M5.8 Earthquake 69 km WSW of Río Grande, Panama — July 15, 2020
2020-07-15 21:39:40 UTC (2020-07-15) · approx. 4:39 PM UTC-5 local
Felt by 24 people across nearby locations. Maximum shaking intensity MMI 6.9 (very strong).
On July 15, 2020 at 21:39 UTC, a magnitude 5.8 shallow crustal earthquake struck 69 km WSW of Río Grande, Panama, at a depth of 6.6 km and coordinates 7.4645°, -81.9100°. The earthquake was reported felt by 24 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.9 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Puerto Vidal (population 0).
Physical scale: An earthquake of magnitude 5.8 releases seismic energy equivalent to roughly 8 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 6.1 km — a useful intuition for the size of the slip patch on the fault.
