Alerta de Sismo

Alerta de Sismo is an essential Chrome extension from the Ministry of Environment of El Salvador (MARN) that provides early warnings for nearby earthquakes. It alerts users when seismic activity is detected within 50 to 150 km, giving crucial seconds to take protective actions. The extension categorizes alerts into Red (severe shaking), Orange (moderate shaking), and Green (minor shaking), with distinct notification methods like voice commands, sound, vibration, or silent alerts.

This fully automated system integrates multiple instruments and algorithms to detect and notify about earthquakes effectively. The extension is free and enhances public safety by enabling users to report their earthquake experiences, creating a connected community informed by real-time seismic data.
