According to the scary red font at CBS 5, "A strong earthquake has just jolted urban centers of Alaska." Earthquake.usgs.gov, lists "5.7 Southern Alaska, 36 minutes ago." Which sounds like it was a big one too. Well, sort of. More info as it comes in. Update: The epicenter, reports Seattle PI, "was 58 miles from the state's largest city, Anchorage, where the rumbled continued for several moments." Also, "the West Coast and Alaska Tsunami Warning Center reported the magnitude at a slightly weaker 5.3 and said no tsunami will be generated." This, of course, is bittersweet news on a relatively tepid news day.
