In addition to the damage caused directly by seismic vibrations, list three other types of destructive events that can be triggered by earthquakes. Fire, Land slide, Tsunami 6. Describe the composition and physical properties of the crust. Crust is thin, rocky, & outer layer of Earth.n addition to the damage caused directly by seismic vibrations, list three other types of destructive events that can be triggered by earthquakes.

Tsunamis occur after an earthquake. The earthquake can occur under a city (ex. The New Madrid Missouri fault line; or the Los Angeles area's fault lines), but many occur on the ocean or sea floor.n average, two tsunamis occur per year. Approximately every 15  years a destructive, ocean-wide tsunami occurs. Tsunami's occur  when an earthquake causes a significant ver â¦ tical deformation of the  seafloor.
