2023-01-24 16:10:15 UTC (2023-01-24) · approx. 1:10 AM UTC+9 local
On January 24, 2023 at 16:10 UTC, a magnitude 5.2 shallow crustal earthquake struck 210 km NNE of Tobelo, Indonesia, at a depth of 11.0 km and coordinates 3.5550°, 128.5402°. This earthquake was detected by 74 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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.
