    Abstract: A system and method instantly on-site analyze seismic acceleration signals measured from a primary wave of an earthquake and at a detecting site. The system includes an embedded computing host and a signal preprocessing module. Hardware preprocessing is executed on the seismic acceleration signals; and whether the earthquake is a seismic event is able to be determined according to a seism determining logic. Seismic acceleration signals are converted into ground velocities and ground displacements to obtain a peak ground displacement. A seismic fracture time parameter is calculated through the ground velocities and ground displacements and then a seismic magnitude of the earthquake is obtained. According to the peak ground displacement and the seismic magnitude, an epicentral distance is further calculated. Then a peak ground acceleration of the earthquake's shear wave at the detection site is able to be obtained through the seismic magnitude and the epicentral distance.
