西藏班戈县2006年4月20日的地震和灾情
|
摘要
文章阐述了西藏大学地震网利用意大利SARA公司生产的三项短波数字地震仪(SR97/S3),对2006年4月20日在西藏班戈县发生的里氏5.6级地震的观测结果和实地灾情调研的详细结果。并介绍了西藏班戈地带近年来发生的大地震的概况。实地考察发现,班戈县10个乡镇中的8个乡镇造成不同程度的影响;部分牧民住房被倒塌,部分新建房屋出现了裂痕;造成少量牲畜死亡,没有人员伤亡。
The paper reports the observation results of earthquake observed by the Seismic Network of Tibet University,with magnitude of 5.6 Richard scale occurred in Bangga County of Tibet on April 20,2006,and the detailed results of fieldwork investigation of the hazards.The paper also discusses briefly how the Seismic Network of Tibet University monitored the earthquake by using Italian SARA Company's three shortwave digital seismic instrument(SR97/S3),introduces the recent earthquake profile of Bangga region and eports detailed earthquake hazard situation obtained through the field investigation to the local residents.The spot inspection found that in Bangga County,8 of the 10 towns had suffered varying degrees of impact from the quake,some nomads' houses had been collapsed,and some new houses got cracks.The earthquake also caused a small number of livestock deaths,but there were no human casualties.According to the estimate made by the Earthquake Emergency Rescue Department of China Seismological Bureau,the earthquake hazards have caused direct economic losses of about 5.18 million Yuan.
