M5.0 Earthquake 133 km WSW of Labuan, Indonesia — August 25, 2020
2020-08-25 23:27:58 UTC (2020-08-25) · approx. 6:27 AM UTC+7 local
On August 25, 2020 at 23:27 UTC, a magnitude 5.0 shallow crustal earthquake struck 133 km WSW of Labuan, Indonesia, at a depth of 35.0 km and coordinates -6.6509°, 104.6542°.
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.
