How does an earthquake occur on a fault line?

How does an earthquake occur on a fault line?

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. When the rocks break, the earthquake occurs.

Do earthquakes occur near fault lines?

Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.

The current building code (since IBC 2012) is based on a “risk-targeted” concept. The design hazard values in the code are developed to create a uniform risk at all locations where buildings designed to these values have a 1% probability of collapse in 50 years (the typical life span of a building).

Can Apartments collapse?
