Overview

• The system now covers 98 countries and territories with over 2.3 billion Android devices opted in by default.
• From 2021 through 2024 the network detected an average of 312 earthquakes per month and captured more than 11,000 tremors worldwide.
• Alerts for quakes of magnitude 4.5 and above average 60 events and 18 million notifications each month.
• Only three false alarms were recorded in 1,279 events as of March 2024, prompting targeted algorithm updates to reduce spurious triggers.
• Android-based detection complements conventional networks like ShakeAlert by identifying P and S waves and categorizing alerts as “Be Aware” or “Take Action.”
