Charlevoix Seismic Zone Charlevoix Seismic Zone The Charlevoix Seismic Zone is a seismically active area in the Charlevoix region of northeastern Quebec, Canada. It is also known as the Charlevoix-Kamouraska Seismic Zone because earthquakes occur in Kamouraska County where the land expression of the seismic zone is separated by the Saint Lawrence River. Much seismic activity takes place under the river. With over 200 small earthquakes occurring each year, the Charlevoix Seismic Zone is one of the most active seismic zones in Canada. Since 1663, five damaging earthquakes have occurred in the area, including a magnitude 7.3-7.9 event in 1663, a magnitude 7.0
Seismic metamaterial the electromagnetic energy is in effect directed around an object, or hole, and protecting buildings from seismic waves employs this same principle. Giant polymer-made split ring resonators combined with other metamaterials are designed to couple at the seismic wavelength. Concentric layers of this material would be stacked, each layer separated by an elastic medium. The design that worked is ten layers of six different materials, which can be easily deployed in building foundations. As of 2009, the project is still in the design stage. For seismic metamaterials to protect surface structures, the proposal includes a layered structure of metamaterials, separated
