Abstract:
By studying the temporal characteristics of crustal deformation, u-nderground hydrochemical parame- ters, distributions of earthquakes and ratio of P-wave to S-wave before Jingyang earthquake with ML= 5.2, it is found that the crustal deformation, underground fluid and seismicity in this region exhibits different properties in long, medium and short terms before the earthquake. Thus, some anomalies do exist before the earthquake, and the forecast of the earthquake may be made.
