'Swarm' of earthquakes hit Alaska's western Aleutian Islands without damage
A series of moderate to strong earthquakes that struck Alaska's western Aleutian Islands and offshore areas Sunday comprised what scientists call a swarm," but the state's earthquake monitors said the seismic events should not cause residents to worry. There were no immediate reports of damage or injuries in the area around Adak, Amchitka and Kiska islands some 2,200 km west of Anchorage. Of the three remote islands, only Adak Island, with a population of about 300 people, is inhabited. Nine quakes measuring at least magnitude 5.0 struck on or near the islands and in a cluster offshore to the south Sunday morning and afternoon, according to the Alaska Earthquake Centre. Three of the quakes measured 6.0 or stronger, with the biggest a 6.3 temblor offshore. In a summary posted on its website Sunday night, the earthquake center said the 6.3 magnitude quake at a depth of about 18 km did not raise concern on its own because of its offshore location and the lack of damage reports, while

6.9 earthquake strikes off Alaska, no tsunami warning issued
A 6.9 earthquake struck off the coast of the Alaskan Peninsula early Saturday morning, the US Geological Survey reported. Despite the size of the quake, no tsunami warnings were issued. The closest place to the epicenter was Perryville, home to a little more than 100 people 85 miles (135 kilometers) northwest. Much of the land around the part of the Gulf of Alaska where the earthquake struck just before 4 a.m. is home to wildlife refuges. Alaska is a hotbed of seismic activity. The Alaska Earthquake Center, housed at the University of Alaska, Fairbanks, detects an earthquake every 15 minutes, on average, according to its website. The center also says that 75 per cent of all US earthquakes with a magnitude over 5 occur in Alaska.
