M4.7 Earthquake 166 km ENE of Tual, Indonesia — June 15, 2021
2021-06-15 09:55:27 UTC (2021-06-15) · approx. 6:55 PM UTC+9 local
On June 15, 2021 at 09:55 UTC, a magnitude 4.7 shallow crustal earthquake struck 166 km ENE of Tual, Indonesia, at a depth of 10.0 km and coordinates -5.1770°, 134.1857°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
