Felt by 10 people across nearby locations. Maximum shaking intensity MMI 4.6 (moderate).
On February 16, 2023 at 06:50 UTC, a magnitude 5.4 shallow crustal earthquake struck 37 km WSW of Bombardopolis, Haiti, at a depth of 10.0 km and coordinates 19.5974°, -73.6826°. The earthquake was reported felt by 10 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.6 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 113 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 454, placing it among routine seismic activity. The nearest populated place is Bombardopolis (population 1,974).
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.
