       What is an Earthquake? An earthquake is the shaking caused by the rupture (breaking) and subsequent displacement of rocks (one body of rock moving with respect to another) beneath Earth’s surface.. A body of rock that is under stress becomes deformed. When the rock can no longer withstand the deformation, it breaks and the two sides slide past each ://   Tabletop exercises are table-based activities typically held in an informal setting and presented by the Facilitator. There is no hands-on practice or field work. This type of exercise is intended to generate discussion of various issues regarding a hypothetical, simulated emergency.
