2021 Semeru Eruption
An eruption of Mount Semeru, a volcano in the East Java province of the Indonesian island of Java, began on 4 December 2021. The eruption began after heavy precipitation caused the collapse of the lava dome at the summit. Pyroclastic flows and lahars damaged at least 5,205 homes and several public buildings. At least 69 people died, 104 more were injured, while more than five remain missing. Background Semeru is one of more than 100 active volcanoes in Indonesia. At 3,676 meters in elevation, it is the highest volcano on the island. The volcano is part of a chain of volcanic mountains stretching from northern Sumatra to the Lesser Sunda Islands. Volcanism in Indonesia is mainly associated with the offshore subduction of the Australian Plate beneath the Sunda Plate. The oldest record of an eruption was from 1818. Since then, major eruptions have occurred in 1941, 1942, 1945, 1946, 1947, 1950, 1951, 1952, 1953, 1954, 1955–1957, 1958, 1959, 1960, 1977, and 1978–1989. A minor ...

2021 Eruption Of La Soufrière
La Soufrière, a stratovolcano on the Caribbean island of Saint Vincent in Saint Vincent and the Grenadines, began an effusive eruption on 27 December 2020. On 9 April 2021 there was an explosive eruption, and the volcano "continued to erupt explosively" over the following days, with pyroclastic flows. The activity pattern of the eruption was comparable to that of the event that occurred in 1902, which had a Volcanic Explosivity Index (VEI) of 4. The volcano is known to have erupted 23 times in the last 4,000 years, and had been dormant since 1979. Evacuation of the inhabitants of the island began when the explosive eruptions started. Many countries, including islands in the region, and organisations provided relief and support. Services such as electricity and water were severely affected. Emitted ash and sulfur dioxide gas affected the population. The COVID-19 pandemic made evacuation more difficult, requiring usual COVID-19 precautions to avoid outbreaks. Effusive ph ...

La Soufrière (volcano)
La Soufrière or Soufrière Saint Vincent () is an active stratovolcano on the Caribbean island of Saint Vincent in Saint Vincent and the Grenadines. It is the highest peak in Saint Vincent, and has had five recorded explosive eruptions since 1718. The latest eruptive activity began on 27 December 2020 with the slow extrusion of a dome of lava, and culminated in a series of explosive events between 9 and 22 April 2021. Geography and structure At , La Soufrière is the highest peak on Saint Vincent as well as the highest point in Saint Vincent and the Grenadines."La Soufrière" on Peakbagger.com Retrieved 1 October 2011 Soufrière is a stratovolcano with a and is the ...

2021 Mount Nyiragongo Eruption
On 22 May 2021, Mount Nyiragongo in the Democratic Republic of the Congo began erupting. As of 25 May, 32 people died as a result of the eruption and 1,000 homes were destroyed. Background According to a Virunga National Park official, the eruption of Mount Nyiragongo is similar to the eruption in 2002, which caused the death of 250 people. In September 2020, Katcho Karume, director of the Goma Volcano Observatory, said that the lava lake had been rapidly filling, increasing the risk of an eruption in the next few years, though Karume also noted that an earthquake could trigger an eruption earlier. The Observatory had not been properly functioning for almost a year before the eruption, after the World Bank cut funding following allegations of corruption. The Observatory was unable to pay for an internet connection to connect remote monitors or for fuel to regularly transport staff to the observation points; staff manually downloaded data from memory cards during their few vis ...

Mount Nyiragongo
Mount Nyiragongo ( ) is an active stratovolcano with an elevation of in the Virunga Mountains associated with the Albertine Rift. It is located inside Virunga National Park, in the Democratic Republic of the Congo, about north of the town of Goma and Lake Kivu and just west of the border with Rwanda. The main crater is about wide and usually contains a lava lake. The crater presently has two distinct cooled lava benches within the crater walls – one at about and a lower one at about . Nyiragongo's lava lake has at times been the most voluminous known lava lake in recent history. The depth of the lava lake varies considerably. A maximum elevation of the lava lake was recorded at about prior to the January 1977 eruption – a lake depth of about . Following the January 2002 eruption, the lava lake was recorded at a low of about , or below the rim. The level has gradually risen since then. Nyiragongo and nearby Nyamuragira are together responsible for 40 per cent of Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amami Islands
The The name ''Amami-guntō'' was standardized on February 15, 2010. Prior to that, another name, ''Amami shotō'' (奄美諸島), was also used. is an archipelago in the Satsunan Islands, which is part of the Ryukyu Islands, and is southwest of Kyushu. Administratively, the group belongs to Kagoshima Prefecture, Japan. The Geospatial Information Authority of Japan and the Japan Coast Guard agreed on February 15, 2010, to use the name of for the Amami Islands. Prior to that, was also used. The name of Amami is probably cognate with , the goddess of creation in the Ryukyuan creation myth. Geography The Amami Islands are limestone islands of coralline origin and have a total area of approximately , of which constitute the city (''-shi'') of Amami, and constitute the district (''-gun'') of Oshima. The highest elevation is ''Yuwandake'' with a height of on Amami Ōshima. The climate is a humid subtropical climate ( Köppen climate classification ''Cfa'') with very warm summers ...

Submarine Volcano
Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation, known as mid-ocean ridges. The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth.Martin R. Speight, Peter A. Henderson, "Marine Ecology: Concepts and Applications", John Wiley & Sons, 2013. . Although most submarine volcanoes are located in the depths of seas and oceans, some also exist in shallow water, and these can discharge material into the atmosphere during an eruption. The total number of submarine volcanoes is estimated to be over 1 million (most are now extinct) of which some 75,000 rise more than 1 km above the seabed. Only 119 submarine volcanoes in Earth's oceans and seas are known to have erupted during the last 11,700 years. Hydrothermal vents, sites of abundant biological activity, are commonly found near submarine volcanoes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
