M4.5 Earthquake 77 km NW of Maumere, Indonesia — June 4, 2020
2020-06-04 23:12:34 UTC (2020-06-04) · approx. 7:12 AM UTC+8 local
On June 4, 2020 at 23:12 UTC, a magnitude 4.5 shallow crustal earthquake struck 77 km NW of Maumere, Indonesia, at a depth of 10.0 km and coordinates -8.1267°, 121.7144°.
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.
