A strong, rolling earthquake rocked Anchorage and a wide area of southern and interior Alaska, sending people scurrying into the streets. There were no immediate reports of serious damage or injuries. The quake was measured at a preliminary magnitude of 6.4 and was centered 125 miles southwest of Anchorage. It was felt in Anchorage, Kodiak, Fairbanks, Palmer and Cordova, shaking an area about 225 miles by 500 miles.

A strong earthquake rattled the Aleutian Islands on Thursday evening, but no damage or injuries were reported, the Alaska Tsunami Warning Center said. The 6.7-magnitude quake was centered 210 miles southwest of the town of Adak.

Miriam Hilscher was knocked to the floor by a violent, unseen force and couldn't get up. She had no way of knowing whether her daughter and husband, in other parts of the house, were safe. Not until the rolling and shaking stopped 4 1/2 minutes later. The Hilschers all survived the gigantic, 8.5-magnitude earthquake that ripped through Alaska in 1964. One hundred and thirty-one others didn't.

Redoubt Volcano blew its top again shortly after a moderate earthquake rocked a wide area of Alaska and geologists said the two events might be related. Redoubt's latest eruption sent an ash plume 35,000 feet high blowing toward the sparsely populated mountainous region to the northwest, the Alaska Volcano Observatory said. Geologists said the eruption from the 10,197-foot mountain 110 miles southwest of Anchorage appeared to shoot less ash into the sky than in previous eruptions.

A major earthquake jolted south-central Alaska today, knocking out power to one community and prompting authorities to urge the evacuation of low-lying coastal areas because of a possible sea wave. The quake struck at 11:23 a.m. PST and measured 7.4 on the Richter scale. It was centered 300 miles southeast of Anchorage in the Gulf of Alaska. The Tsunami Warning Center in Palmer issued a warning covering nearly the entire southern coastline of the state and coastal British Columbia.

Three earthquakes and three aftershocks rocked the Aleutian Islands near Alaska on Wednesday, hammering a Navy air station on the island of Adak and sending a tidal wave across the Pacific that chased people to high ground in Hawaii and Northern California. No injuries were reported. The quake, which caused a tsunami, popularly known as a tidal wave, damaged buildings at Adak Naval Air Station. Walls cracked, and windows shattered.

It began as series of small shuddering earthquakes beneath Alaska's Mt. Redoubt that gradually coalesced into a high-frequency "scream," according to seismologists. While scientists could only guess as to what triggered the vibrations, there was no question about what happened next: The seismic scream was followed by 30 seconds of silence, and then a series of volcanic eruptions -- 20 over a two-week period -- that launched an enormous plume of ash resembling a mushroom cloud. In a study published recently in Nature Geoscience, researchers examined data from the 2009 eruption and concluded that the sustained vibrations were caused by numerous so-called stick-slip movements on faults more than a mile beneath the volcano.
