西藏是我国地震多发地区,地震具有频度高、强度大、分布广的特点。西藏地处横贯亚洲地震带的强震带上,地震活动仅次于我国台湾省。据1900年以来的资料统计,全区共发生6.0级以上地震113次。1950年8月15日察隅8.6级地震,1951年11月18日当雄发生的8.0级地震是本世纪我国发生的最强烈的地震。 在党中央的关怀下,1956年中国科学院地球物理研究所在西藏拉萨建立了“拉萨地球物理观象台”开展地震、地磁观测。1975年6月经西藏自治区党委同意成立“西藏自
Tibet is an area with many earthquakes in our country. The earthquake has the characteristics of high frequency, great intensity and wide distribution. Tibet is located on a strong earthquake belt that traverses the Asian seismic belt and is second only to Taiwan Province in China. According to statistics since 1900, a total of 113 earthquakes of magnitude 6.0 or above occurred in the region. The 8.6-magnitude earthquake of August 18, 1950, the 8.0-magnitude earthquake that struck the island of Dangxiong on November 18, 1951, was the strongest earthquake in our country this century. Under the care of the Central Party Committee, in 1956, the Institute of Geophysics, Chinese Academy of Sciences established the Lhasa Geophysical Observatory in Lhasa, Tibet to carry out the earthquakes and geomagnetic observations. June 1975 By the Tibet Autonomous Region Party committee agreed to set up "Tibet since
