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)
Source: Global Volcanism Program (GVP)


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.

SI /USGS Weekly Volcanic Activity Report
(23 September – 29 September 2009)

New activity/Unrest:

News From GVP:

CVGHM reported that on 26 September a “thunderous” noise from Dieng was heard from 2 km away. The next day, a phreatic eruption from an unspecified crater ejected mud as far away as 140 m S.

KVERT reported that on 17 and 22 September a weak thermal anomaly over Karymsky was detected in satellite imagery. Scientists flying near Karymsky in a helicopter on 22 September saw ash plumes that rose to an altitude of 1.7 km (5,600 ft) a.s.l. and drifted E. —GVP

Earthquakes: Human Enhanced Disasters – UPDATE 2 Oct 2009

Posted by feww on October 2, 2009

Sumatra Double Earthquakes

FEWW Moderators believe it’s highly probable that another 2 or more strong to powerful quakes could strike the region in the coming days. Padang and other coastal towns in Sumatra and Java must also prepare for a possible tsunami.

At least 1,200 bodies have been recovered following widespread damage after a magnitude 7.9 quake  struck southern Sumatra, Indonesia, on Wednesday, according to the officials.

The Death Toll Could Reach Many Thousands


There are no reports of deaths from the 6.8 magnitude quake that struck southern Sumatra  on Thursday. However. a local radio station reported that a dozen 12 people had been injured and up to 75 building damaged in  the town of Jambi.

“People are trapped and screaming for help but they are below huge slabs which will take heavy equipment to move,” an aid worker said.

“I saw dozens of the biggest buildings collapsed in town. Most of the damage is concentrated in the commercial center market, which was fully packed,” he said.

Images that will be repeated throughout the world, again, and again

Regional Economy

West Sumatra, a major producer of crude palm oil, is also affected economically.

Indonesia’s finance minister Sri Mulyani said: “This region has been damaged seriously, including its infrastructure,” adding that her government has allocated $25 million over two month for emergency operations.
