On July 12, 2020 at 22:38 UTC, a magnitude 5.4 intermediate depth earthquake struck 5 km WNW of El Crucero, Nicaragua, at a depth of 159.3 km and coordinates 12.0163°, -86.3553°. The earthquake was reported felt by 7 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.3 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Masachapa (population 5,000).

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.
