Earthquake (ALERT) is a free Chrome extension designed to monitor earthquake activity by parsing data from the US Geological Survey (USGS) API. Users can set customizable alerts based on earthquake magnitude, receive notifications about the status of reported data, and track changes over specified time ranges. The extension aims to enhance user awareness of significant earthquakes through audiovisual alerts, making it a valuable tool for those interested in seismic activity.

The program operates exclusively on the USGS earthquake map page and does not collect personal data from users. It displays the status of earthquakes using a color-coded system to signify whether the event has been reviewed, is automatic, or has other classifications. The extension is open-source and designed to run efficiently, though it may consume more RAM compared to similar extensions. Users can find additional information and source code on the developer's GitHub page.
