Earthquake countermeasures. Seismic sensors detect the tremors of an earthquake and safely stop the elevator at the closest floor. There is a P-wave sensor which detects the initial tremors, and an S-wave sensor that detects the main tremors. WebIn many earthquake prone areas of the country, local codes require special earthquake features on elevator systems. These may include seismic switches which detect movement and shut down the elevator. Hurricanes.
