2026-01-12 19:18:06 UTC (2026-01-12) · approx. 4:18 AM UTC+9 local
On January 12, 2026 at 19:18 UTC, a magnitude 4.5 shallow crustal earthquake struck 113 km WSW of Abepura, Indonesia, at a depth of 64.3 km and coordinates -2.9085°, 139.6644°. This earthquake was detected by 52 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
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.
