a real world example of a disaster is the tsunami they expect to happen at the cascadia subduction zone. they suspect that a 9.0 earthquake will result in a tsunami. they estimate that a total of 246,500 people will die during this disaster. below is a picture of this.
*subduction is when oceanic crust slides underneath continental crust. when the oceanic crust gets pulled down(because its more dense than the continental crust) to the mantle, creating a trench, the waterlogged crust heats up and water pushes up through the crust to create volcanoes.*
transform boundaries are when the tectonic plates move past each other, creating shear.
this picture is demonstrating shear
