15+ Diagram Shallow Focus Earthquakes Background. They occur almost exclusively at convergent boundaries in association with subducted oceanic lithosphere. Shallow‐focus earthquakes occur along transform boundaries where two plates move past each other.

World Wide Patterns Of Seismicity Geohazards Earthquakes from sites.google.com

Italy's earthquake was a lot weaker than the one in myanmar, but it did far more damage because it happened at a shallower depth. Causes, difference between shallow and deep focus earthquake. Use colored pens, pencils, or crayons to plot the earthquakes from table 1 on the graph on the next page.

The focus of an earthquake is the actual point underground where rocks break.

In fact, the great majority of earthquake foci are shallow. Shallow focus earthquakes are found within the earth's outer crustal layer, while deep focus earthquakes occur within the deeper subduction zones of the earth. The earthquakes are shallow because the new plates are thin. Italy's earthquake was a lot weaker than the one in myanmar, but it did far more damage because it happened at a shallower depth.
