#QQ微信上线地震预警功能#
rushed to the hot search on Weibo
Tencent responded on Weibo
It was a feature that was quietly launched the night before
Last year, Tencent and the Sichuan Provincial Earthquake Bureau jointly launched the "Sichuan Earthquake Early Warning Platform WeChat Mini Program". On May 12, the applet was upgraded and optimized - it supports setting multiple places of interest, adding earthquake quick reminders, and adding a multi-location alarm information aggregation page. At the same time, the QQ platform has also officially launched the earthquake early warning function. This also means that Tencent's dual-platform earthquake early warning covers the whole province of Sichuan.
Now, Sichuan has achieved it
Earthquake of magnitude 5 or higher in the province
5-15 seconds after the earthquake
The ability to issue early warnings of earthquakes
Earthquake early warning services in other provinces will be launched soon
How do I turn on an earthquake warning?
Follow the steps below
↓↓↓
WeChat platform
Search for the "Sichuan Earthquake Observatory" official account on WeChat, follow the official account to turn on the earthquake warning, open the applet to set the warning location - click to agree to privacy protection - click to turn on the earthquake warning - click to allow the warning notification - click to allow location authorization.
QQ platform
Search and follow "QQ City Help" - click "Earthquake Warning" - click to add warning location - select the intensity range.
Yesterday at about 4 o'clock in the morning
Muli County, Liangshan Prefecture, Sichuan
A magnitude 3.7 earthquake occurred
WeChat success warning
"Sichuan Earthquake Station" applet
The page displays the real-time location
and recent earthquake information
Warning position
Multiple points can be set
After saving the settings, you can experience the earthquake early warning simulation demonstration, which displays the arrival time of seismic waves, predicts the intensity, magnitude, distance from the epicenter, and other information.
Is earthquake early warning useful? Fast?
Here comes the answers to these questions you care about
↓↓↓
ask
What is an earthquake warning?
Earthquake warnings are in the fight against the time difference. When an earthquake occurs, longitudinal waves and transverse waves will be generated, and the longitudinal waves are fast and destructive; Whereas, transverse waves have a slow speed and high destructive power.
When the seismic station captures the longitudinal wave signal, it will transmit the epicenter location, magnitude and other information to the early warning terminal through faster electromagnetic waves, so that it can gain emergency evacuation time for the surrounding cities in a few seconds to tens of seconds before the transverse wave arrives.
ask
Is early warning useful?
Useful! Studies have shown that a 3-second advance warning can reduce casualties by 14% and 20 seconds by 63% (Source: Northwest Seismological Journal 2002).
In just a few seconds to tens of seconds, chemical plants and nuclear power plants can urgently close solenoid valves or shut down reactors, running high-speed trains and trains can be braked urgently, low-floor residents can be evacuated to the outside of the building, and high-floor residents can take refuge next to solid objects.
ask
Is WeChat and QQ push fast?
The biggest demand for earthquake early warning is fast. The Sichuan Provincial Earthquake Observatory has been connected to the official authoritative early warning data of the China Earthquake Early Warning Network, WeChat has set up an independent message channel that can be flexibly expanded for the earthquake early warning, and QQ has mature technical reserves for the high-concurrency message push of a large number of users.
ask
Are there any plans to go live in more places?
Yes! Hold your horses. Under the guidance of the China Earthquake Administration, Tencent is developing a national WeChat earthquake early warning service platform, which has entered the internal testing stage and will soon be launched nationwide. QQ's city-wide earthquake early warning function will gradually cover more provinces.
Netizen comments: This is practical!
Looking forward to this
A life-saving feature at critical moments
Promote the whole country as soon as possible
Again, that's the same sentence
I hope you don't need this feature
