M4.6 Earthquake 66 km SSE of Kirakira, Solomon Islands — November 25, 2020
2020-11-25 16:27:07 UTC (2020-11-25) · approx. 3:27 AM UTC+11 local
Aftershock of the M5.6 mainshock.
On November 25, 2020 at 16:27 UTC, a magnitude 4.6 shallow crustal earthquake struck 66 km SSE of Kirakira, Solomon Islands, at a depth of 10.0 km and coordinates -11.0133°, 162.1410°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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 5.6 mainshock that occurred 29 days ago 98 km SE 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 4.6 earthquake near Kirakira, Solomon Islands?
The magnitude 4.6 earthquake that struck 66 km SSE of Kirakira, Solomon Islands on November 25, 2020 at 16:27 UTC had a depth of 10.0 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at -11.0133°, 162.1410°, which is 66 km SSE of Kirakira, Solomon Islands.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.6 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.6 one earlier?
No. This magnitude 4.6 earthquake is an aftershock of the larger magnitude 5.6 mainshock that occurred earlier 98 km SE of Kirakira, Solomon Islands. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
