On April 12, 2025 at 16:02 UTC, a magnitude 4.4 intermediate depth earthquake struck 168 km N of Tobelo, Indonesia, at a depth of 82.9 km and coordinates 3.2534°, 127.9736°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 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 5.4 mainshock that occurred 21 days ago 162 km NNW of Tobelo, 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 4.4 earthquake near Tobelo, Indonesia?

The magnitude 4.4 earthquake that struck 168 km N of Tobelo, Indonesia on April 12, 2025 at 16:02 UTC had a depth of 82.9 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 4.4 earthquakes can continue for several days and gradually diminish over time.

Is this the same earthquake as the M5.4 one earlier?

No. This magnitude 4.4 earthquake is an aftershock of the larger magnitude 5.4 mainshock that occurred earlier 162 km NNW of Tobelo, Indonesia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

Understanding This Data

Magnitude 4.4 earthquakes are often felt but rarely cause damage.
