M6.7 Earthquake 166 km W of Pariaman, Indonesia — March 13, 2022
2022-03-13 21:09:22 UTC (2022-03-13) · approx. 4:09 AM UTC+7 local
Felt by 20 people across nearby locations. Maximum shaking intensity MMI 6.5 (very strong).
On March 13, 2022 at 21:09 UTC, a magnitude 6.7 shallow crustal earthquake struck 166 km W of Pariaman, Indonesia, at a depth of 28.0 km and coordinates -0.6294°, 98.6259°. The earthquake was reported felt by 20 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.5 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Sikabaluan (population 0).
Physical scale: An earthquake of magnitude 6.7 releases seismic energy equivalent to roughly 169 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 25 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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 6.7 earthquakes can continue for weeks to months 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 6.7 event is significantly smaller than that historical record.
