On April 15, 2024 at 10:43 UTC, a magnitude 5.4 intermediate depth earthquake struck 106 km SSW of Kokopo, Papua New Guinea, at a depth of 72.0 km and coordinates -5.2266°, 151.8920°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 105 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 Rabaul (population 8,074).

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.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.4 earthquakes can continue for days to weeks 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 5.4 event is significantly smaller than that historical record.
