On October 27, 2022 at 18:02 UTC, a magnitude 4.1 intermediate depth earthquake struck near Banda Sea, at a depth of 152.0 km and coordinates -6.4687°, 130.1201°.

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 5.7 mainshock that occurred 18 days ago 271 km WSW of Tual, Indonesia. 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 Banda Sea?

The magnitude 4.1 earthquake that struck near Banda Sea on October 27, 2022 at 18:02 UTC had a depth of 152.0 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 M5.7 one earlier?

No. This magnitude 4.1 earthquake is an aftershock of the larger magnitude 5.7 mainshock that occurred earlier 271 km WSW of Tual, Indonesia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

Understanding This Data

Magnitude 4.1 earthquakes are often felt but rarely cause damage.
