Ranakah volcano news & activity updates

Ranakah volcano (Flores, Indonesia) - increased seismicity triggers alert

Saturday Sep 03, 2011 07:29 AM |

The Indonesian Volcanological Survey (PVMBG) has raised the alert status for Anak Ranakah volcano in the district of Manggarai on the island of Flores in southeastern Indonesia to 2 out of 4 (meaning eruption warning) on 26 August.
Seismic activity and volcanic have increased recently and the lava dome of Anak Ranakah is emitting a small plume of white steam.
Very little is known about Ranakah volcano. There is only one previous eruption, which constructed Anak Ranakah lava dome in December 1987 - January 1988 during the first historic eruption of 2247 m high Ranakah volcano. The lava dome produced powerful explosions with ash plumes up to 8 km height and pyroclastic flows.
There is concern that collapse of parts of the instable lava dome could trigger pyroclastic flows. Local people have been advised to stay far from the summit and climbers are currently not allowed to approach it. Volcanologists are monitoring the situation and local authorities "will review the situation to decide if extra precautions should be taken any time soon".
