2026-08-28 00:43:06 UTC (45 min ago) · approx. 8:43 AM UTC+8 local
On August 28, 2026 at 00:43 UTC, a magnitude 4.6 intermediate depth earthquake struck 119 km NNW of Ternate, Indonesia, at a depth of 74.0 km and coordinates 1.7526°, 126.8948°. This earthquake was detected by 43 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
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.
