M5.6 Earthquake 11 km NE of Sukabumi, Indonesia — November 21, 2022
2022-11-21 06:21:07 UTC (2022-11-21) · approx. 1:21 PM UTC+7 local
Felt by 169 people across surrounding communities. Maximum shaking intensity MMI 8.5 (violent).
On November 21, 2022 at 06:21 UTC, a magnitude 5.6 shallow crustal earthquake struck 11 km NE of Sukabumi, Indonesia, at a depth of 10.0 km and coordinates -6.8360°, 106.9968°. The earthquake was reported felt by 169 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 8.5 (violent). The USGS PAGER system issued a orange alert level for this event, indicating regional impact possible. This earthquake was detected by 154 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 1086, making it one of the most significant global earthquakes in recent days. The nearest populated place is Cianjur (population 0).
Physical scale: An earthquake of magnitude 5.6 releases seismic energy equivalent to roughly 4 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 4.4 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 5.6 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 5.6 event is significantly smaller than that historical record.
