M5.0 Earthquake east of the Kuril Islands — October 13, 2022
2022-10-13 06:20:41 UTC (2022-10-13) · approx. 4:20 PM UTC+10 local
Aftershock of the M5.5 mainshock.
On October 13, 2022 at 06:20 UTC, a magnitude 5.0 shallow crustal earthquake struck east of the Kuril Islands, at a depth of 10.5 km and coordinates 44.8016°, 150.2295°. This earthquake was detected by 128 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.5 mainshock that occurred 2 days ago 168 km ESE of Kuril’sk, Russia. Since the mainshock, the USGS has recorded 1 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 5.0 earthquake east of the Kuril Islands?
The magnitude 5.0 earthquake that struck east of the Kuril Islands on October 13, 2022 at 06:20 UTC had a depth of 10.5 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at 44.8016°, 150.2295°, which is east of the Kuril Islands.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.0 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.5 one earlier?
No. This magnitude 5.0 earthquake is an aftershock of the larger magnitude 5.5 mainshock that occurred earlier 168 km ESE of Kuril’sk, Russia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
