1982年10月8日乌鲁木齐市西南郊发生Ms=4.1级地震,之后,余震频繁发生,1.0级以上地震都有感。尽管4.1级地震震级不高,但由于一近(离市中心约10公里)二浅(震源深度约10公里),小余震均有感,因而造成相当大的社会影响面。对此,我们通过密切监视震情,落实异常,综合判断,果断地向社会公开发布了“乌鲁木齐地区短期内发生大震的可能性不大”的预报意见,配合正面宣传,取得了良好的社会效果。 After Ms = 4.1 earthquake occurred on the southwestern suburbs of Urumqi on October 8, 1982, aftershocks frequently occurred and earthquakes above 1.0 were felt. Although the magnitude of the M 4.1 earthquake is not high, the small aftershocks are felt due to the proximity (about 10 km from the city center) and the shallow depth (focal depth of about 10 km), resulting in a considerable social impact. In response, we closely monitor the earthquake situation, implement the anomaly and make a comprehensive judgment. We resolutely released the forecast opinions to the public that “the possibility of a large earthquake in the near future will not be large in Urumqi region.” In the light of positive publicity, we achieved a good social effect.
