Other notable events include two felt earthquakes on October 10: a magnitude 4.2 earthquake located 52 miles N of the capital city Juneau that was felt in the SE Alaska and a magnitude 4.4 earthquake in the Cook Inlet region that was felt in Kenai Peninsula communities. These two events occurred within several hours of each other.
