WebAll trenches are associated with zones of earthquake foci. Along the periphery of the Pacific Ocean, earthquakes occur close to and landward of the trenches, at depths within the Earth of 55 km (34 miles) or less. With increased landward distance away from the trenches, earthquakes occur at greater and greater depths--500 km or more.

There are the sunlight zone, the twilight zone, the midnight zone, the abyss, and the trenches. The striking difference between the five layers is a matter of depth.
