Huaynaputina ( WY-nə-puu-TEE-nə; Spanish: [wajnapuˈtina]) is a volcano in a volcanic high plateau in southern Peru. Lying in the Central Volcanic Zone of the Andes, it was formed by the subduction of the oceanic Nazca Plate under the continental South American Plate. Huaynaputina is a large volcanic crater, lacking an identifiable mountain profile, with an outer stratovolcano and three younger volcanic vents within an amphitheatre-shaped structure that is either a former caldera or a remnant of glacial erosion. The volcano has erupted dacitic magma. In the Holocene, Huaynaputina has erupted several times, including on 19 February 1600 – the largest eruption ever recorded in South America – which continued with a series of events into March. Witnessed by people in the city of Arequipa, it killed at least 1,000–1,500 people in the region, wiped out vegetation, buried the surrounding area with 2 metres (7 ft) of volcanic rock and damaged infrastructure and economic resources. The eruption had a significant impact on Earth's climate, causing a volcanic winter: temperatures in the Northern Hemisphere decreased; cold waves hit parts of Europe, Asia and the Americas; and the climate disruption may have played a role in the onset of the Little Ice Age. Floods, famines, and social upheavals resulted. This eruption has been computed to measure 6 on the Volcanic Explosivity Index (VEI). The volcano has not erupted since 1600. There are fumaroles in the amphitheatre-shaped structure, and hot springs occur in the region, some of which have been associated with Huaynaputina. The volcano lies in a remote region where there is little human activity, but about 30,000 people live in the immediately surrounding area, and another one million in the Arequipa metropolitan area. If an eruption similar to the 1600 event were to occur, it would quite likely lead to a high death toll and cause substantial socioeconomic disruption. The Peruvian Geophysical Institute announced in 2017 that Huaynaputina would be monitored by the Southern Volcanological Observatory, and seismic observation began in 2019.

The Black Dragon fire, also known as the 1987 Daxing'anling wildfire (Chinese: 大兴安岭特大森林火灾) or the May 6 fire (Chinese: 5·6大火) was a major wildfire that began in the northeast Daxing'anling Prefecture, Heilongjiang, People's Republic of China on May 6, 1987. It also spread into the Soviet Union. The burning lasted almost a month, when it was finally stopped on June 2, 1987. The fire covered about 10,000 km2 (2,500,000 acres) of which 6,500 km2 (2,500 sq mi) was forest; it destroyed 7.3 million hectares (18 million acres) of forest, including one-sixth of China's entire timber reserves. About 266 people were wounded and 211 died in the fire leaving 50,000 homeless. It was one of the largest wildfires ever to occur, and the largest to strike China in over 300 years.
