2024-02-14 11:40:22 UTC (2024-02-14) · approx. 8:40 PM UTC+9 local
Felt by 1 person across nearby locations.
On February 14, 2024 at 11:40 UTC, a magnitude 6.0 shallow crustal earthquake struck 171 km NNE of Colonia, Micronesia, at a depth of 14.0 km and coordinates 11.0047°, 138.5725°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.8 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 143 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 554, placing it among routine seismic activity. The nearest populated place is Rumung (population 0).
Physical scale: An earthquake of magnitude 6.0 releases seismic energy equivalent to roughly 15 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 8.3 km — a useful intuition for the size of the slip patch on the fault.
