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.

Tacloban ( tak-LOH-ban; Tagalog pronunciation: [tɐkˈloban]), officially the City of Tacloban (Waray: Syudad han Tacloban; Tagalog: Lungsod ng Tacloban), is a 1st class highly urbanized city in the Eastern Visayas region of the Philippines. The city is autonomous from the province of Leyte, although it serves as its provincial capital. According to the 2020 census, Tacloban has a population of 251,881, making it the most populous city in the Eastern Visayas. The city is located 360 miles (580 km) southeast from Manila. Tacloban City was briefly the capital of the Philippines under the Commonwealth Government, from 20 October 1944 to 27 February 1945. In an extensive survey conducted by the Asian Institute of Management Policy Center and released in July 2010, Tacloban City ranks as the fifth most competitive city in the Philippines, and second in the emerging cities category. On 8 November 2013, the city was largely destroyed by Typhoon Haiyan, having previously suffered similar destruction and loss of life in 1897 and 1912. On 17 January 2015, Pope Francis visited Tacloban during his Papal Visit to the Philippines and held a mass at Barangay San Jose, and later he led mass of 30,000 people in front of the airport.
