Papandayan volcano (Western Java, Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 24 August-30 August 2011 (New Activity / Unrest)

Wed, 24 Aug 2011, 06:00
06:00 AM | BY: VN
On 26 August CVGHM reported that Papandayan showed minor to no changes in recent seismicity, deformation, geochemistry, and visual observations; therefore the Alert Level remained at 3 (on a scale of 1-4). Seismicity remained high, but stable, and was dominated by shallow volcanic earthquakes. Deformation measurements showed no change, and water temperatures in multiple fumarolic areas and lakes remained relatively unchanged.
Sulfur dioxide gas emissions decreased from 8 tons per day on 12 August to 6 tons per day on 23 August. Carbon dioxide in the soil at a 1 m depth in multiple areas did not increase. Visitors and residents were advised not to venture within 2 km of the active crater.
