2021-06-02 19:07:01 UTC (2021-06-02) · approx. 4:07 AM UTC+9 local
On June 2, 2021 at 19:07 UTC, a magnitude 4.5 intermediate depth earthquake struck 51 km SSE of Amahai, Indonesia, at a depth of 121.9 km and coordinates -3.7608°, 129.1236°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — 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.
