On February 2, 2022 at 19:29 UTC, a magnitude 4.7 shallow crustal earthquake struck 105 km SW of Padangsidempuan, Indonesia, at a depth of 59.1 km and coordinates 0.7928°, 98.5208°.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — 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 77 km SSW of Sibolga, 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.

The epicenter is located in Indonesia, a region characterized by the convergence of the Indo-Australian, Eurasian, and Philippine Sea plates, forming the Sunda-Banda arc system. The nearest mapped fault system is the Sunda megathrust. View all earthquakes in Indonesia.

Common Questions

How strong was the magnitude 4.7 earthquake near Padangsidempuan, Indonesia?

The magnitude 4.7 earthquake that struck 105 km SW of Padangsidempuan, Indonesia on February 2, 2022 at 19:29 UTC had a depth of 59.1 km. For context, this was a light earthquake commonly felt near the epicenter.

Where did the earthquake occur?

The earthquake epicenter was located at 0.7928°, 98.5208°, which is 105 km SW of Padangsidempuan, Indonesia. View all earthquakes in Indonesia.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.7 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 4.7 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 77 km SSW of Sibolga, Indonesia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

Has Indonesia had earthquakes this big before?

The largest recorded earthquake in Indonesia was the M9.1 Indian Ocean earthquake of December 26, 2004. Today's magnitude 4.7 event is significantly smaller than that historical record.
