On March 5, 2022 at 12:02 UTC, a magnitude 5.5 shallow crustal earthquake struck near northern Sumatra, Indonesia, at a depth of 42.0 km and coordinates 4.6517°, 95.0249°. The earthquake was reported felt by 3 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.7 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Lhokkruet (population 0).

Physical scale: An earthquake of magnitude 5.5 releases seismic energy equivalent to roughly 3 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.8 km — a useful intuition for the size of the slip patch on the fault.

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 5.5 earthquake near northern Sumatra, Indonesia?

The magnitude 5.5 earthquake that struck near northern Sumatra, Indonesia on March 5, 2022 at 12:02 UTC had a depth of 42.0 km. It was felt by 3 people with maximum shaking intensity of MMI 3.7 (light). For context, this was a moderate earthquake that could be widely felt.

Where did the earthquake occur?

The earthquake epicenter was located at 4.6517°, 95.0249°, which is near northern Sumatra, Indonesia. The nearest populated place is Lhokkruet (population 0). View all earthquakes in Indonesia.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.5 earthquakes can continue for days to weeks and gradually diminish over time.

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 5.5 event is significantly smaller than that historical record.
