# Seismology: Earthquake Alerts

> Taken from the public Google Play listing. Every figure below carries the date it was updated.
> Nothing is modelled or estimated. A new collection starts at 00:00 UTC daily and takes several hours; an individual app's reading lands at some point inside that window.
