British Columbia Earthquake Early Warning System

Abstract eng:
An earthquake early warning system has been developed and implemented in the Province of British Columbia in Western Canada. The system was developed in collaboration between UBC, The Roman Catholic Archdiocese of Vancouver and the BC Ministry of Education. The system was originally developed for BC Schools, and has since been expanded to other government institutions, at Municipal, Regional and Provincial levels. The system is based on development of a new, low cost seismic sensor that operates over a network. This provides both local warning at the sensor site and a regional warning over the network. The system is made up of both sensor sites (with two early warning sensors installed) and alarm sites. The alarm sites connect back to the central server over the internet, and once an early warning message is received the alarm is triggered either through sirens or the local public address system. Currently the system includes more than 30 sensor sites and 50 alarm sites. The system includes the capability to provide the messages over the internet and cell networks. This paper describes details of the system, and an example from a Mw 4.7 Earthquake that triggered this system in December 2015.
