乌鲁木齐遥测地震台网的速报定位
|
摘要
分析讨论了乌鲁木齐遥测地震台网在1993年9月～1995年12月31日期间速报的216次地震。认为乌鲁木齐遥测地震台网，对发生在乌鲁木齐地区的地震，在10分钟内可给出定位结果，定位精度达Ⅰ类；对发生在北疆地区的地震，在震后20分钟内可给出定位结果，定位精度达Ⅱ、Ⅲ类；对南疆发生的地震，需用人工地震台站的资料进行交切定位。发生在国内（除新疆）和国外的地震，除墨西哥以南发生的地震定位效果不太理想外，其余地区的地震，用乌鲁木齐遥测地震台网资料进行定位，结果达到规定要求。
The 216 earthquakes rapidly reported by Urumqi Telemetry Seism Network from Sept. 1993 to Dec. 31, 1995 are analysed in this paper. It is thought that the network can locate an earthquake in Urumqi in 10 minutes, and its location accuracy up to type Ⅰ; for a earthquake to occur in North Xinjiang it can give results in 20 minutes, and the accuracy up to type Ⅱ or Ⅲ; but for the earthquakes in South Xinjiang, it needs to use the data from artificial seismic stations to intersect and locate. In addition, the results that Urumqi Telemetry Seism Network locates home (excluding Xinjiang) and foreign (except the area on the south of Mexico) earthquakes are also able to meet the demand.
