来自新华网的消息：在今天凌晨1:52发生了一次较强余震，然后，四川日报的记者在2时左右采访了相关地震专家。该专家称，“发布的紧急通知是根据中国地震局《关于汶川8.0级地震近期余震趋势意见的报告》作出的。” 专家谈发布余震预告 根据近期余震趋势作出。 那么如何采取避震措施呢？ 省地震局研究员韩渭宾介绍：对于这次公告预测的强余震，位于余震区及其边缘的居民当然要采取必要的有效避震措施，因为那里的多数房子倒塌或者遭受严重破坏，即使没有倒塌或严重破坏的房子，也已被震松，现在又面临可能发生的强余震，不能居住，必须搬出来。对于成都市区而言，与汶川直线距离约90公里，离龙门山断裂带最近距离也有50公里，在余震区即使发生6—7级强余震，也不会造成明显破坏。实际上，汶川8.0级地震在成都也仅仅是强烈有感，个别房屋的抹灰层有掉灰和细小裂缝。震级小一级，能量大约小30倍，因此，只有个别危房不能住，需要到开阔地方避震，多数经受8.0级地震考验依然完好的建筑物不会有危险的。至于更远地区，危险性更小，更不必恐慌。（from 专家谈发布余震预告 根据近期余震趋势作出） Send article as PDF
