1. Observation of seismic site effects
The seismic wave generated by faults propagates through the earth's crust. It attenuates as it travels, particularly as its energy is spread over a larger surface area.
Depending on the configuration and physical nature of the surface medium, it can be locally modified: amplified or reduced (de-amplified) in amplitude, frequency and duration.
An earthquake corresponds to the sudden rupture of a fault, which can be more than 500 km long, over an area of more than 10,000 km

, and with a differential displacement along the fault of up to several meters.
Rupture along the fault leads to several physical phenomena that can be classified as follows...
