PG&E Adds Earthquake Early Warning System to Some Elevators at its Headquarters

Pacific Gas and Electric Company (PG&E) today announced that it has successfully deployed a commercial-grade earthquake early warning (EEW) system on a bank of four elevators at its downtown San Francisco headquarters.

The 34-story office building located at 77 Beale St. in the heart of San Francisco’s Financial District is now the first high-rise building on the West Coast to have elevators equipped with immediate, automated recall.

In the event of a strong earthquake, the four elevator cars connected to the EEW system will receive a warning signal up to one minute before shaking begins and automatically stop at the closest floor and open the doors, enabling passengers to safely exit the elevator before shaking occurs.

Earthquake early warning is intended to identify and characterize an earthquake a few seconds after it begins, calculate the likely intensity of ground shaking that will result, and deliver warnings to people and infrastructure in harm's way via PA system, computer, smartphone, and eventually, via television and radio. The amount of warning time at a particular location depends on its distance from the earthquake epicenter.

“This is a tremendous milestone in PG&E’s effort to incorporate earthquake early warning into our emergency management and preparedness efforts and an important, proactive step in protecting employees and minimizing potential injury to personnel,” said Barry Anderson, vice president, Electric Distribution, PG&E.

In May, Anderson was appointed by California Gov. Jerry Brown to the state’s EEW Advisory Board, which includes the director of the Governor’s Office of Emergency Services (Cal OES) and other state officials.

Over the past year, PG&E worked closely with Seismic Warning Systems (SWS) – a privately held earthquake warning developer and integrator – to install sensors, equipment and communications capabilities at its headquarters.
