No, "Google" did not do it; the ShakeAlert program [0] and their research partners [1] (USGS, CalOES, Cal Geological Survey, CalTech, UC Berkeley Seismological Lab, UW, UOregon, ETH Zurich (SED), Gordon and Betty Moore Foundation). Seems like they're doing an A+ job on the technical work and a D job on self-promotion :) , it's impossible to find a single webpage listing the ShakeAlert project's team, current and former. But they deserve due recognition and praise. As to @datadata's comment, "Earthquake Early Warning system" doesn't mean "predictive seismology", it means a (crowdsourced syndicated sensor-based) early warning of maybe 1-10 seconds, on the surface, P waves travel at 3.7 miles/s [2]. Even a 10-second early warning is enough to signal transit, turn off pipelines, put up early warning signs on freeway and in transit, send textphone alerts, avoid disasters, save lives, etc. This was one of the lessons learned from 1989. This project is a success story and deserves to be written about more. I'd also be interested also to read about the level of interoperability with earthquake and tsunami early warning systems in Japan, SE Asia, ME etc. An alarming counterstory was the 2018 Indonesia tsunami early detection buoys (off Sulawesi) haven't worked for six years due to 'lack of funding' @alvarezbjm-hn: I helped organize a talk by one of the UCB SeismoLab researchers, she specifically addressed the privacy concerns people occasionally ask about ShakeAlert not retaining PII or being useable for tracking individuals. As to Android itself, that's a different story. (But if you wanted an app to track people intrusively, an app that doesn't use PII and is from a US-taxpayer funded program with federal and state oversight is probably like the last target you'd pick...) (As to ascribing everything that happens on an Android phone to "Google", if the phone market/OS majority was Xiaomi or Huawei or HarmonyOS, the result would be the same. Google did not make the phone hardware or its MEMS accelerometer) [0]: https://www.shakealert.org/ https://www.shakealert.org/ [1]: "ShakeAlert—An earthquake early warning system for the United States west coast, USGS Fact Sheet 2014-3083" https://pubs.er.usgs.gov/publication/fs20143083 https://pubs.er.usgs.gov/publication/fs20143083 [2]: https://www.britannica.com/science/seismic-wave https://www.britannica.com/science/seismic-wave
