On July 14, 2026 at 09:52 UTC, a magnitude 4.4 shallow crustal earthquake struck 25 km SE of Tambolaka, Indonesia, at a depth of 48.7 km and coordinates -9.5899°, 119.3992°.

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 5.1 mainshock that occurred 1 day ago 27 km SSE of Tambolaka, Indonesia. Since the mainshock, the USGS has recorded 3 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 Tambolaka, Indonesia?

The magnitude 4.4 earthquake that struck 25 km SE of Tambolaka, Indonesia on July 14, 2026 at 09:52 UTC had a depth of 48.7 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 M5.1 one earlier?

No. This magnitude 4.4 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 27 km SSE of Tambolaka, 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.
