2021-11-19 20:07:03 UTC (2021-11-19) · approx. 4:07 AM UTC+8 local
On November 19, 2021 at 20:07 UTC, a magnitude 4.0 shallow crustal earthquake struck 76 km ESE of Manay, Philippines, at a depth of 35.0 km and coordinates 6.8981°, 127.1562°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
