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.
Temperature measurements in the Manuk thermal area indicated a relative increase from 29 June to 12 August and deformation measurements indicated inflation from 4 July to 10 August. Visitors and residents were not to venture within 2 km of the active crater.
