M5.2 Earthquake 187 km SE of Akutan, Alaska — May 5, 2024
2024-05-05 08:27:46 UTC (2024-05-05) · approx. 9:27 PM UTC-11 local
Felt by 3 people across nearby locations.
On May 5, 2024 at 08:27 UTC, a magnitude 5.2 shallow crustal earthquake struck 187 km SE of Akutan, Alaska, at a depth of 10.0 km and coordinates 52.9219°, -163.8153°. The earthquake was reported felt by 3 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 2.6 (weak). This earthquake was detected by 153 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 417, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Alaska, a region characterized by Pacific Plate subduction beneath the North American Plate, producing frequent megathrust and crustal earthquakes along the Aleutian arc. The nearest mapped fault system is the Aleutian megathrust. View all earthquakes in Alaska.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.2 earthquakes can continue for days to weeks and gradually diminish over time.
Has Alaska had earthquakes this big before?
The largest recorded earthquake in Alaska was the M9.2 Great Alaska earthquake of March 27, 1964. Today's magnitude 5.2 event is significantly smaller than that historical record.
