shallow focus (0 - 20 km) earthquakes occur in which location?
mid - ocean ridges
transform boundaries
subduction zones
all of the above
previous

Explanation:

• Mid - ocean ridges: Tectonic plates are moving apart, and the stress release causes shallow - focus earthquakes.
• Transform boundaries: Plates slide past each other, and the frictional interaction leads to shallow - focus earthquakes.
• Subduction zones: Although deeper earthquakes can occur in subduction zones, the initial interaction and stress build - up near the surface (shallow part of the subduction process) can also cause shallow - focus earthquakes.

Answer:

All of the above
