Alaska Has 6.1 Quake Followed By 2 Aftershocks (3.6, 4.0)

No tsunami threat to Hawaii from Alaska earthquake

The Pacific Tsunami Warning Center said a magnitude 6.1 earthquake that struck Alaska today poses no local threat of a tsunami.
The quake struck at 3:35 p.m. Hawaii time at a depth of about 16 miles and about 632 miles southwest of Anchorage.

Two aftershocks from Alaska’s Nov. 30 earthquake jolted Southcentral residents Sunday evening. A 3.6 magnitude aftershock at 5:28 p.m. was followed by a 4.0 shake just an hour later.
According to the Alaska Earthquake Center, the first of the two aftershocks was centered 15 miles north of Joint Base Elmendorf-Richardson and occurred at a depth of 18.5 miles. The 4.0 quake struck 11 miles northwest of Anchorage at 6:28 p.m. at a depth of 12.3 miles. 
“This has been an eventful hour,” wrote officials with the Alaska Earthquake Center on their Twitter feed. In addition to the two aftershocks felt in Southcentral, the agency reported a 6.1 quake at 5:35 p.m. - 650 miles to the Southwest. The quake was 61 miles southeast of King Cove and felt from King Cove to Unalaska.
