Earthquake is a major cause of human disasters, building collapses, fires, tsunamis (seismic sea waves), and volcano eruptions, etc. The Earth's crust is made up of several thin, wide, rigid plates that are in regular motion. Seismic vibrations are produced on the Earth's surface due to the sudden rupture of plates, releasing the accumulated deformation energy [1]. Numerous techniques based on the measurement of the velocity and acceleration of seismic vibrations have been reported in the literature [2]-[5]. Existing methods,usually only measure acceleration and fail to record its peak,values ​​with high precision [5]-[7]. Furthermore, the response of existing methods is on the order of several seconds [5], [8]. Generally, before an earthquake, preshocks occur, the structure of which bears a strong resemblance to the main shock [9]-[13]. The results revealed that foreshocks are the best prediction of earthquakes [10]-[12]. Foreshocks are generated and measured in the same way as the mainshock. However, the magnitude of speed and acceleration ...
