M4.4 Earthquake 80 km ESE of Bitung, Indonesia — August 24, 2025
2025-08-24 17:52:18 UTC (2025-08-24) · approx. 1:52 AM UTC+8 local
On August 24, 2025 at 17:52 UTC, a magnitude 4.4 intermediate depth earthquake struck 80 km ESE of Bitung, Indonesia, at a depth of 72.0 km and coordinates 1.0590°, 125.7479°.
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 5.2 mainshock that occurred 10 days ago 117 km SE of Bitung, Indonesia. Since the mainshock, the USGS has recorded 1 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 Bitung, Indonesia?
The magnitude 4.4 earthquake that struck 80 km ESE of Bitung, Indonesia on August 24, 2025 at 17:52 UTC had a depth of 72.0 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 4.4 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.2 one earlier?
No. This magnitude 4.4 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 117 km SE of Bitung, Indonesia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
