M5.4 Earthquake 184 km ESE of Kimbe, Papua New Guinea — April 5, 2025
2025-04-05 09:04:40 UTC (2025-04-05) · approx. 7:04 PM UTC+10 local
On April 5, 2025 at 09:04 UTC, a magnitude 5.4 shallow crustal earthquake struck 184 km ESE of Kimbe, Papua New Guinea, at a depth of 10.0 km and coordinates -6.4253°, 151.5526°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 62 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 449, placing it among routine seismic activity. The nearest populated place is Kimbe (population 18,847).
Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Papua New Guinea, a region characterized by the collision and subduction of the Pacific, Australian, and Solomon Sea plates. View all earthquakes in Papua New Guinea.
