2023年土耳其发生大地震后，Google承认其Android地震预警系统（AEA）在此次灾难中未能有效发挥作用。该系统仅向少数用户发出了最高级别的“采取行动”预警，而本应覆盖数百万受影响人群的警报却未能及时送达。尽管Android手机具备充当“迷你地震仪”的潜力，且土耳其Android用户比例很高，但预警系统的失灵导致许多人在睡梦中未能获得关键的避险时间。Google事后解释称，预警系统的局限性在于检测算法未能准确识别地震的震级，而模拟测试显示，使用改进算法可生成数千万级别的预警信息。

⚠️ Google的Android地震预警系统（AEA）在2023年土耳其大地震中表现不佳，仅发出469次最高级别的“采取行动”预警，本有机会向98英里范围内的1000万人提供关键的避险时间。

📉 该系统本应为用户提供最高级别的“采取行动”警报，该警报会覆盖“勿扰模式”并发出声音提示，但实际发出数量远低于预期，而较低级别的“注意”警报虽然发出量较大，但效果有限。

📱 Android手机通过充当“迷你地震仪”来检测震动并将其信息传达给Google服务器，鉴于土耳其超过70%的用户使用Android系统，该预警系统本应具有广泛的覆盖能力。

🗣️ 许多土耳其居民在地震发生后表示未收到任何预警，而Google起初坚称系统有效，但近期发布的科学论文指出，算法限制导致系统未能准确检测地震震级，改进算法的模拟测试表明可生成大量有效的预警信息。

Google has admitted its earthquake alert system largely failed during the 2023 earthquake in Turkey.

The tech giant told the BBC that its Android Earthquake Alert (AEA) feature only sent 469 "Take Action" warnings for the deadly 7.8 magnitude earthquake. If working the way it was supposed to, the alert system reportedly could have given 10 million people within 98 miles of the earthquake's epicenter critical seconds to find safety.

The "Take Action" alert is the feature's highest warning and overrides user's Do Not Disturb setting with a full-screen notification and audible warning sounds. Google told the BBC that it sent half a million people the lower level "Be Aware" warning that is meant to indicate lighter shaking and does not override the Do Not Disturb setting. The first earthquake began a little after 4 o'clock in the morning, when many people were asleep. The death toll was over 55,000, with the earthquake killing people in Eastern Turkey and parts of Syria.

Google's earthquake alert system works by using Android phones to work as "mini-seismometers" to detect vibrations and communicate that information to Google's earthquake detection servers, according the feature's page. Over 70 percent of phones in Turkey use the Android operating system, so this alert could have had wide reach.

Back in 2023 when the earthquake hit, the BBC spoke to hundreds of Turkish residents and "didn't find anyone who had received a warning." At the time, Google insisted to the outlet that the alert system had worked. Google cited "limitations to the detection algorithms" that failed to detect the magnitude of the earthquake in a paper recently published in Science. According to the paper, researchers simulated the Turkey earthquake with an improved algorithm and reported that the system generated 10 million Take Action alerts and 67 million Be Aware alerts.
