M2.9 Earthquake 4 km W of Kahaluu-Keauhou, Hawaii — June 13, 2026
2026-06-13 07:48:18 UTC (1 day ago) · approx. 9:48 PM UTC-10 local
Felt by 85 people across nearby locations. Aftershock of the M6.0 mainshock.
On June 13, 2026 at 07:48 UTC, a magnitude 2.9 shallow crustal earthquake struck 4 km W of Kahaluu-Keauhou, Hawaii, at a depth of 4.6 km and coordinates 19.5687°, -156.0058°. This earthquake was detected by 42 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 157, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 374 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 63 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 22 days ago 13 km S of Honaunau-Napoopoo, Hawaii. Since the mainshock, the USGS has recorded 21 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
The epicenter is located in Hawaii, a region characterized by intraplate volcanic activity over the Hawaiian mantle plume hotspot, with seismicity driven by magma intrusion and flank instability. View all earthquakes in Hawaii.

Common Questions
How strong was the magnitude 2.9 earthquake near Kahaluu-Keauhou, Hawaii?
The magnitude 2.9 earthquake that struck 4 km W of Kahaluu-Keauhou, Hawaii on June 13, 2026 at 07:48 UTC had a depth of 4.6 km. For context, this was a minor earthquake typically detected only by instruments.
Where did the earthquake occur?
The earthquake epicenter was located at 19.5687°, -156.0058°, which is 4 km W of Kahaluu-Keauhou, Hawaii. View all earthquakes in Hawaii.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 2.9 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 2.9 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.
Has Hawaii had earthquakes this big before?
The largest recorded earthquake in Hawaii was the M7.9 Ka'u District earthquake of April 2, 1868. Today's magnitude 2.9 event is significantly smaller than that historical record.
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.
