Quake swarms at neighboring Alaska volcanoes raise concerns

Associated Press  

ANCHORAGE, Alaska — Not one but two volcanoes on the same island in Alaska’s Aleutian chain were rocked by earthquakes on Friday, prompting concerns about a possible eruption. “If an eruption were to occur, it is uncertain at this stage if it would come from Takawangha or Tanaga,” officials at the Alaska Volcano Observatory said in a statement that raised the alert level for the two volcanoes. “We’re still getting earthquakes up above magnitude 3 going on quite regularly,” said John Power, a research geophysicist with the U.S. Geological Survey stationed at the Alaska Volcano Observatory in Anchorage. Seismic activity ramped up earlier this week at Tanaga Volcano, the middle of three volcanoes on Tanaga Island, located about 1,250 miles southwest of Anchorage, the state’s major population area. “We’ve seen actually earthquake activity building beneath both epicenters and in between them, which is causing us quite a bit of concern about what’s going on,” Power said.

Sumatra earthquake triggered quakes 8,000 km away

Large earthquakes have been found to increase the chances of subsequent quakes across the globe. Apart from causing earthquake and tsunami, the seismic waves from the 2004 Sumatra-Andaman quake, which had a magnitude of 9.1, led to weakening, and hence increasing the chances of failure of other faults far away. Similarly, a cluster of four earthquakes of magnitude more than …
