M4.9 Earthquake in the Mariana Islands region — January 19, 2026
2026-01-19 17:59:24 UTC (2026-01-19) · approx. 2:59 AM UTC+9 local
On January 19, 2026 at 17:59 UTC, a magnitude 4.9 shallow crustal earthquake struck in the Mariana Islands region, at a depth of 43.0 km and coordinates 12.4911°, 141.6318°. This earthquake was detected by 66 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
