Why Did This Earthquake Happen?
Earthquakes occur when stress built up along tectonic plate boundaries or faults is suddenly released. The 2013 Sea of Okhotsk Earthquake region sits near active geological boundaries where plates are constantly moving, colliding, or sliding past each other.
At a depth of 598.1 km, this seismic event originated deep within the Earth's mantle. The energy released traveled outward as seismic waves, causing the shaking felt at the surface.
