Mount Papandayan is a complex stratovolcano, located in Garut Regency, to the southeast of the city of Bandung in West Java, Indonesia. It is about 15 km to the southwest of the town of Garut. At the summit, there are four large craters which contain active fumarole fields. An eruption in 1772 caused the northeast flank to collapse producing a catastrophic debris avalanche that destroyed 40 villages and killed nearly 3,000 people. The eruption truncated the volcano into a broad shape with two peaks and a flat area 1.1 km wide with Alun-Alun crater in the middle, making the mountain appear as a twin volcano; one of the peaks is called Papandayan and the other Mount Puntang.Since 1772, only small phreatic eruptions were recorded before an explosive eruption that began in November 2002. More recently, the volcano has been quite active. On 13 August 2011 the volcano's early warning status was lifted from Level II, 'Vigilant' (Indonesian: Waspada) to Level III, 'Alert' (Siaga) following the swarm of long-period events, the increase of volcano tectonic earthquake rate, and an extremely high percentage (100%) of measured carbon dioxide gas in the ground at the summit crater. People, including tourists, were urged to remain at least 2 kilometers (1.2 mi) from the yellow craters on the 2,665-meter (8,743-foot) Mount Papandayan. On Friday 2 September 2011, the Indonesian Volcanology and Geophysical Disaster Mitigation Center reported that numerous shallow volcanic earthquakes had been recorded along with other indications of volcanic activity. A spokesperson for the Indonesian National Disaster Management Agency noted that if Mt Papandayan erupted, over 170,000 people living in five nearby subdistricts (kecamatan) and in twenty villages could be affected. Of the people likely to be affected, it was expected that perhaps as many as 11,500 people might need to be evacuated.

On 28 September 2018, a shallow, large earthquake struck in the neck of the Minahasa Peninsula, Indonesia, with its epicentre located in the mountainous Donggala Regency, Central Sulawesi. The magnitude 7.5 quake was located 70 km (43 mi) away from the provincial capital Palu and was felt as far away as Samarinda on East Kalimantan and also in Tawau, Malaysia. This event was preceded by a sequence of foreshocks, the largest of which was a magnitude 6.1 tremor that occurred earlier that day.Following the mainshock, a tsunami alert was issued for the nearby Makassar Strait. A localised tsunami struck Palu, sweeping shore-lying houses and buildings on its way. The combined effects of the earthquake and tsunami led to the deaths of an estimated 4,340 people. This makes it the deadliest earthquake to strike the country since the 2006 Yogyakarta earthquake, as well as the deadliest earthquake worldwide in 2018, surpassing the previous earthquake that struck Lombok nearly 2 months earlier, killing more than 500. The Indonesian Agency for Meteorology, Climatology and Geophysics (BMKG) confirmed that a tsunami had been triggered, with its height reaching an estimated maximum of 4 to 7 metres (13 to 23 ft), striking the settlements of Palu, Donggala and Mamuju along its path.The earthquake caused major soil liquefaction in areas in and around Palu. In two locations this led to mudflows in which many buildings became submerged causing hundreds of deaths with many more missing. The liquefaction was considered to be the largest in the world and was deemed as rare.
