On May 10, 2025 at 17:52 UTC, a magnitude 4.2 intermediate depth earthquake struck 53 km WNW of Kirakira, Solomon Islands, at a depth of 88.0 km and coordinates -10.2699°, 161.4662°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 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 5.1 mainshock that occurred 10 days ago 14 km NW 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 4.2 earthquake near Kirakira, Solomon Islands?

The magnitude 4.2 earthquake that struck 53 km WNW of Kirakira, Solomon Islands on May 10, 2025 at 17:52 UTC had a depth of 88.0 km. For context, this was a light earthquake commonly felt near the epicenter.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.2 earthquakes can continue for several days and gradually diminish over time.

Is this the same earthquake as the M5.1 one earlier?

No. This magnitude 4.2 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 14 km NW of Kirakira, Solomon Islands. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

Understanding This Data

Magnitude 4.2 earthquakes are often felt but rarely cause damage.
