Earthquake Alerts follows earthquakes worldwide through five independent agencies at once, and shows you which information came from where. AN INDEPENDENT APP This is an independent app published by BUSATER YAZILIM A.Ş. It does not represent any government agency and is not affiliated with the agencies named below; it shows the measurements they publish openly, each with its source. WHAT MAKES IT DIFFERENT Most apps show one agency's data. This one collects the same earthquake from USGS, EMSC, GEOFON, GeoNet and INGV, merges them into a single event, and puts their differing measurements side by side. You see which value is displayed and why that agency was chosen. IT DOES NOT HIDE REVISIONS Agencies publish an automatic solution within minutes, then correct it after analyst review. This app does not quietly swap the number: if a magnitude moved from 5.8 to 6.1, if the depth changed, or if the solution was reviewed, you see the full history. WHY YOU RECEIVED THIS ALERT Every notification explains itself — which of your rules matched, what your threshold was, and how far away the earthquake was measured. Alerts that were not sent are listed too, with the reason. LOCATION-BASED ALERTS Create separate rules for home, work, or where your family lives, each with its own radius and minimum magnitude. A PROPER MAP Satellite imagery, clustering, tectonic plate boundaries, and markers you can read at a glance. Filter by exact thresholds such as M4.5 and above. BEING HONEST Earthquake Alerts is not an earthquake prediction service. It shows measurements published by official agencies for earthquakes that have already happened, and does not replace official early warning systems.
