∙ 12y agoThe earthquakes with the deepest foci occur at subduction boundaries. This is because the down going cold lithospheric slab is brittle as opposed to the surrounding ductile mantle material. As the material is brittle at greater depths than would normally occur this allows earthquakes to occur at greater depths than anywhere else. In general the depth of the earthquake in a subducting slab will increase with increased distance from the subduction zone / trench.

or farther away from a trench

What type of earthquakes occur farther inland than other earthquakes?
deep focus
Where would the deepest earthquakes most likely occur?
Near to subduction zones where stresses in the subducting crustal plate can cause earthquakes with very deep hypocentres.
What occurs along ocean trenches but not along mid ocean ridges that accounts for the occurrence's of deep focus earthquakes?
Subduction of oceanic crust. The Earthquakes occur at depth in the descending slab.
What regions do earthquakes mostly occur?
earthquakes usually occur at tectonic plate boundaries
What must be passed for earthquakes to occur?
seismic unit
Where does deep earthquakes occur?
in the core
What type of earthquakes occur farther inland than other earthquakes?
deep focus
In what type of boundary do deep earthquakes occur in?
They occur at convergent boundaries where subduction is occurring.
What is the difference between shallow focus earthquakes and deep focus earthquakes?
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.
Do deep focus earthquakes occur as a plate moves deeper into the mantle?
yes they do
Why have earthquakes occurred at night?
Earthquakes are caused by processes that occur deep underground. It does not make a difference whether it is day or night.
Where do very deep large magnitude earthquakes occur?
At convergent boundaries where subduction is occurring.
Where do most deep-focus earthquakes occur?
At convergent plate boundaries where subduction is occurring.
Why do the most deep earthquakes occur at convergent boundries?
because so much pressure is produced
Where would the deepest earthquakes most likely occur?
Near to subduction zones where stresses in the subducting crustal plate can cause earthquakes with very deep hypocentres.
What biome do earthquakes occur in?
The lithosphere is where earthquakes occur.
What is a deep earthquake?
Deep earthquakes occur in a region of the mantle called the Benioff zone, where seismic activity follows the interaction between a subducting plate and the upper mantle.
