Corporate Overview

Since 2000, we have been developing, manufacturing and selling QuakeGuard™ products and services, which provide warning of earthquakes to commercial, residential, industrial and government customers. QuakeGuard products reduce property damage, protect equipment, and prevent injuries and loss of life:

  • Programmable audio and visual alarms prevent injuries.
  • Automated control of emergency systems, mission-critical equipment, and other systems protects assets and reduces disruption of services.

QuakeGuard products use patented sensing technology to detect and analyze P-wavesPrimary, or P, waves are the fastest moving waves produced by an earthquake and are first to arrive. They do not carry much energy and cause only slight shaking. (the non-destructive primary earthquake waves) to estimate the intensityDescribes how violently the ground shakes during an earthquake. of the earthquake so that actions can be taken before serious shaking starts.

The QuakeGuard Network is fast enough to produce a warning before serious ground motions begin, even at the epicenter. This capability has been successfully demonstrated during earthquakes at customer locations in California and most recently during the South Napa earthquake on August 24, 2014.
