Introduction to the China earthquake measuring at June 17: at 2:17 on June 2 May 2009 55 points, Sichuan Yibin County Mayor 6 earthquake occurred, focal depth of 16 km. Disaster Mitigation Institute of Chengdu Hi-tech way through radio broadcasts, SMS, TV and so on, 61 seconds advance warning sent to Chengdu, 31 seconds ahead of early warning to Bijie City, Guizhou Province, issued a warning to 10 seconds ahead of Yibin City.
The following are two days in the online crazy pass short video. I have not seen that we can look at. In addition to broadcasting the following warning, disaster mitigation by the Chengdu Hi-tech Research Institute developed the earthquake early warning APP also played a significant role.

What is an earthquake early warning
Earthquake early warning technology is a networking technology system-second response. By laying intensive earthquake early warning monitor in a major earthquake zone, and when the earthquake epicenter determined, using the wave propagation speed is faster than the seismic wave principle, early warning alarm in advance.
Earthquake early warning is not earthquake prediction, by the waves beat the seismic waves.
In the disaster comes, even if only a few seconds of warning time, also allows people to make timely hedging measures to reduce losses and casualties.
If you happen to not watching TV, listening to the radio, did not hear the warning horn public broadcasting, then download the "earthquake early warning" developed by the Institute of Disaster Mitigation in Chengdu High-tech in the phone app, you can also obtain earthquake warning service in a timely manner.
How to use the earthquake early warning APP
The software currently supports both Android and iOS. Also yesterday, this APP in iOS applications market has suddenly fire. Direct download iOS soared top of the charts. As of this afternoon, when I see, also ranked in the top two. (This can Jingdong financial APP ranked first since 618)
1, first download and install the "earthquake early warning" APP this software. You can apply directly to the market in iOS and Android application market search download. Note that you should not download the wrong (look for the icon in the figure)
2, ensure that the application of the "boot" and "background" privileges. Download and install "earthquake early warning", the need to open the "boot" permission for earthquake early warning software, as well as "background" permissions, and allows software notifications in the notification bar to display smooth, and maintaining the network. This step can be avoided app is set to kill background of your phone.
3, set the software "warning Strategy"
In the software "is set - Early Warning Strategy", we can set the threshold magnitude and intensity thresholds during the day and night.
当发生的地震及其所造成的影响大于等于设置阈值时，预警软件会弹出窗口，并发出倒计时警报。在不同的地震程度下，报警声有不同的样式。
当发生的地震及其所造成的影响小于设置阈值时，预警信息存在预警记录内，不发出声音警报。
成都高新减灾研究所给出的触发策略建议是：白天为 4 级 2 度，夜晚为 5 级 3 度，大震提醒的触发震级可选择 6 级。
用户可以在应用上可以从震感、房屋破坏、人员死亡、交通破坏、其他灾害、险情上报这六个维度，进行灾情报告。
▌ 最后
在这个 app 里，还有地震预警避险策略的相关科普，不管有没有发生过地震。以防万一。
