Abstract

Abstract

The authors analyzed the volume strain data recorded from July 2007 to July 2008 in the Shandan in-situ stress monitoring station by using the statistical method, made a correlation of these seismic data with those recorded from other stations and studied the strain seismic waves, comseismic strain step and its contained physical significance, thus revealing the nature of the seismic strain waves.The data trends had pronounced anomalies.The effect of comseismic variation observed by the volume strain seismograph in the Shandan in-situ stress monitoring station was mainly the tensional step.
- Wenchuan earthquake,
- body strain,
- strain seismic waves,
- Chun-step with the strain,
- Earth's free oscillations,
- Chun-Ying capacity
