M5.0 Earthquake 150 km S of Sofifi, Indonesia — February 26, 2021
2021-02-26 11:02:31 UTC (2021-02-26) · approx. 7:02 PM UTC+8 local
On February 26, 2021 at 11:02 UTC, a magnitude 5.0 shallow crustal earthquake struck 150 km S of Sofifi, Indonesia, at a depth of 10.0 km and coordinates -0.6146°, 127.4456°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
