> Another thing Google has had for some time is early Earthquake warning....maybe that's another feature you'll see show up on iPhones in a few years, and people like you will claim Apple invented it and praise Apple for it.
iOS has supported early earthquake warnings in Japan since iOS5. (see https://9to5mac.com/2011/08/21/ios-5-includes-early-earthqua...)
For other regions, like California, you can download a supported app to receive alerts, like MyShake (https://myshake.berkeley.edu).
