| Abstract: | A multi functional high frequency seismometer, a new instrumental system, is used for recording multi point strain variations of rock samples in the process of fracture development. The results indicate that strain in each point appears burst disturbance synchronously besides a tendency variation before main fracture. The burst disturbance could probably be one of the short impending precursors before great earthquake. |
