1,800 aftershocks since Alaska quake
Dozens of small earthquakes rattled Anchorage and Mat-Su on Sunday night and early Monday — and a few bigger ones probably caused unwanted wake-ups.
Twin magnitude 3.5 shakers struck at 9:51 and 9:52 p.m. Sunday, the first 10 miles north of Anchorage and the second 18 miles northwest of Joint Base Elmendorf-Richardson, according to the U.S. Geological Survey Earthquake Science Center.
A magnitude 3.4 quake was measured 10 miles northwest of Anchorage at 10:40 p.m. A 3.5 hit at 1:30 a.m., 17 miles northwest of JBER, followed by a magnitude 3.8 just before 3:20 a.m. 13 miles northwest of JBER. Twin 3.2 quakes followed just before 6 a.m., one near Anchorage and the other near Wasilla.
