ShakeAlert is a prototype earthquake early warning system for the West Coast. ShakeAlert for cellphones would warn users when ground shaking from a nearby earthquake will reach them, allowing time to duck and cover, as in this video dramatization.
ShakeAlert is currently being tested by some utilities, transportation systems and cities to shut down critical systems that could be damaged or cause injury during
violent shaking.

The japanese have a nationwide version this in almost every electronic pre installed.
yeah... everything since they open their system to manufacturer and you can easily get a permit to add the system to your own equipment while the US have restriction what you can place it in.
AGREED
:)
What is the app?
@@3oshcee its not an app its a program made by the japanese government
There is no need to use this app in Japan. If you don't have it, but you can notice earthquake alerts easily, because many people around you have it.

They look so calm with an magnitude 7 earthquake.
😮😮😮😮😮😮
earthquake will arrive in -3 seconds.
LMFAO
It's the seconds that has passed after the earthquake
earthquake will arrive in -8 seconds.
@@4ejl bro took 4 years to reply
Earthquake will occur in -7 years
In Japan and Mexico they have an alarm, that gives you one minute or more.
might be wise for the teacher to give her students a countdown so they can know when to expect the quake to hit
[someone from Mexico here].
In fact countdowns are not as easy or reliable as one would really think. This is because there are 3 main factors, the first is the origin/distance of the first sensors (since a good part of the arrival time depends on how far or near it has occurred)
The second is that not all earthquakes spread and move in the same way. and the third and most important are the delays in decoding and network saturation. [one of the reasons why, for example, the Mexican seismic alert system has plans but has not yet adopted the Cell Broadcast model and despite the existence of mobile Apps these are not reliable] and instead is based on the NOAA weather band and EBS radio and TV.
-so that, for example, in practice for Mexico City, the average warning time is 50 seconds; however, there are cases in which the time has reached almost 2 minutes or very short [20-30 seconds, in coastal areas it is sometimes only 10-15 seconds] or, for example, as in what happened in 2017, since it was an internal earthquake, there was no alert because it occurred much closer to the city than to the sensor area itself.
In turn, the type of soil affects a lot so that there are areas where it begins to be felt before others and in some cases the soil itself acts as an amplifier and is perceived or creates more damage than the rest.
[so a countdown could be more dangerous in terms of someone who could get more stressed, or trust because "they still have time"].
Here on youtube the community of fans of the system have several videos where we compare the performance of the system based on the monitor of the sensors (which shows a simulation of the waves and time of arrival) the response of the radios and the images or effects on TV (or in some cases at home)
-Other systems, like the Japanese, also do not show countdowns for the same reasons (and because in general, being a relatively small country, even in their videos you can notice that the times between the alert and the movement are minimal)

Teachers are trained to get their students to safety first.
That's so useful. I wish Australia, especially WA could have this warning on their cell phones.
We aren't near the tectonic plates so we're okay.
@@samuelvista Where do you live in? Why no earthquake warning apps?
@@magicanimal176production5 oh nvm, you said WA. I thought you meant the entirety of Australia.
but i thought australians didnt give a shit about quakes
Is there cell broadcast in Australia though?
I wish someone could make an open-source version of this app, so everyone could port it on everything.
ikr
We've had this app (an others) in Mexico for some years already, as part of a nationwide warning system that includes i.e. seismic sensors across the country, conected to a central warning centre, that in case of a large earthquake, triggers public alarms in all schools, hospitals and government buildings, and in an array of speakers on the streets. Also, we perform city-wide drills at least once a year, and each institution (either public or private) must have both safe zones and trained emergency coordinators in each floor of their buildings. So apps like this helps in case you are not at work or at the streets, and also give you an estimate of the time you have to leave the building / go to a safe zone within it. It´s not a perfect system, but buys you precious time, generally around 45 seconds and up to 1:30 mins, depending of the distance to the origin.
Is that the app screaming *ALERTA SISMICA* on repeat?
Yes, that's it @@ianhomerpura8937
@@ianhomerpura8937 It is possible you're describing the street speakers system!, usually the apps play out an alarm and also the expected magnitude and/or show on screen how much time its left before you feel it on your area [At least that's from the apps I have used/known]
Link this to the EAS so that earthquake alerts can trigger emergency alerts on TV and phone
The problem is that the EAS was designed to be set up in certain areas for the alerts. You can't just automatically send one out, you have to manually highlight/select what areas get the alert and then type out a message and then you got to send it, then the message has to decode BEFORE it can be broadcasted. By this point, earthquakes hits, and people are dead/injured. It can't be linked to the EAS because the EAS is terribly slow for this kind of thing. It's quick, sure, but it isn't THAT quick.
Wouldn't some kind of siren outside that the towns can hear be more noticeable? It could be automatically triggered like the phone is triggered.
Probably not. Sirens aren't loud enough to reach people who are indoors or doing noisy work. Something close and on your person is almost guaranteed to get your attention.
NORMAL THING IN JAPAN...
We need this apps!
震度３での通知？アメリカはそうなのか。日本では、このレベルで流れたら、一年間に１万回くらい聞くことになりそう
はい, 中国でも同じ ははは😂
Nevada has a Earthquake Alert System Warning App
App Calculated The Earthquake Magnitude Size
A Example before the Earthquake shakes
The fact it says TEST - Earthquake Detedcted! And then books fall, something breaks, *intense camera shaking* and- students not- uhhhhh- not, bouncing around the room.
Who will tell them the real position to do during a earthquake?
i like it that the app is as chill as the japanese eew
In China the prediction gives 10 to 180 seconds, depending how far u are from the epicenter
Awesome. Pray it works 🙏
0:59 Fun fact: the items did not get hurt
But not the dishes.
Strong shaking expected
Τthis video has an error. The teacher and the children must hold the leg of the table to be fully covered. Anyway, well done for the effort
Excellent - great work!
donde puedo adquirir esa app o ese servicio para que me notifique unos segundos antes??????? alguien me puede decir porfavor
Why in the F don't we have this yet. Japan, Mexico, Romania, and Turkey all have it. Turkey and Romania! Japan has had it for 11 years!
Joe Diver The sad part is that we've had the funds for almost a decade to give all Californians access, but every few months, USGS says that they don't have enough money or that it's still "being tested". It's been proven over and over to properly and accurately work, so I want to know the real reason! I've been told by a neighbor who works for USGS that the "higher ups" don't want us to have it because it would "scare" the public.
Mexico for more time
Joe Diver Actually in turkey we dont
Seismic waves in -what- seconds.
most calm kindergarten class
At least earthquakes aren’t scary I remember I been in a earthquake at South Korea and all I did before the earthquake arrived I went to a field with no trees and standed outside until it was over I was ok it only lasted 6 seconds
This is completely irrelevant, but am I the only one who thinks those tables wouldn't really help?
Most of the injuries from earthquakes in properly constructed buildings is from flying objects, like glass, bookcases, etc.
That's the same thing I thought
bmo That's not true. Most injuries come from people trying to run or walk to safer areas during the quakes.
Earthquake sounds like rocket
If a 9.9 Earthquake hit the whole earth:
Singers : OH CLAMMY BOY, THE EARTH THE EARTH IS GETTING DESTROYED, FROM EVERY COUNTRY
Actors : oh god
Ragers: (rages so hard)
Me : good bye earth
People : AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
It's working in Turkey?
The shake alert turn on in the middle of a 5.3 quake on my phone.
It's gonna be super careful on the eartyou need to be safe
is earthquake at the San frisco and San jose

Earthquake Duck cover and hold on
China and Japan already have a system like this
i think south korean should get that system incase of earthquake though.
I don’t need this app because I live in Estonia and there are no strong earthquakes. People don’t even notice the earthquake in our country.
1:32 reminds me of the song I got friends from the other side from Princess and frog.
Oh yea I have the app and it did alert me of a quake but I didn’t feel it
Check it barkeley
Is there any apps for it because I don’t see any😢😢😢😢😢😢
Modern android Phones have it built in now
If Maldives Had This During The 2004 Tsunami This It Better
I don't know about that
Oh...
Very cool.
I love New Hampshire
That's a very edgy announcer

I Remember Have A Earthquake At School In The Year 1978 When I Was Born In The Year 1972 I Was In 2nd Grade At The Time I Was In Math My Teacher Was Miss Blackburn She Is Nice But Strict My Name Is Lily Curtis
Lilly Curtis Gaming yeah that’s hard to believe
damn bro, but I really gotta wonder
who asked
@@greyfiveys I see that username, what rank?
@@NoTraceOfSense I'm decaying rn but last time I checked 830k
Legit shaking
This kills me lol
ん?なんか思ってたより揺れてなくね?
OH SH A EARTHQUAKE
Wait bro lemme record pause the earthquake
This is the most realistic stuff I ever seen😂😂😂
1cm Tsunami from a Greek I’m so scared>-
Sounds
This is a moment to tell all people around world that now there is an earthquake alarm for the first time in human history that can predict earthquake minutes before it happen.so this is a moment.i predict that there will be an earthquake in java indonesia that have longitude around 106 east till 108 east.it will have magnitudo 4 till 5.9 wity maximum depth 80 km or magnitudo 6 till 10 with no limits of depth.it will happen in 30 march 2023 and time around 0.00 utc time
........around 23.00 till 01.00 utc time
So if this come true it will a big step for human kind that we can predict an earthquake for first time in history.youll be a part of history to see this happen.see you in 30 march 2023....check it barkeley usa....youll find amazing moment of history....bye see you again...
If it gave
Android (samsung) is the king of smartphones .
I hate earthquake to distory my home and knock stuff down
An earthquake there can you make the table now rhr chera what is a shake america
dis alarm: Nothing
Filiny. Clean chat area
Idh :(
My god barkeley its all done in java....bye bye berkeley
Only me can predict an earthquake so accurate
Lol
Me par
thats on china
you think everything is from china💀💀
@@Aviatorgorilla no but in Chinese device they have that kind (very different)
@@BodoqueBG ohh
Eas siren head
as a romanian the earthquake is very unrealistic also that countdown wont be that accurate
Japans EEW is pretty accurate and on time wdym?
