Shaking of the ground caused by the passage of seismic waves, especially surface waves near the epicentre of the earthquake are responsible for the most damage during an earthquake. The intensity of ground shaking depends on:
conditions of the local geology influence evenuts: solid bedrock is far less subject to intense shaking than loose sediment;duration and intensity of the earthquake are subject generally to the size of the earthquake;distance: ss the distance from the epicentre drops off so the intensity of the shaking decreases. This depends on the type of material underlying the area. There are however some exceptions. The 1985 Earthquake in Mexico city (magnitude 8.1) had its epicentre 350 Kms away to the south on the coast. Damage to city was extensive as Mexico city is built on a former lake made up of soft unconsolidated sediment (see: Liquefaction further down).
