摘要
Rongchang area had exhibited low levels of natural seismicity. However, following the injection of unwanted water from gas production, seismicity has increased dramatically and showed progressive increase of magnitude. In order to make a thorough investigation on the injection-induced seismicity in the area, a temporal seismic network was installed in July, 2008 under the cooperation of the State Key Laboratory of Earthquake Dynamics, Geological Survey of Japan and Chongqing Earthquake Administration. The seismic network consists of 6 stations, by which waveforms are continuously recorded. As a result, both the detectability and location accuracy are improved greatly. This paper presents a brief summary of the cooperative project and some preliminary results of recent seismicity in the area.
