M4.8 Earthquake 34 km S of Puerto San José, Guatemala — November 10, 2026
2026-11-10 15:23:58 UTC (44 min ago) · approx. 9:23 AM UTC-6 local
Aftershock of the M5.6 mainshock.
On November 10, 2026 at 15:23 UTC, a magnitude 4.8 shallow crustal earthquake struck 34 km S of Puerto San José, Guatemala, at a depth of 58.5 km and coordinates 13.6155°, -90.8190°. This earthquake was detected by 122 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
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.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.6 mainshock that occurred 1 hour ago 43 km S of Puerto San José, Guatemala. Since the mainshock, the USGS has recorded 1 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.8 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.6 one earlier?
No. This magnitude 4.8 earthquake is an aftershock of the larger magnitude 5.6 mainshock that occurred earlier 43 km S of Puerto San José, Guatemala. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
