M6.9 Earthquake 184 km ESE of Kimbe, Papua New Guinea — April 4, 2025
2025-04-04 20:04:38 UTC (2025-04-04) · approx. 6:04 AM UTC+10 local
Felt by 13 people across nearby locations. Maximum shaking intensity MMI 6.0 (strong).
On April 4, 2025 at 20:04 UTC, a magnitude 6.9 shallow crustal earthquake struck 184 km ESE of Kimbe, Papua New Guinea, at a depth of 9.0 km and coordinates -6.3025°, 151.6257°. The earthquake was reported felt by 13 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.0 (strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 333 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 739, making it a moderate-impact event. The nearest populated place is Kandrian (population 1,014).
Physical scale: An earthquake of magnitude 6.9 releases seismic energy equivalent to roughly 338 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 35 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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 6.9 earthquakes can continue for weeks to months and gradually diminish over time.
Has Papua New Guinea had earthquakes this big before?
The largest recorded earthquake in Papua New Guinea was the M8.0 New Britain earthquake of July 18, 1971. Today's magnitude 6.9 event is significantly smaller than that historical record.
