On June 2, 2026 at 14:31 UTC, a magnitude 4.3 shallow crustal earthquake struck 180 km N of Fais, Micronesia, at a depth of 10.0 km and coordinates 11.3835°, 140.7571°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 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 25 days ago 187 km N of Fais, Micronesia. 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 4.3 earthquake near Fais, Micronesia?

The magnitude 4.3 earthquake that struck 180 km N of Fais, Micronesia on June 2, 2026 at 14:31 UTC had a depth of 10.0 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 4.3 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 4.3 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 187 km N of Fais, Micronesia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

Understanding This Data

Magnitude 4.3 earthquakes are often felt but rarely cause damage.
