Earthquake Early Warning That Saves Lives

ShakeAlarm® is a high-reliability earthquake early warning system engineered to deliver critical alerts in seconds. Built for schools, infrastructure, and industrial applications.

ShakeAlarm® delivers critical seconds of advance warning before the S – waves arrive, helping protect people, assets, and infrastructure. ShakeAlarm® is a standalone Earthquake Early Warning System (EEWS) that provides reliable and immediate alerts before the most damaging waves of an earthquake reach your location.

Designed to reduce false alarms, it connects to both the USGS ShakeAlert® as a responding device on the USGS ShakAlert network and, as ShakeAlarm, equipped with local sensors (accelerometers or geophones) for increased speed and precision for high value pieces of infrastructure when response time is critical. This advanced solution integrates seamlessly with your infrastructure’s emergency systems—allowing critical seconds for evacuation alerts, gas shut-off, and life-saving protocols.

Deployed Where It Matters Most

Schools & Campuses

Earthquakes often strike without warning, leaving students vulnerable. ShakeAlarm® automatically triggers Duck & Cover protocols, plays audible alerts over PA systems, and even connects to smart signage, allowing for orderly evacuation or in-place safety measures in seconds.

Municipal Buildings & Government

Government operations must remain functional during and after seismic events. ShakeAlarm® initiates automated building-wide alerts, shuts down non-critical systems, and notifies key personnel, ensuring staff safety and operational continuity.

Energy & Utilities

Gas lines, transformers, and pressurized systems pose serious risks in a seismic event. ShakeAlarm® integrates with control systems to shut off electricity and gas before the S-wave arrives, minimizing fire risk and potential infrastructure failure.

Transportation & Rail

Transit systems face catastrophic risk during earthquakes. ShakeAlarm® can instantly slow or stop trains, lock crossing signals, and alert control rooms—preventing derailments, collisions, and infrastructure collapse.

Commercial & Residential

From high-rise condos to multi-tenant offices, ShakeAlarm® helps protect both people and property. Pre-programmed alerts can open fire doors, disable elevators, and notify building management—all within seconds.

Varius is our key American partner for deploying both ShakeAlert and ShakeAlarm Earthquake Early Warning Systems (EEWS) and of course, ShakeMonitor Structural Health Monitoring Systems in the Pacific Northwest. Varius is designed to bring clients a level of expertise and experience that is often not available using conventional business practices. Our goal is to bring you the best technology and to use it as a tool that supports experience, thoughtfulness, and inspiration. Engineers often look for solutions in spreadsheets and on CAD screens without recognizing that these are simply tools that should be used to complement imagination and experience. We never lose sight of the things that inspire great design or produce unique solutions, and it is much more than a mouse and a keypad. We offer peer review services that often reveal hidden design opportunities, saving money, reducing risk, and performing better. Our earthquake early warning technology is a technological tour-de-force and should be implemented by every organization, industry, and business with assets to protect and lives to save.
