以下为USGS，United States Geological Survey 美国地质勘探局 的官方网页，其中对每天发生在全世界的4级以上及美国周边的2.5级以上地震都会记录，并且标示坐标、震级和深度，在这里看到的信息比国家地震局公布的要多，近几天的记录包括了国际地震局公布的所有地震，有的震级上有0.2级左右的差异，但时间地点是吻合的。如果自己有明显震感的，可以在几分钟后在此查阅。注意，时间请加上8小时才是北京时间。

大家可以看到这一天中国共发生了5级左右的强余震4次，20日凌晨的那一次也在列。同时，不难看出，我们地球可远远不像我们想象的太平。
当然，这只是个科学参考，没法验证其权威性也不能把它作为权威依据来进行决策。
请大家冷静、理智，这是对其他人最大的帮助，也是目前除了赈灾以外对祖国最大的支持。不要轻信谣言，不要在网上传播不可靠信息或者渲染紧急气氛。国难当头，匹夫有责！保持清醒，在当前就是爱国。
