Strong Motion Networks
Strong Motion Seismology may be referred to as science and technology based on strong motion network data and earthquake disaster records near earthquake sources. The objective of creating strong motion networks is to generate data to study source dynamics of generated ground motions from seismic sources. A further objective is the analysis of seismic-wave propagation effects due to complex geological structures in propagation-path from source to site, including wave attenuation and scattering. Finally, the amplification and de-amplification of seismic motions due to surface geological and topography, including nonlinear behaviour of soils for strong motions. Then as a goal, it is to develop methodologies (a.k.a. GMPEs) of predicting strong ground motions from seismic sources related to active faults and subduction-zones with high probability of earthquake occurrence in order to mitigate earthquake disaster.
The data generated from Strong Motion Networks are used for earthquake emergency response, for improving engineering designs, and for research in seismology. For earthquake emergency response, applications such as the ShakeMaps use strong-motion data as input and generate near-real time information on the levels of ground shaking and loss assessment for emergency responders. Structural and earthquake engineers use strong motion recordings to verify or improve design codes.
