The magnitude 6.1 earthquake late in the evening on Sunday May 30 occurred about 100 km, or 60 miles, east of Talkeetna and was felt across much of mainland Alaska. In our shakemap for this event (Figure 1) the region that experienced shaking corresponds roughly to the areas marked in light blue, including everything from the Kenai, to Fairbanks, to Cordova and east. Most people who experienced this earthquake were a considerable distance away. As a result, the shaking was mostly experienced as long rolling motions and not the sharp jolt experienced by people close to the epicenter. The triangles in Figure 1 show the locations of instruments we used to measure the shaking. The closest stations registered shaking equivalent to about 5% of the acceleration of gravity (or ‘’5% g”) Though generally not enough to cause significant damage in Alaska, it certainly woke up a lot of folks who had turned in for the evening. Though aftershocks are occurring and should continue, the location makes it unlikely that many of these will be felt, except by folks living quite close to the epicenter.
