兰陵2.9级地震源自停产多年石膏矿采空区塌陷,无人员伤亡

国家地震台网官方微博消息,中国地震台网正式测定:12月28日21时8分在山东临沂市兰陵县(北纬34.78度,东经118.09度)发生2.9级地震(塌陷),震源深度0千米。

记者从中共兰陵县委宣传部获悉,2019年12月28日21时08分,兰陵县兰陵镇远发石膏矿采空区发生塌陷,塌陷面积约5亩,无人员伤亡。该矿2015年12月25日停工停产,2018年4月经临沂市安委会批准,进行人工强制放顶试点,此次塌陷属人工强制放顶区后续自然塌陷。

目前,该矿采空区地上无人员居住,无地上附着物。下一步,当地将继续采取物理隔离,加强监控,跟进后续治理。
