2026-05-12 18:10:22 UTC (3 hours ago) · approx. 3:10 AM UTC+9 local
On May 12, 2026 at 18:10 UTC, a magnitude 4.7 intermediate depth earthquake struck 128 km N of Tobelo, Indonesia, at a depth of 72.6 km and coordinates 2.8835°, 127.9058°. This earthquake was detected by 121 seismic stations with excellent 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.
