　　央广网恩施12月17日消息(记者张晶) 据中国之声《央广新闻》报道，昨天中午，湖北省恩施土家族苗族自治州巴东县发生5.1级地震。

　　湖北省地震局分析了昨天下午13点4分52秒发生在湖北恩施巴东县的5.1级地震的原因，初步判断是矿山和溶洞诱发。

　　据湖北省地震局副局长刑灿飞介绍，地震发生地是恩施溶洞的地质构造带，多煤矿石膏矿等矿产。

　　初步判断地震发生是开矿导致水位提高以及溶洞塌陷诱发地震，具体原因还需要进一步的调查。

　　另外，从地震局的消息说，当地最近仍然可能发生一些小型的余震，但是该区域不具备发生较大地震的条件。由于当地特殊的地形和地质环境，近期需要谨防滑坡、滚石和泥石流等次生灾害。

　　记者刚刚从恩施州人民政府得到最新的关于受灾情况的汇总消息。昨天下午的13时的4分52秒，巴东县发生了5.1级的地震，震源深度是5千米，随后发生了2.3级和2.2级的余震，截止到昨天晚上的8点，地震灾情是涉及到巴东全县12个乡镇的208个村，21000多人受灾，其中有3个人受伤，其中伤人中有两个人已经送往医院救治，没有人员死亡的情况。
