M4.9 Earthquake 101 km SSE of Palekastro, Greece — November 3, 2026
2026-11-03 11:03:47 UTC (2 hours ago) · approx. 1:03 PM UTC+2 local
Aftershock of the M5.3 mainshock.
On November 3, 2026 at 11:03 UTC, a magnitude 4.9 shallow crustal earthquake struck 101 km SSE of Palekastro, Greece, at a depth of 45.7 km and coordinates 34.3254°, 26.5713°. This earthquake was detected by 120 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.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.3 mainshock that occurred 20 hours ago 81 km SSE of Palekastro, Greece. Since the mainshock, the USGS has recorded 2 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
The epicenter is located in Greece, a region characterized by the Hellenic subduction zone, where the African Plate subducts northward beneath the Aegean at roughly 35 mm per year. The nearest mapped fault system is the Hellenic Trench. View all earthquakes in Greece.

Common Questions
How strong was the magnitude 4.9 earthquake near Palekastro, Greece?
The magnitude 4.9 earthquake that struck 101 km SSE of Palekastro, Greece on November 3, 2026 at 11:03 UTC had a depth of 45.7 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 34.3254°, 26.5713°, which is 101 km SSE of Palekastro, Greece. View all earthquakes in Greece.
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 M5.3 one earlier?
No. This magnitude 4.9 earthquake is an aftershock of the larger magnitude 5.3 mainshock that occurred earlier 81 km SSE of Palekastro, Greece. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
Has Greece had earthquakes this big before?
The largest recorded earthquake in Greece was the M8.5 Crete earthquake of June 29, 1303. Today's magnitude 4.9 event is significantly smaller than that historical record.
