2026-10-19 09:00:39 UTC (2 hours ago) · approx. 5:00 PM UTC+8 local
On October 19, 2026 at 09:00 UTC, a magnitude 4.7 shallow crustal earthquake struck 163 km WNW of Tobelo, Indonesia, at a depth of 49.0 km and coordinates 2.4339°, 126.7168°. This earthquake was detected by 36 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
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.
