M3.0 Earthquake 11 km ENE of Pāhala, Hawaii — September 13, 2025
2025-09-13 20:53:45 UTC (2025-09-13) · approx. 10:53 AM UTC-10 local
On September 13, 2025 at 20:53 UTC, a magnitude 3.0 shallow crustal earthquake struck 11 km ENE of Pāhala, Hawaii, at a depth of 4.8 km and coordinates 19.2488°, -155.3792°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 567 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 77 m — 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 6.0 mainshock that occurred 5 days ago 13 km S of Honaunau-Napoopoo, Hawaii. Since the mainshock, the USGS has recorded 17 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 3.0 earthquake near Pāhala, Hawaii?
The magnitude 3.0 earthquake that struck 11 km ENE of Pāhala, Hawaii on September 13, 2025 at 20:53 UTC had a depth of 4.8 km. For context, this was a minor earthquake typically detected only by instruments.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.0 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M6.0 one earlier?
No. This magnitude 3.0 earthquake is an aftershock of the larger magnitude 6.0 mainshock that occurred earlier 13 km S of Honaunau-Napoopoo, Hawaii. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
