Laki (Icelandic pronunciation: [ˈlaːcɪ]) or Lakagígar ([ˈlaːkaˌciːɣar̥], Craters of Laki) is a volcanic fissure in the western part of Vatnajökull National Park, Iceland, not far from the volcanic fissure of Eldgjá and the small village of Kirkjubæjarklaustur. The fissure is properly referred to as Lakagígar, while Laki is a mountain that the fissure bisects. Lakagígar is part of a volcanic system centered on the volcano Grímsvötn and including the volcano Thordarhyrna. It lies between the glaciers of Mýrdalsjökull and Vatnajökull, in an area of fissures that run in a southwest to northeast direction. The system erupted violently over an eight-month period between June 1783 and February 1784 from the Laki fissure and the adjoining volcano Grímsvötn, pouring out an estimated 42 billion tons or 14 km3 (3.4 cu mi) of basalt lava and clouds of poisonous hydrofluoric acid and sulfur dioxide compounds that contaminated the soil, leading to the death of over 50% of Iceland's livestock population, and the destruction of the vast majority of all crops. This led to a famine which then killed approximately 69% of the island's human population. The lava flows also destroyed 21 villages. The Laki eruption and its aftermath caused a drop in global temperatures, as 120 million tons of sulfur dioxide was spewed into the Northern Hemisphere. This caused crop failures in Europe and may have caused droughts in North Africa and India.

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.
