Passive triaxial sensors mounted on foundational structures detect motion in multiple axes, ensuring accuracy across different ground compositions.
How It Works
How ShakeAlarm® Delivers Seconds That Matter
From First Vibration to Final Action — Instantly
Detection
Installed seismic sensors (triaxial accelerometers or geophones) continuously monitor for P-waves—the fastest seismic waves that precede destructive shaking.
Analysis
Real-time data is transmitted to ShakeAlarm®’s local processing unit or ShakeAlert® network integration, which verifies the seismic event and distinguishes between harmless vibrations and real threats.
Decision
If the signal crosses predefined intensity thresholds, ShakeAlarm® issues a ‘Shake’ or ‘No-Shake’ command within milliseconds.
Response Activation
Emergency protocols are activated automatically—this may include system-wide alerts, gas/electric shutoffs, elevator return to ground level, train halts, and more.
Precision-Engineered for Instantaneous Safety
Data Acquisition Units
Convert analog seismic inputs into digital data and transmit them in real-time to the analysis system.
Analysis Engine
High-speed industrial processors equipped with Shake/No-Shake logic powered by proven P-wave detection algorithms.
Response Protocols
Integrated systems trigger real-world actions: shutting down critical systems, playing audio/visual alerts, and communicating via mobile networks.
Mobile + App Integration
ShakeAlarm® also pushes alerts to mobile devices through its dedicated app for immediate situational awareness.
Built for Speed, Accuracy, and Survivability
Engineered to perform under pressure, ShakeAlarm® combines fast-acting detection, real-world reliability, and seamless integration to protect people and infrastructure when every second counts.
Dual-Sensor Reliability
Dual-source detection via ShakeAlert® + local sensors ensures no single point of failure.
False Positive Minimization
Machine logic separates non-seismic noise (traffic, machinery) from real threats.
Instant Offline Response
Even when disconnected from cloud or internet services, ShakeAlarm® systems respond instantly.
Over 25 Years Uptime
Rugged hardware with proven reliability in extreme environments.
