How does an earthquake cause structural damage?
Several factors determine the structural damage from an earthquake including, the proximity to active earthquake faults; the building construction (type of building, materials used, and quality of workmanship); the local site conditions (type and condition of soil, slope of the land, and fill material); and the geologic structure of the earth beneath the structure.

About Earthquake
An Earthquake (also known as a quake or tremor) is a shift in the earth's crust that releases a substantial amount of energy. The size, type and frequency of an earthquake is measured by its seismic activity. The shifting of the surface during an earthquake can cause catastrophic damage to any nearby population. The magnitude of an earthquake is measured on the Richter scale. The Richter scale rates the size of the earthquake from 1 to 10+ with 10+ being the worst.
