Mount Fuji is an active stratovolcano located on the Japanese island of Honshu, with a summit elevation of 3,776.24 m. It is the tallest mountain in Japan, the second-highest volcano located on an island in Asia, and seventh-highest peak of an island on Earth. Mount Fuji last erupted from 1707 to 1708. The mountain is located about 100 km (62 mi) southwest of Tokyo and is visible from the Japanese capital on clear days. Mount Fuji's exceptionally symmetrical cone, which is covered in snow for about five months of the year, is commonly used as a cultural icon of Japan and is frequently depicted in art and photography, as well as visited by sightseers, hikers and mountain climbers.
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and solidifies before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high to intermediate levels of silica, with lesser amounts of less viscous mafic magma. Extensive felsic lava flows are uncommon, but have traveled as far as 15 km (9 mi).
The Ring of Fire is a tectonic belt of volcanoes and earthquakes.
Mount Nyiragongo is an active stratovolcano with an elevation of 3,470 m (11,385 ft) in the Virunga Mountains associated with the Albertine Rift. It is located inside Virunga National Park, in the Democratic Republic of the Congo, about 12 km (7.5 mi) north of the town of Goma and Lake Kivu and just west of the border with Rwanda. The main crater is about two kilometres (1 mi) wide and usually contains a lava lake. The crater presently has two distinct cooled lava benches within the crater walls – one at about 3,175 m (10,417 ft) and a lower one at about 2,975 m (9,760 ft).
The Virunga Mountains are a chain of volcanoes in East Africa, in the area where Rwanda, the Democratic Republic of the Congo (DRC), and Uganda meet. The mountain range is a branch of the Albertine Rift Mountains, which border the western branch of the East African Rift. They are located between Lake Edward and Lake Kivu. The name "Virunga" is an English version of the Kinyarwanda word ibirunga, which means "volcanoes".
Nyamuragira, also known as Nyamulagira, is an active shield volcano in the Virunga Mountains of the Democratic Republic of the Congo, situated about 25 kilometres (16 mi) north of Lake Kivu. The name is derived from the Kinyarwanda Bantu verb Kuragira nyamu, meaning to herd animals; nyamu means animal or cows.
Umnak is one of the Fox Islands of the Aleutian Islands. With 686.01 square miles (1,776.76 km2) of land area, it is the third largest island in the Aleutian archipelago and the 19th largest island in the United States. The island is home to a large volcanic caldera on Mount Okmok and the only field of geysers in Alaska. It is separated from Unalaska Island by Umnak Pass. In 2000, Umnak was permanently inhabited by only 39 people and by 2010, around 18, placing the settlement of Nikolski in difficulty and its school was closed.
Mount Asama is an active complex volcano in central Honshū, the main island of Japan. The volcano is the most active on Honshū. The Japan Meteorological Agency classifies Mount Asama as rank A. It stands 2,568 metres (8,425 ft) above sea level on the border of Gunma and Nagano prefectures. It is included in 100 Famous Japanese Mountains.
Goma is the capital and largest city of the North Kivu Province in the eastern region of the Democratic Republic of the Congo (DRC). It is located on the northern shore of Lake Kivu, next to the Rwandan city of Gisenyi. It shares its borders with Bukumu Chiefdom to the north, Rwanda to the east, Masisi Territory to the west, and is flanked by Lake Kivu to the south. The city lies in the Albertine Rift, the western branch of the East African Rift System, and is only 13–18 km (8.1–11.2 mi) south of the active Nyiragongo Volcano. With an approximate area of 75.72 square kilometers, the city has an estimated population of nearly 2 million people according to the 2022 census, while the 1984 estimate placed the number at 80,000.
Mount Takahe is a 3,460-metre-high (11,350 ft) snow-covered shield volcano in Marie Byrd Land, Antarctica, 200 kilometres (120 mi) from the Amundsen Sea. It is a c. 30-kilometre-wide (19 mi) mountain with parasitic vents and a caldera up to 8 kilometres (5 mi) wide. Most of the volcano is formed by trachytic lava flows, but hyaloclastite is also found. Snow, ice, and glaciers cover most of Mount Takahe. With a volume of 780 km3 (200 cu mi), it is a massive volcano; the parts of the edifice that are buried underneath the West Antarctic Ice Sheet are probably even larger. It is part of the West Antarctic Rift System along with eighteen other known volcanoes.
Mount Rinjani is an active volcano in Indonesia on the island of Lombok. Administratively the mountain is in the Regency of North Lombok, West Nusa Tenggara. It rises to 3,726 metres (12,224 ft), making it the second highest volcano in Indonesia. It is also the highest point in the Indonesian province of West Nusa Tenggara.
The Decade Volcanoes are 16 volcanoes identified by the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) as being worthy of particular study in light of their history of large, destructive eruptions and proximity to densely populated areas. The Decade Volcanoes project encourages studies and public-awareness activities at these volcanoes, with the aim of achieving a better understanding of the volcanoes and the dangers they present, and thus being able to reduce the severity of natural disasters.
Lava lakes are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. The term is used to describe both lava lakes that are wholly or partly molten and those that are solidified.
Sake is a town in the Democratic Republic of the Congo in the eastern province of North Kivu. It is located at the northwestern extremity of Lake Kivu, 25 km (15 mi) west-northwest of Goma on National Road No. 2, at the edge of the volcanic lava plains in the bottom of the Western Rift Valley, at an elevation of about 1500 m. The western escarpment of the rift valley rises to 800 m above Sake.
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from 800 to 1,200 °C. The volcanic rock resulting from subsequent cooling is also often called lava.
Mount Mikeno is an extinct volcanic mountain located in the Democratic Republic of the Congo section of the Virunga Mountains along with Mount Nyiragongo, Mount Nyamuragira, Mount Karisimbi, Mount Bisoke and Mount Sabyinyo. At 4,437 metres (14,557 ft) Mount Mikeno is the second highest peak in the Virunga Mountains after Karisimbi, and the 13th highest in Africa. Mikeno means "poor" and is so named for its harsh slopes which preclude human habitation.
The following lists events that happened during 2002 in the Democratic Republic of the Congo.
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.
