IF there is an earthquake...the ground starts shaking...
Do not get in a doorway. Do not run outside. DROP, COVER & HOLD ON...If you are outdoors, stay outdoors away from buildings. Trying to move during shaking puts you at risk: Earthquakes occur without any warning and may be so violent that you cannot run or crawl; you therefore will most likely be knocked to the ground where you happen to be. So it is best to drop before the earthquake drops you, and use your arms and hands to protect your head and neck. 不过下次肯定还有很多往外跑的 ---发自Huaren 官方 iOS APP
每次地震总有想往外跑的，连小学生都有地震演习和常识教育，普及一下： IF there is an earthquake...the ground starts shaking... Do not get in a doorway. Do not run outside.

一定要出去，待到天亮以后才安全。 ---发自Huaren 官方 iOS APP
不会好好说话就滚一边去
爱裸睡的人表示如果来了状况要裹着被子逃出去！
有的理论说小震频发把势能消耗掉，就不会有大震了，不知道靠不靠谱
号称要发生的七级地震，大概是今天这个能量的200倍.....
我咋记得不让跑啊，怕外面乱七八糟的飞来横祸
跑出去到空旷的地方呆着
小震不用跑，大震跑不了
.....
没感觉你怎么这么早就醒了？
earthquake.usgs.gov数据如下，自己算算多频发能抵消掉
https://earthquake.usgs.gov/learn/topics/mag-intensity/images/Mag-Energy-Freq-lg.gif
7级地震能量相当于1.8 Billion KG explosive，4级相当于56,000 KG explosive，能量差了上万倍
嗯。。。精确点说，7级地震能量是5级地震能量的1000倍
谁说白天不会地震？
1.8 billion / 1.8 million
差3个0

tech museum有地震模拟室，去体验一下八级九级啥感觉就心里有数了，想象和未知才是最令人恐慌的。 ---发自Huaren 官方 iOS APP
我本来已经准备睡了，地震后赶紧穿好衣服和老公在楼下等着，想着余震强烈就跑出去。 等啊等啊，等到困了也没来。
定义是每级差30倍左右，每两级1000倍。。。
好在加州的房子，尤其是民房都不高，比较抗震
IF there is an earthquake...the ground starts shaking...
Do not get in a doorway.
Do not run outside.
DROP, COVER & HOLD ON...If you are outdoors, stay outdoors away from buildings.
Trying to move during shaking puts you at risk: Earthquakes occur without any warning and may be so violent that you cannot run or crawl; you therefore will most likely be knocked to the ground where you happen to be.

对，我记得震级能量好像是指数级区分的。
原来你自己都是用马桶洗嘴，怪不得怪不得 ---发自Huaren 官方 iOS APP
好像是有的，2级的。
