2021-07-19 00:55:43 UTC (2021-07-19) · approx. 8:55 AM UTC+8 local
On July 19, 2021 at 00:55 UTC, a magnitude 5.3 intermediate depth earthquake struck 61 km SSE of Gorontalo, Indonesia, at a depth of 159.2 km and coordinates 0.0033°, 123.2252°.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.
