Iotourishima is located 65 km west of Tokunoshima Island. On exceptionally clear days, Iōtorishima can be seen from the west coast of Tokunoshima. The 2.50 km 2 [2] large island consists of two interconnected volcanoes made from andesite. The southern Gusuku kazan (グスク火山, "Castle Volcano") is a lava dome located in the center of the ...
New island forming in the Zubair Group, about 0.5 km (0.3 mi) NNW of Rugged Island. NASA satellite image, January 7, 2012. Zubair Group, Al Zubair Group or Zubayr Group (Arabic: مجموعة جزر الزبير, or simply: جزر الزبير) is a group of 10 major volcanic islands, on top of an underlying shield volcano in the Red Sea, which reach a height of 191 m (627 ft) above sea level.
Nishinoshima (Japanese: 西之島, "western island") is a volcanic island located around 940 km (584 mi) south-southeast of Tokyo that is part of the Volcano Islands arc. . Nishinoshima is located about 130 km to the west of the nearest inhabited Ogasawara islands, Chichijima Island, hence the name; the other Ogasawara island groups are aligned more to the north–
The most recent eruption, in 1952, formed a small lava dome on the island's coast. Krenitsyn Peak has a summit crater 350 m wide and is the highest point of the volcano and on the entire Onekotan Island. Another caldera, Nemo Peak, lies at the northern end of the island, and it also contains a central cone and crater lake.
Rakata is a volcanic cone with its northern face being a vertical cliff, exposing much of its eruptive history.More than 25 extrusion dikes have been counted; the largest at the center runs from sea level to 320 meters above and terminates in a large (about 6 meters in diameter), convex form.
Two volcanoes erupted during the summer of 2008 on the eastern Aleutian Islands. On July 12, 2008, Mount Okmok erupted, and it continued to erupt for a month. A giant, rapidly moving ash and gas cloud shot up to a height of 15,240 m as a result of this eruption. [2] Mount Kasatochi was home to the other eruption, which occurred on August 7 and 8.
The island consists of two stratovolcanos connected by a relatively flat isthmus. Krenitsyn-(Russian: Креницын; Japanese 黒石山; Kuroishiyama) with a height of 1,324 meters (4,344 ft) is the prominent caldera at the southern end of the island. This volcano was named after Captain Pyotr Krenitsyn of the Imperial Russian Navy. [2]
Previously, up to 5,000 people living near the volcano have had to be evacuated for their safety. The volcano's recent history includes eruptions in 1966, 2005 and 2016. [ 27 ] In general, the new activity can happen anywhere on Ambae, but with highest likelihood in the rift zone, a long 2 km (1.2 mi) wide region that runs the length of the ...
