19 March 2013 (New Activity / Unrest)

CVGHM reported that phreatic eruptions from Tangkubanparahu's Ratu Crater occurred on 28 February and during 4-6 March, and generated ash plumes that rose up to 100 m above the crater. Sulfur dioxide emissions increased to a high level on 24 February and then decreased through 3 March. Sulfur dioxide emissions again increased during 5-9 March; CVGHM speculated that the increase was due to an enlargement of the eruptive vent, which had grown to a diameter of 20 m.
Gas emissions decreased abruptly on 10 March and emission sounds stopped.

Seismicity had significantly increased on 22 February, marked by a growing number of daily events. A significant decrease was detected on 9 March. Deflation was detected from 24 February through early March, but was then stable during 7-14 March.
On 18 March the Alert Level was lowered to 1 (on a scale of 1-4).
