At divergent and transform boundaries.
divergent plate boundaries
focus
Frequent shallow earthquakes
Shallow focus earthquakes occur at the mid ocean ridges because the thin lithosphere found there is to weak to allow a large amount of strain to build up and cause larger earthquakes.
earthquakes usually occur at tectonic plate boundaries
divergent
At divergent and transform boundaries.
Shallow focus earthquakes occur at depths of 70 km with magnitudes ranging from 1-5. Deep focus earthquakes occur at depths from 300-700 km and magnitudes from 6-10.
within or adjacent to trenches
All three type of Earthquakes (Shallow-seated, Medium-seated and Deep-seated) occur only at the Convergent plate boundary. At divergent plate boundary we find mostly Shallow-seated Earthquakes only.
Shallow focus earthquakes generally cause more damage.
Earthquakes that happen in shallow water cause tsunami and other side affects like landslides.
The lithosphere is where earthquakes occur.
Earthquakes occur at all plate boundaries.
