2022-09-15 15:24:48 UTC (2022-09-15) · approx. 10:24 PM UTC+7 local
On September 15, 2022 at 15:24 UTC, a magnitude 4.8 shallow crustal earthquake struck 147 km SW of Padang, Indonesia, at a depth of 19.0 km and coordinates -2.0533°, 99.6071°. This earthquake was detected by 131 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
