The resulting deposits formed a fan-like pattern of overlapping sheets, tongues, and lobes. At least 17 separate pyroclastic flows occurred during the May 18 eruption, and their aggregate volume was about 0.05 cu mi (0.21 km 3). [9] The flow deposits were still at about 570 to 790 °F (300 to 420 °C) two weeks after they erupted. [9]
The two main types of lava field structures are defined as sheet flow lava and pillow lava. Sheet flow lava appears like a wrinkled or folded sheet, while pillow lava is bulbous, and often looks like a pile of pillows atop one another. [2] An important aspect of lava flow morphology is a phenomenon known as lava flow inflation. This occurs in ...

Its 1995 eruptions resulted in the abandonment of its capital city, Plymouth. Soufrière on the island Saint Vincent; Mount Pelée on the island Martinique. Its devastating eruption on 8 May 1902 resulted in the complete destruction of its capital city, Saint-Pierre, with the deaths of more than 30,000 inhabitants within it.
Karymsky is a symmetrical stratovolcano rising within a 5-km-wide caldera that formed during the early Holocene. Much of the cone is mantled by lava flows less than 200 years old. Historical eruptions have been vulcanian or vulcanian-strombolian with moderate explosive activity and occasional lava flows from the summit crater. [2]
The previous eruption in the area started on Jan. 14 and lasted roughly two days, with lava flows reaching the outskirts of the Grindavik fishing town, whose nearly 4,000 inhabitants had been ...
The Greenstone Flow is one of the world's largest known lava flows, estimated at a volume ~1650 to ~6000 cubic kilometers of mafic lava. [2] [3] In places, the lava pooled to depth of 487 meters. [4] The flow was generated by a flood basalt eruption during the Midcontinental Rift, which occurred 1.1 billion years ago. [5]
The lava is flowin'. Molten rock likely from miles underground is flowing out of a newly opened fissure in the ground on Iceland's Reykjanes Peninsula. It's the latest activity in an already ...
