Which of the following occurs within 70-300 km of the surface? Intermediate focus EQ's Deep focus EQ's Shallow focus EQ's

The correct answer is Intermediate focus EQ's.<br /><br />Earthquakes that occur within 70-300 km of the surface are classified as intermediate focus earthquakes. These earthquakes occur at a depth that is between shallow and deep focus earthquakes. Shallow focus earthquakes occur at depths less than 70 km, while deep focus earthquakes occur at depths greater than 300 km. Intermediate focus earthquakes are typically associated with subduction zones, where one tectonic plate is being forced beneath another.
