M5.1 Earthquake 102 km ESE of Kirakira, Solomon Islands — June 27, 2026
2026-06-27 00:03:23 UTC (2026-06-27) · approx. 11:03 AM UTC+11 local
Aftershock of the M5.2 mainshock.
On June 27, 2026 at 00:03 UTC, a magnitude 5.1 shallow crustal earthquake struck 102 km ESE of Kirakira, Solomon Islands, at a depth of 10.0 km and coordinates -10.6505°, 162.8402°. This earthquake was detected by 38 seismic stations with good location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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 5.2 mainshock that occurred 19 days ago 135 km E of Kirakira, Solomon Islands. Since the mainshock, the USGS has recorded 0 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 5.1 earthquake near Kirakira, Solomon Islands?
The magnitude 5.1 earthquake that struck 102 km ESE of Kirakira, Solomon Islands on June 27, 2026 at 00:03 UTC had a depth of 10.0 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at -10.6505°, 162.8402°, which is 102 km ESE of Kirakira, Solomon Islands.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.1 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.2 one earlier?
No. This magnitude 5.1 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 135 km E of Kirakira, Solomon Islands. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
