A magnitude 3.3 event is classified as a minor earthquake. Often felt by people indoors, especially on upper floors. Hanging objects may swing slightly; structural damage is extremely rare.
The epicenter occurred in a remote or offshore marine sector with no major population centers situated within the primary ground shaking perimeter.

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:
Earthquakes occur when elastic stress built up along tectonic plate boundaries, regional fault lines, or crustal fractures suddenly exceeds the friction holding the rock masses together. When the fault slips, accumulated energy radiates outward in all directions as high-velocity seismic waves.
Originating at a depth of 40.0 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.
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.
