1998 – Results from The Earthquake Preparation, Alarm and Response System for Sydney Water Corporation, 1992 to 1998

Gary Gibson, Wayne Peck, Ian Landon-Jones and Kumara Arachchi

One of the first seismograph networks designed specifically to record local earthquakes was installed about Sydney in 1958. This network was converted to telemetry in 1983. In 1992, Sydney Water Corporation upgraded the network, integrating the functions of earthquake location and magnitude, measurement of the response of structures to earthquake motion, and provision of information for emergency response. The response function has been developed over the past six years, and is now an “Earthquake Preparation, Alarm and Response” system that provides customised information very soon after any significant event.
