M4.8 Earthquake in the Falkland Islands region — July 30, 2020
2020-07-30 07:09:39 UTC (2020-07-30) · approx. 3:09 AM UTC-4 local
On July 30, 2020 at 07:09 UTC, a magnitude 4.8 shallow crustal earthquake struck in the Falkland Islands region, at a depth of 10.0 km and coordinates -54.1389°, -55.0602°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
