Lopevi

Stratovolkan · Vanuatu · 1413 m

Lopevi is seen here in an aerial view from the NW, with lava flows that erupted from NW-SE-trending fissures forming the barren slopes in the foreground. The small 7-km-wide island is known locally as Vanei Vollohulu. Historical eruptions date back to the mid-19th century. The island was evacuated following major eruptions in 1939 and 1960.

Ringkasan geologi

The small 7-km-wide conical island of Lopevi, known locally as Vanei Vollohulu, is one of Vanuatu's most active volcanoes. A small summit crater containing a cinder cone is breached to the NW and tops an older cone that is rimmed by the remnant of a larger crater. The basaltic-to-andesitic volcano has been active during historical time at both summit and flank vents, primarily along a NW-SE-trending fissure that cuts across the island, producing moderate explosive eruptions and lava flows that reached the coast. Historical eruptions at the 1413-m-high volcano date back to the mid-19th century. The island was evacuated following major eruptions in 1939 and 1960. The latter eruption, from a NW-flank fissure vent, produced a pyroclastic flow that swept to the sea and a lava flow that formed a new peninsula on the western coast.
