A light magnitude 4.6 earthquake struck 1 km NNW of Katochí, Greece on Tuesday, September 8, 2026 at 07:46:29 AM UTC. This shallow crustal event (10.0 km depth) released energy equivalent to approximately 120 tons of TNT. Here is the verified US telemetry, live epicenter map, and ground shaking assessment.

A magnitude 4.6 event is classified as a light earthquake. Noticeable shaking of indoor objects and rattling doors/windows. Generally causes none to slight non-structural damage in older buildings.
Difficult to stand. Damage negligible in good buildings; slight to moderate in ordinary structures.
Felt only by a few persons at rest, especially on upper floors.

Your immediate response verifies shaking boundaries and helps ground-truth instrumental models.
Earthquake strength is measured on a logarithmic scale. Compare this event with the full seismic scale:
Because seismic scales are logarithmic, each whole integer increase represents:
The Mediterranean region lies in the active collision zone of the African, Arabian, and Eurasian tectonic plates. In Anatolia, the westward extrusion of the Anatolian Microplate along the North Anatolian and East Anatolian strike-slip faults generates powerful, shallow-focus earthquakes.
Originating at a depth of 10.0 km (Earth's Crust (0–70 km)), this rupture occurred occurred within the brittle upper crust. shallow earthquakes produce the highest peak ground acceleration and the sharpest surface shaking.
Seismologists note that minor aftershocks remain common in the 24 to 48 hours following tremors of magnitude 4.6. According to statistical seismic models, there is roughly a 5% probability of a subsequent event of equal or greater strength occurring in the same fault zone. Residents in Greece are advised to check living spaces for unsecured items.
