2026-02-17 19:24:21 UTC (2026-02-17) · approx. 3:24 AM UTC+8 local
On February 17, 2026 at 19:24 UTC, a magnitude 4.6 intermediate depth earthquake struck 67 km SSE of Modisi, Indonesia, at a depth of 80.1 km and coordinates -0.1307°, 124.6068°. This earthquake was detected by 81 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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.
