ManyLos Angeles residents thought the ShakeAlertLA app on their phones should havegiven warning. Officials said the system had worked as designed — butpromised some changes.

許多洛杉磯居民認為,他們手機上的ShakeAlertLA應用程序應該發(fā)出警告。官員們表示,該系統(tǒng)已在按設計運行,但也承諾會做出一些改變。

LosAngeles residents were not pleased last week when a pair of earthquakes struckand the ShakeAlertLA app on their phones did just what it was supposed to do:nothing.

上周,當兩場地震發(fā)生時,洛杉磯居民感到并不開森,他們手機上的ShakeAlertLA 應用程序沒有任何反應。

The app, releasedto the public on New Year’s Eve after more than a year ofdevelopment, is intended to give at least a few precious seconds of noticebefore dangerous shaking from an earthquake. But users didn’t get thenotifications they expected on Thursday and Friday when two powerfulearthquakes struck in the Mojave Desert, and many people assumed that the apphad failed

經(jīng)過一年多的開發(fā),這款應用程序在除夕夜向公眾發(fā)布,其目的是在地震造成危險晃動之前,至少提前幾秒鐘發(fā)出寶貴的通知。但周四和周五莫哈韋沙漠發(fā)生兩場強烈地震時,用戶沒有收到預期的通知,很多人認為這款應用程序已經(jīng)失敗。



So, though Dodger Stadium quivered and LosAngeles movie theaters were evacuated because of the tremors,the quakes’ effects did not exceed the system’s minimum threshold in LosAngeles County, the only place where the ShakeAlertLA app has been implemented.

因此,盡管Dodger體育場發(fā)生了震動,洛杉磯的電影院也因地震而疏散,但地震的影響并沒有超過洛杉磯的最低閾值。洛杉磯是唯一一個實施了ShakeAlertLA應用的地方。

The system is intended to notice an earthquake of 5.0magnitude or greater, and then predict where in the county the quake is likelyto be felt at an intensity of 4 or more. Alerts are sent to users in thoseareas.
At thatintensity, which is measured on a different scale thanmagnitude, cars will rock, dishes will rattle and people will feel theearthquake indoors — and may even be roused from sleep.

該系統(tǒng)旨在發(fā)現(xiàn)5.0級或以上的地震,然后預測該縣哪里可能感受到4級或4級以上的地震。警報將發(fā)送到這些區(qū)域的用戶。
在這種強度下,汽車會晃動,盤子會嘎嘎作響,人們會在室內(nèi)感受到地震——甚至可能從睡夢中驚醒。

The system did notissue alerts because, immediately after the quakes struck, it predicted thatthey would not exceed the intensity threshold anywhere in the county. As itturned out, parts of western Los Angeles felt the second quake more stronglythan predicted — an intensity reading of 4.5 was recorded in one area ofwestern Los Angeles — and downtown just missed the threshold at 3.9. Butthat was not known until after the fact.

地震發(fā)生后,該系統(tǒng)沒有發(fā)出警報,因為它預測,地震強度不會超過閾值。
事實證明,洛杉磯西部部分地區(qū)感受到的第二次地震比預測的更強烈——洛杉磯西部一個地區(qū)的強度為4.5級,而市中心剛剛錯過3.9級的臨界值。但那是事后才知道的。



What are users saying?
Still, someusers of the app were surprised and disappointed to hear that the system wasworking as intended when it issued no alert last week.

用戶的看法?
盡管如此,當該應用程序上周沒有發(fā)出任何警告時,一些用戶聽到系統(tǒng)按預期運行會感到驚訝和失望。

“So the app did nothing during today’s quake and therefore‘performed as designed,’” a Twitter user named Kyle Krupinski wrote. “Seemslike a pretty low bar to achieve.”

一位名叫Kyle Krupinski 的推特用戶寫道:“所以這款應用在今天的地震中什么也沒做,因此‘表現(xiàn)得像設計的一樣’?!薄斑@似乎是一個相當?shù)偷哪繕恕!?br/>
Some peoplesuggested that the app be programmed to provide two kinds of alerts — onefor relatively minor tremors and another for more serious earthquakes — orthat users be allowed to set their own thresholds.

一些人建議,這款APP應該被編程為提供兩種警報——一種針對相對較小的震動,另一種針對更嚴重的地震——或者允許用戶設置自己的閾值。

AnotherTwitter user, Sergio Treviño, tagged Mayor Eric Garcetti of Los Angeles andsaid he was “waiting for today’s excuse.”

另一位推特用戶SergioTrevino給洛杉磯市長Eric Garcetti貼上了標簽,說他“正在等待今天的借口”。

————推特評論(無ID)————

As if theground shaking wasn't enough?

說得好像當時的地震不夠強似的。
啊,我愛科技。



Lol that’s California in anutshell

哈哈,簡單說這就是加州了。/笑哭

Stop talking about Los Angelesresidents 200 miles away, how about the San Bernardino residents at epicenter.Same people that called the RESEDA earthquake, the Northridge Earthquake. Awfulgeographic bias.

不要再談論200英里外的洛杉磯居民了,震中的圣貝納迪諾居民呢?與人們所說的里塞達地震,北嶺地震一樣的震級了。真是可怕的地域偏見。

Next time? That’s helpful

下次?是挺有幫助的。/不高興

Maybe itwasn't the app.?

也許那不是APP。

Lmao andpeople are concerned about AI takeovers...please.

啊哈哈哈哈,就這樣人們還擔心AI統(tǒng)治世界呢,得了吧
