Alaska News,
30 November, 2012



Residents on Kodiak Island and the Kenai Peninsula were shaken awake at 11:00pm on Friday night as a 5.9 magnitude earthquake struck the Alaska Peninsula/ South Central region.

The quick jolt occurred 69 miles north of Larsen Bay and 238 miles southwest of Anchorage. It was generated at a depth of 52.1 miles beneath the surface on the mainland across from Kodiak Island.

The location of this earthquake was equidistant between the long quiet region of Devil's Desk and Kaguyak Volcano.

Devil's Desk is a volcanic neck of a former stratovolcano now completely surrounded by Hook Glacier. Erosion has removed most of the stratovolcano. Wes Hildreth of USGS as well as others state that Devil's Desk was active 292,000 years ago to the Holocene.

Kaguyak Volcano is another stratovolcano that had its last major eruption about 5,800 years before present, and has been largely quiet since that time with no recent eruptions or activity for at least the last 1,200 years.

The National Oceanic and Atmospheric Administration's West Coast and Alaska Tsunami Warning Center issued a statement advising that there was no tsunami danger from this quake.

A quake measuring 4.1 on the Richter scale broke out Friday on the Vietnam-Laos border, in an area near Nghe An and Ha Tinh provinces in Central Vietnam.
The quake, which was located at 18.65 degrees north latitude and 104.81 degrees west longitude, occurred at 4:40:20 p.m. Hanoi time, said the Earthquake Information and Tsunami Warning Center under the Global Physic Institute.
The quake, with its epicenter being 10 km underground in the Lao territory, came from the Rao Nay fault that runs from northwest to southeast from Laos to Ha Tinh, the center said.  
The intensity of quakes coming from the fault can reach 6 degrees, experts warned. Last month a quake measuring 4.7 on the Richter scale hit Bac Tra My District of Quang Nam Province, also in Central Vietnam.
The quake, which broke out on November 15 near the Song Tranh 2 Hydropower Plant, has been the strongestin the province in the past 55 years.
