青海东北部地区地震直达波波速比及视速度测定与研究
Determination and study of wave velocity ratio and apparent velocity in the northeast of Qinghai Province
摘要
Abstract
Using the observation report of Qinghai Digital Seismic Network and multi-station method, the wave velocity ratio and apparent velocity of the earthquake in the northeast region of Qinghai Province during Jan., 2009 to Dec., 2014 are determined The study shows:①In the 5 subregions, the average velocity ratio values are in a range of 1.685—1.705. The average P wave apparent velocity values are in a range of 5.979—6.022 km/s; the average S wave apparent velocity values are in a range of 3.535—3.579 km/s.②The complex characteristics of velocity ratio and apparent velocity in the study area reflect the complexity of crustal medium and geological structure, but it may also relfect the inlfuence on the result of different seismic ray path.关键词
