Mount Slamet (Indonesian: Gunung Slamet) is an active stratovolcano in the Purbalingga Regency of Central Java, Indonesia. It has a cluster of around three dozen cinder cones on the lower southeast-northeast flanks and a single cinder cone on the western flank. The volcano is composed of two overlapping edifices. Four craters are found at the summit. Mount Slamet is a mountain with the coldest average temperature on the island of Java and one of the areas with the highest annual rainfall in Indonesia, namely 8,134.00 millimeters (mm) per year.[2]
Historical eruptions have been recorded since the eighteenth century,[1] with its most recent events being in 2009 and 2014. Its summit is Central Java's highest point.
Mount Slamet has had a total of 42 confirmed eruptions as of 18 September 2014.[1] The earliest recorded eruption was 11 August to 12 August 1772.[1]
Mount Slamet erupted again Wednesday, September 18, 2014 after four years of remaining quiet. The volcano, dormant since 2009, began erupting again in late August 2014 prompting authorities to raise alert levels in the area. While the eruption was not considered to be a large one, a nearby forest was razed and authorities blocked off a 2.5 mile radius in case of increased activity. Residents otherwise remained calm.
