Karangetang (also known as Api Siau) is a volcano on the north side of Siau Island off the coast of Sulawesi, Indonesia. The island covers 160 km2, and had 46,459 inhabitants in mid 2023.[2] [3] It is one of the most active volcanoes in Indonesia, having erupted 41 times since 1675. A pyroclastic flow in 1997 killed three people.[4]
In August 2007 an eruptive episode forced evacuations from nearby areas.[5]
On 9 June 2009 the Volcanological Survey of Indonesia raised the eruption alert status of Karangetang to Level Orange.[6]
On 6 August 2010 Karangetang again erupted, spewing lava and ash hundreds of meters into the air. Four villagers are missing.[7] [8]
On 11 March 2011, a few hours after an earthquake in Japan caused a Pacific-wide tsunami, Mount Karangetang again erupted. There were no reports of serious damage or casualties, though lava and hot gas clouds were emitted onto its slopes.[9]
On September 2, 2013, the volcano began erupting again. There was another spell of activity from November 2018 onwards. On 20 July 2019 a new eruption started, continuing as of October 2019. This was accompanied by effusion of lava.[10]
Dense white gas-and-steam plumes were visible from Karangetang on most days during 13-19 September, rising as high as 300 m. Seismicity during 1-7 September indicated lava from the SW side of Main Crater (S crater) continued to effuse but at a decreased rate, and that the number of earthquakes indicating avalanches had also decreased, according to Vulcanological Survey of Indonesia.
