M4.6 Earthquake 295 km W of Tual, Indonesia — April 22, 2022
2022-04-22 19:46:18 UTC (2022-04-22) · approx. 4:46 AM UTC+9 local
On April 22, 2022 at 19:46 UTC, a magnitude 4.6 intermediate depth earthquake struck 295 km W of Tual, Indonesia, at a depth of 186.8 km and coordinates -5.8322°, 130.0961°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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.
