Light mag. 3.4 earthquake - Gulf of Alaska, 129 mi west of Juneau, Alaska, USA, on Saturday, May 1, 2021 5:53 am (GMT -8)

Light magnitude 3.4 earthquake at 11 km depth

1 May 13:57 UTC: First to report: USGS after 4 minutes.
1 May 18:24: Magnitude recalculated from 3.6 to 3.4. Hypocenter depth recalculated from 14.5 to 10.5 km (from 9 to 6.5 mi). Epicenter location corrected by 10.8 km (6.7 mi) towards W.
Update Sat, 1 May 2021, 14:03
Small tremor of magnitude 3.6 just reported 52 miles west of Elfin Cove, Alaska, United States
3.6 quake 1 May 5:53 am (GMT -8)
3.6 quake 1 May 5:53 am (GMT -8)
An earthquake of magnitude 3.6 occurred early morning on Saturday 1 May 2021 at 5:53 am local time near Elfin Cove, Hoonah-Angoon, Alaska, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a shallow depth of 9 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Elfin Cove (pop. 20, 52 miles away), the quake was probably not felt.

If you did NOT feel the quake although you were in the area, please report it! Your contribution is valuable to earthquake science, seismic hazard analysis and mitigation efforts. You can use your device location or the map to indicate where you were during the earthquake. Thank you!

Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
