Canada: Earthquake sensor network aims to give B.C. crucial seconds to prepare for the 'Big One'
[...]
A network of eight underwater sensors and 32 land-based seismic and GPS sensors on Vancouver Island is up and running and could make all the difference when a big earthquake hits.
[...]
The system will estimate how powerful an earthquake is and issue a warning to a network of alarms across B.C. —indicating how much time [there is] before the destructive shockwaves hit.

Scientists are preparing for the so-called "Big One." That's the magnitude 9.0 megathrust earthquake that will happen along the Cascadia subduction zone off the coast of Vancouver Island.
When it does, Ocean Networks Canada's sensors will pick up the earthquake's waves of energy at the moment they are triggered. Those sensors will then send a warning to the rest of the South Coast that will get there up to 90 seconds before the destructive shock waves arrive.
