Papandayan volcano (Western Java, Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 10 August-16 August 2011 (New Activity / Unrest)
On 13 August CVGHM reported that based on seismicity, deformation, geochemistry, and visual observations, the Alert Level for Papandayan was raised to 3 (on a scale of 1-4). During 1 June-12 August sulfur plumes rose 20-75 m above the vents. During the same period, seismicity increased with several hundreds of earthquakes detected per month.

Papandayan volcano (Western Java, Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 9 April-15 April 2008 (New Activity / Unrest)
CVGHM reported that the seismic network recorded one volcanic tremor signal from Papandayan on 15 April. On 16 April, measurements of summit fumaroles revealed an increase in temperature and changes in water chemistry since 7 April. White plumes continued to rise to an altitude of 2.7 km (8,900 ft) a.s.l. and did not change. ... Read all

Papandayan volcano (Western Java, Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 9 January-15 January 2008 (Continuing Activity)
On 7 January, CVGHM lowered the Alert Level at Papandayan from 2 to 1 (on a scale of 1-4) due to a decrease in activity over approximately four months. Seismic events decreased in number after 2 August 2007, and earthquake tremor was not recorded since 14 November 2007. Data from deformation-monitoring instruments indicated deflation. ... Read all
