Global Volcanic Activity/ Unrest New/ Ongoing – 092601

Mt Agung volcano has reached a critical stage with about 500 tremors recorded in 24 hrs –BNPB

“…all measuring instruments show there is growing pressure towards the surface,” spokesperson for the National Disaster Mitigation Agency (BNPB) told the local media.

“The chance that an eruption will happen is quite high. But it cannot be predicted when it will happen.”

About 60,000 people have fled the restive volcano in Bali as rising magma and enhanced seismicity threaten an imminent eruption, officials said.

Some 2,000 cattle have also been evacuated from the villages surrounding the volcano.

Kizimen Volcano blew out a plume of ash, smoke and steam over the  Gulf of Kamchatka on February 1, 2011.  Kizimen recent eruptions are said to be both explosive and effusive. This natural-color image was taken by the MODIS aboard the Aqua satellite. Source: NASA-EO. Click images to enlarge.

Kizimen Volcano on Russia’s Kamchatka Peninsula (elev. 8,153 ft/2,485 m: KVERT 13 june 2011),  ejected a plume of ash, steam and volcanic gasses on January 6, 2011, when ALI on NASA’s EO-1 satellite captured this natural-color image.  Kizimen had released continuous ash emissions since December 31, 2010, KVERT reported. Kizimen erupted explosively 83 years ago. Source: NASA-EO.

VOW: Golden Trout Creek

A cluster of 66 shocks have rocked a a 15 square km area centered about 36.392°N, 117.861°W, some 41 km east of the Golden Trout Creek volcano field in central California, in the past few days. Although most of the quakes were tremors measuring less than M 3.0, the largest shock measured 5.2.

Volcano Details:

Country:  United States
Region:  California (USA)
Volcano Type: Volcanic field
Volcano Status: Tephrochronology
Last Known Eruption: 5550 BC ± 1000 years
Summit Elevation: 2,886 m  (9,468 feet)
Latitude: 36.358°N   (36°21’30″N)

The Golden Trout Creek volcanic field consists of a group of Quaternary alkali olivine basaltic cinder cones and lava flows in the Toowa valley of the Sierra Nevada about 25 km south of Mount Whitney. Lava flows from the Golden Trout Creek volcanic field erupted through Mesozoic granitic rocks of the Sierra Nevada batholith during several episodes dating back to about 743,000 years ago, when the Little Whitney cinder cone and lava flows were erupted. The South Fork cone was erupted about 176,000 years ago and produced the largest lava flow of the volcanic field, which traveled 10 km to the west, possibly as far as the floor of Kern Canyon. Tunnel cone to the north of South Fork (Red Hill) cone is undated, but its lava flow is overlain by glacial deposits and it is thought to be only slightly younger than South Fork cone. The youngest lava flow, from Groundhog cone, is unglaciated and thought to be about 5-10,000 years old (Moore and Lanphere 1983). The lava flow from Groundhog cone traveled 6 km west down Golden Trout Creek on top of the older flow from South Fork cone.—GVP.   Photo: Rick Howard, 2002 (courtesy of Del Hubbs, U S Forest Service).
