Volcano activity world-wide summary 7-13 Nov 2012
The latest Smithsonian / USGS Weekly Volcanic Activity Report is one of the more interesting ones in a while, summarized as follows:
Thu, 15 Nov 2012, 06:5806:58 AM | BY: T
-- new activity ---
Cleveland (Aleutians): small explosion on 10 Nov, detected by ash plume.
Kizimen (Kamchatka): lava flows effusing from summit and E flank, summit incandescence, strong gas-and-steam activity, and hot avalanches on the S flank. Thermal anomaly detected in satellite images.
Paluweh (Flores, Indonesia): ash emissions during 11-13 Nov reaching 8,000 ft (2.4 km) altitude.
Reventador (Ecuador): new phase of activity started on 9 November, characterized by lava flows from the crater, growing lava dome with rock falls now highest point of volcano, increase in seismicity, thermal anomalies detected in satellite images.
Villarica (Chile): signs of reawakening, steaming (no incandescence observed since mid April).
--- ongoing activity ---
Fuego (Guatemala): small strombolian explosions with ash clouds 250-400 m height, lava flow 200-500 m long down the Ceniza drainage.
Karymski (Kamchatka): moderate seismic activity, thermal anomaly, explosion on 10 Nov with ash plume to 5.5 km (18,000 ft) altitude.
Kilauea (Hawaii): Lava lake in Kilauea's Halema'uma'u and elevated spattering / lava lake / small lava flow activity in Pu'u 'O'o Crater. Lava flows active in the Royal Gardens subdivision and across the coastal plain, but about 500 m from the coast.
Lokon (North Sulawesi, Indonesia): small eruption on 11 Nov.
Ruapehu (New Zealand): summary of activity Jan-Oct, crater lake cooler than in Jan, no unusual signs of activity.
Sakurajima (Japan): explosions mainly from Showa Crater with ash plumes up to 4 km altitude and ejecta landing in up to 1.3 km distance. Very small eruptions at Minami-dake Crater during 8-9 Nov.
Shiveluch (Kamchatka): viscous lava flow from lava dome, hot avalanches, ash emission on 12 Nov.
Tongariro (New Zealand): field report from 5 Nov and gas measurements - elevated degassing, low seismic activity.
