Why the focus of earthquakes can be very deep subduction boundaries?

Subducted crust is brought to the point of melting as it enters the mantle. As a liquid highly entrained with gas, it will attempt to rise through any weak points in the crust. When it reaches the surface, it will form a volcano.

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 is platonic earthquake?
Plutonic earthquakes are deep focus earthquakes.
What are the effects of deep focus earthquakes?
Very little, as the earthquake occurs deep underground, hence the deep focus.
What types of plate boundaries are associated with deep earthquakes?
All of them. For example: the earthquake of 2010 in Chile happened along a convergent fault while the 2010 earthquake in Haiti happened along a transform fault. Source: I am just a genius...
What type of earthquakes occur farther inland than other earthquakes?
deep focus
Where do most deep-focus earthquakes occur?
At convergent plate boundaries where subduction is occurring.
In what type of boundary do deep earthquakes occur in?
They occur at convergent boundaries where subduction is occurring.
Where do very deep large magnitude earthquakes occur?
At convergent boundaries where subduction is occurring.
Deep-focus earthquakes are associated with what plate boundaries?
destructive or convergent boundaries
What is one suggested cause of deep focus earthquakes?
Stress due to the subduction of tectonic plates into Earth's mantle.
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.
4 At what type of plate boundary do you find most deep-focus earthquakes?
The most deep focused earthquakes would be found at transform boundaries. The shallow focused earthquakes would be found at Divergent boundaries. And the intermediate focused earthquakes would be found at Convergent boundaries. By: A ninth grader.
What is platonic earthquake?
Plutonic earthquakes are deep focus earthquakes.
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.
What are the effects of deep focus earthquakes?
Very little, as the earthquake occurs deep underground, hence the deep focus.
What types of plate boundaries are associated with deep earthquakes?

What causes more damage shallow or deep focus earthquakes?
Shallow focus earthquakes generally cause more damage.
