IASPEI 2009: Rhythm of the Earth (Cape Town, South Africa)


On behalf of IASPEI Bureau, I would like to thank all of you for your participation in this memorable Assembly ĘC I know that some of you are from very remote places, most of you are from another hemisphere. Especially, we would like to extend our thanks to our African colleagues - we hope and believe that seismology in Africa will have more and more contributions not only to regional sustainability but also to global geo-science.

Response Changes of Wells in the Mainland Subsurface Fluid Monitoring Network of China, Due to the Chi-Chi Earthquake
                        - Fuqiong HUANG et. al.

Feature article About 60 hydrologic changes in response to the Chi-Chi earthquake with Ms7.6 on September 21, 1999, occurred in 52 wells, including groundwater level, temperature, discharge rate, well pressure and radon, etc., in the subsurface fluid monitoring network. These response changes were mainly co-seismic, but some pre- and post-earthquake changes occurred mainly within 5 days before and after the Chi-Chi earthquake. The response changes of different wells clustering in different tectonic areas showed different features.
