A micro magnitude 2.6 earthquake struck near OFFSHORE COQUIMBO, CHILE on Tuesday, September 22, 2026 at 08:30:50 PM UTC. This shallow crustal event (42.9 km depth) released energy equivalent to approximately 120 kg of TNT. Here is the verified CSN telemetry, live epicenter map, and ground shaking assessment.

A magnitude 2.6 event is classified as a micro earthquake. Micro-earthquakes are rarely felt by humans and are typically recorded only by sensitive seismometers.
Felt by almost no one except under extraordinarily favorable conditions.

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:
This event occurred along the Peru-Chile (Andean) Subduction Zone, where the dense oceanic Nazca Plate slides eastward and plunges underneath the continental South American Plate at roughly 6 to 8 centimeters per year. This megathrust boundary is one of the most seismically active fault zones on Earth.
Originating at a depth of 42.9 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.
Micro-tremors and minor events of this scale are part of ongoing background tectonic relaxation. While isolated micro-aftershocks may occur, the likelihood of a damaging secondary event remains statistically low under normal seismic conditions.
