M4.9 Earthquake 2 km WSW of Granada, Spain — August 18, 2026
2026-08-18 08:37:44 UTC (1 hour ago) · approx. 8:37 AM UTC+0 local
Felt by 18 people across nearby locations. Aftershock of the M5.2 mainshock.
On August 18, 2026 at 08:37 UTC, a magnitude 4.9 shallow crustal earthquake struck 2 km WSW of Granada, Spain, at a depth of 10.0 km and coordinates 37.1786°, -3.6311°. This earthquake was detected by 58 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 379, 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.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.2 mainshock that occurred 3 days ago 1 km SW of Otura, Spain. Since the mainshock, the USGS has recorded 3 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 4.9 earthquake near Granada, Spain?
The magnitude 4.9 earthquake that struck 2 km WSW of Granada, Spain on August 18, 2026 at 08:37 UTC had a depth of 10.0 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 37.1786°, -3.6311°, which is 2 km WSW of Granada, Spain.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.9 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.2 one earlier?
No. This magnitude 4.9 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 1 km SW of Otura, Spain. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
