Earthquake

Montréal is in one of Québec’s 3 highest earthquake risk zones. The western Québec seismic zone includes the Ottawa Valley from Montréal to the Témiscamingue region, as well as the Laurentians and eastern Ontario. Potential impacts include landslides, damage to buildings, bridges and roads, power shortages, water main breaks and industrial accidents.

Every year, Montréal invites the population to participate in a province-wide awareness-raising event known as La Grande Secousse du Québec. The Great ShakeOut tells you how to protect yourself during an earthquake and how to recover once it’s over.
