On June 10, 2026 at 01:04 UTC, a magnitude 4.3 shallow crustal earthquake struck 105 km WNW of Mantua, Cuba, at a depth of 16.0 km and coordinates 22.7558°, -85.1805°.

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 6.1 mainshock that occurred 1 day ago 102 km WNW of Mantua, Cuba. Since the mainshock, the USGS has recorded 1 aftershocks in this area. Aftershock activity is expected to continue for weeks to months as stresses on surrounding faults redistribute.

Common Questions

How strong was the magnitude 4.3 earthquake near Mantua, Cuba?

The magnitude 4.3 earthquake that struck 105 km WNW of Mantua, Cuba on June 10, 2026 at 01:04 UTC had a depth of 16.0 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 M6.1 one earlier?

No. This magnitude 4.3 earthquake is an aftershock of the larger magnitude 6.1 mainshock that occurred earlier 102 km WNW of Mantua, Cuba. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

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.
