A moderately shallow magnitude 3.6 earthquake was reported in the afternoon near Homer, Kenai Peninsula, Alaska, USA.
According to the United States Geological Survey, the quake hit on Tuesday 4 May 2021 at 4:23 pm local time at a moderately shallow depth of 22 miles. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.6 as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Munina (pop. 880) located 3 miles from the epicenter, Anchor Point (pop. 1,900) 17 miles away, Fritz Creek (pop. 1,900) 23 miles away, Diamond Ridge (pop. 1,200) 23 miles away, Homer (pop. 5,500) 25 miles away, Cohoe (pop. 1,400) 28 miles away, and Kalifornsky (pop. 7,900) 31 miles away. In Kenai (pop. 7,700, 41 miles away), the quake was probably not felt.
