Shakealarm

ShakeAlarm is an on-site earthquake early warning system (EEWS) developed by Weir-Jones Engineering Consultants〔http://www.weir-jones.com〕 in Vancouver, British Columbia. The system functions by detecting and identifying fast moving P-waves that arrive prior to the slower and damaging S-waves generated from the hypocenter of an earthquake. Once ShakeAlarm has identified a candidate P-wave it will determine in less than 500 milliseconds if the following S-wave will be strong enough to be dangerous. Once the determination has been reached that an inbound S-wave might exceed acceptable levels the system can trigger the structured shutdown of critical processes - gas, electricity and water services - and can also be used for opening of fire bay doors, SMS warnings to the general population and a variety of other services to be enacted prior to the S-wave's (shaking) impact. ShakeAlarm represents a streamlined site specific application of technology and ideas that Japan has been working with for some time on a nationwide deployment level in the form of a network.〔Meguro, K 2008, ‘Strategy for Taking Full Advantage of Earthquake Early Warning System for Earthquake Disaster Reduction’, 14th WCEE, Beijing, China, Oct 12-17〕
==Applications==
ShakeAlarm is deployed throughout British Columbia, Washington State and Oregon State - further locations on the West Coast of North America are being investigated for deployment of the ShakeAlarm system.
Shakealarm has been protecting the George Massey Tunnel, (and its 50,000+ daily users) in Delta, BC against significant seismic activity since 2009.〔http://tranbc.ca/2012/07/23/emergency-what-if-scenario-are-highways-prepared-for-earthquakes/#sthash.TmdLL7ff.dpbs〕
