FAQ for Earthquake

10. What is the definition of "the observation of strong ground motion"?

Based on the earthquake disaster experiences from the past, the cause of earthquake disaster is mainly due to the destruction of buildings by strong ground motion, resulting in the casualties and loss of property. The ground motion, caused by seismic waves, can have different responses under different geological conditions. The observations of these different responses to the ground motion using a strong-motion seismograph can provide better understanding about the characteristics of the strong ground movement and its influence on buildings.
