摘要
利用宽频带数字地震仪在川西高原、云贵高原西部开展了为期一年的地震观测,记录了许多地震波形数据,并对川青地块、川滇地块和华南地块上的5个台站的不同地震纪录进行了频谱试分析。
The seismic observations were made for the eastern Qinghai-Xizang Plateau and its adjacent areas by using PASSCAL broad digital seismometers during the period from October 2003 to October 2004. The tentative analysis of frequency spectra was finished for the seismic records from five stations installed within the Sichuan-Qinghai, Sichuan- Yunnan and South China blocks, respectively.
