Abstract(unpublished)
Several regions of the world already have or are in the process of developing an early warning system (EWS) for earthquakes. As is well known, earthquakes cannot be predicted in the short term. However, an EWS is based on the principle that when a strong earthquake occurs, the initial seismic waves detected by seismographs near the epicentre can be quickly analysed. Once analyzed automatically, an alarm signal can be sent to more distant areas before damaging seismic waves arrive. This alert can then be used to take action before the seismic waves arrive (such as stopping industrial activities for example). In Canada, these technologies are being developed for the Pacific region and Eastern Canada. Quebec is particularly interesting because earthquakes of magnitude 5 are felt at great distances, which increases the warning time when an earthquake occurs. Natural Resources Canada (NRCan) will lead this initiative, in partnership with provincial collaborators. The private sector will also be involved through the development of software and applications. NRCan is therefore reaching out to potential partners in such an earthquake warning system.
