- Abstract:

We conduct a comparative analysis of volumetric strain response of extensometer and the volumetric strain response of body-strain gauge to the same earthquake.The two observational systems recorded an oscillating attenuation change overlaying the background of the solid tide of volumetric strain.The two systems differently response to Indonesian distant shock,inland earthquake and Taiwan earthquake.The magnitude of volumetric strain response of these two systems to the earthquakes varies from 10-9 to 10-7.The response amplitude of body strain gauge system is larger than that of extensometer.For the same system,the response amplitude keeps in direct proportion to quake energy and the delay time of response keeps in direct proportion to epicentral distance.
