The island is a basalt pillar with sheer sides, the only visible portion of a submarine volcanic caldera extending 2.6 kilometres (1.6 mi) south-east at an average depth of 240 metres (790 ft). The above sea-level portion measures approximately 84 metres east-west and 56 metres north-south, with a summit height of 99 metres (325 ft).
The event involved the movement of 100 million cubic meters of volcanic material. A region of 3.9 to 5.0 sq mi (10 to 13 km 2) of the summit was altered and populated by bus-sized pillow lava blocks, precariously perched along the outer rim of the newly formed crater. "Pele's Vents", an area on the southern side, previously considered stable ...
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 island was formed as a volcano 1.5 to 2.5 million years ago, the result of the Society hotspot in the mantle under the oceanic plate that formed the whole of the Society Archipelago. [1] It is theorized that the current bays were formerly river basins that filled during the Holocene searise. Moʻorea is about 16 km (10 miles) across.
Monowai Seamount is a large volcano which consists of an 8 kilometres (5.0 mi) wide conical stratovolcano that rises 1.2 kilometres (0.75 mi) [16] from the Tonga-Kermadec Ridge in a part of the ocean with a depth of 1,000–1,500 metres (3,300–4,900 ft) [4] to a depth of less than 100 metres (330 ft) below sea level; [16] the exact depth of ...
The 2018 lower Puna eruption was a volcanic event on the island of Hawaiʻi, on Kīlauea volcano's East Rift Zone that began on May 3, 2018. It is related to the larger eruption of Kīlauea that began on January 3, 1983, though some volcanologists and USGS scientists have discussed whether to classify it as a new eruption. [2]
A central feature of Jeju is Hallasan, the tallest mountain in South Korea and a dormant volcano, which rises 1,950 meters above sea level. The main volcano includes 360 satellite volcanoes. Volcanic activity on Jeju began approximately in the Cretaceous and lasted until the early Tertiary period. The most recent eruptions are estimated to be ...
