M4.1 Earthquake near Kepulauan Babar, Indonesia — June 10, 2026
2026-06-10 20:22:44 UTC (2026-06-10) · approx. 5:22 AM UTC+9 local
On June 10, 2026 at 20:22 UTC, a magnitude 4.1 intermediate depth earthquake struck near Kepulauan Babar, Indonesia, at a depth of 159.0 km and coordinates -7.1019°, 129.3253°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 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 5.9 mainshock that occurred 17 days ago 253 km ENE of Lospalos, Timor Leste. 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 4.1 earthquake near Kepulauan Babar, Indonesia?
The magnitude 4.1 earthquake that struck near Kepulauan Babar, Indonesia on June 10, 2026 at 20:22 UTC had a depth of 159.0 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 4.1 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.9 one earlier?
No. This magnitude 4.1 earthquake is an aftershock of the larger magnitude 5.9 mainshock that occurred earlier 253 km ENE of Lospalos, Timor Leste. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
