The 1988–1989 North American drought ranks among the worst episodes of drought in the United States. This multi-year drought began in most areas in 1988 and continued into 1989 and 1990 (in certain areas). The drought caused $60 billion in damage ($131 billion 2021 USD) in United States dollars, adjusting for inflation). The drought occasioned some of the worst blowing-dust events since 1977 or the 1930s in many locations in the Midwestern United States, including a protracted dust storm, which closed schools in South Dakota in late February 1988. During the spring, several weather stations set records for the lowest monthly total precipitation and the longest interval between measurable precipitation, for example, 55 days in a row without precipitation in Milwaukee. During the summer, two record-setting heatwaves developed, similar to those of 1934 and 1936. The concurrent heat waves killed 4,800 to 17,000 people in the United States. During the summer of 1988, the drought led to many wildfires in forested western North America, including the Yellowstone fires of 1988. At its peak, the drought covered 45% of the United States. While covering less area than the Dust Bowl, which covered 70% of the United States, the drought of 1988 ranks as not only the costliest drought in United States history but also one of the costliest natural disasters in United States history. In Canada, drought-related losses added to $1.8 billion (1988 Canadian dollars).

Kīlauea (US: KIL-ə-WAY-ə, Hawaiian: [kiːlɐwˈwɛjə]) is an active shield volcano in the Hawaiian Islands. Historically, it is the most active of the five volcanoes that together form the Big Island of Hawaiʻi. Located along the southeastern shore of the island, the volcano is between 210,000 and 280,000 years old and emerged above sea level about 100,000 years ago. Its most recent eruption began on September 29, 2021. It is the second-youngest product of the Hawaiian hotspot and the current eruptive center of the Hawaiian–Emperor seamount chain. Because it lacks topographic prominence and its activities historically coincided with those of Mauna Loa, Kīlauea was once thought to be a satellite of its much larger neighbor. Structurally, Kīlauea has a large, fairly recently formed caldera at its summit and two active rift zones, one extending 125 km (78 mi) east and the other 35 km (22 mi) west, as an active fault of unknown depth moving vertically an average of 2 to 20 mm (0.1 to 0.8 in) per year. Between 2008 and 2018, Halemaʻumaʻu, a pit crater in the volcano's summit caldera, hosted an active lava lake. Kīlauea also erupted nearly continuously from vents on its eastern rift zone between January 1983 and April 2018, causing considerable property damage, including the destruction of the towns of Kalapana and Kaimū along with the community's renowned black sand beach, in 1990. Beginning in May 2018, activity shifted further downrift from the summit to the Puna district, during which lava erupted from two dozen vents. The eruption saw vigorous eruptive lava fountains that sent destructive rivers of molten rock into the ocean in three places. The eruption destroyed Hawaii's largest natural freshwater lake, covered substantial portions of Leilani Estates and Lanipuna Gardens, and completely inundated the communities of Kapoho, Vacationland Hawaii, and most of the Kapoho Beach Lots. Lava also filled Kapoho Bay and extended new land nearly a mile into the sea. The County of Hawaii reported that 716 dwellings were destroyed by lava. Concurrent with the activity in Puna, the lava lake within Halemaʻumaʻu drained and a series of explosive collapse events occurred at the volcano's summit, with at least one explosion emitting ash 30,000 feet (9,100 m) into the air. This activity prompted a months-long closure of the Kīlauea section of Hawaii Volcanoes National Park. The eruption ended in September 2018. After more than two years of quiescence, Kīlauea erupted again between December 2020 and May 2021 within Halemaʻumaʻu crater, where lava erupted from several vents boiled off a water lake that had been growing within the crater for more than a year, replacing it with a lava lake 229 metres (751 ft) deep.A new eruption began on September 29, 2021, when several vents began to erupt lava within Halemaʻumaʻu.
