Résumé(disponible en anglais seulement)
Modern strong motion instrumentation with on-board computing capabilities can serve multiple purposes when connected in networks with fast Internet based telemetry. Since the instruments can feed their data directly in to rapid response systems they contribute in an enfolding earthquake to immediate situation awareness long before results from conventional reconnaissance missions become available.
Their data can be integrated with structural monitoring systems to aide in the rapid assessment of critical infrastructure and life lines in the aftermath of a large earthquake. They can also help to fill the often still sparse data-base of strong ground motions required for seismic engineering and hazard and risk assessment in general. All three applications require a sufficiently high density of stations in a high earthquake risk area and as well a new type of smart instrument which can provide a parameter set describing the nature and severity of earthquake ground motion in real time and in a form suitable as input for engineering models.
A network of about one hundred novel instruments in British Columbia delivers parametric ground motion data directly to client systems in near real time without the detour through a seismic data centre. We give an overview of how the network operates and present examples from recent local earthquakes.
