2024-10-14 21:30:19 UTC (2024-10-14) · approx. 6:30 AM UTC+9 local
On October 14, 2024 at 21:30 UTC, a magnitude 4.5 shallow crustal earthquake struck 176 km WSW of Abepura, Indonesia, at a depth of 10.0 km and coordinates -3.2523°, 139.1898°. This earthquake was detected by 45 seismic stations with excellent 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.
