The methodology used to create the liquefaction map of Laval was the HAZUS methodology developed by the US Department of Homeland Security. This methodology provides an equation with four variables to calculate the probability of liquefaction based on the earthquake magnitude, ground conditions, and liquefaction susceptibility of the map units. The map shows that the sediments in Laval have low to none liquefaction susceptibility. For a magnitude 6 earthquake, the highest probabilities of liquefaction are around 3% in low susceptibility zones.
