The impact of an earthquake will not respect borders. Much less, a quake that will be registered in the fault of the Rose Canyon. For the past five years, researchers and authorities on both sides of the border have been preparing a seismic and damage scenario for the San Diego-Tijuana region, the findings of which will be presented to the population next March. The purpose is to know what would happen if there is an earthquake of magnitude 6.9 in this fault that passes through the center of the city of San Diego and is projected to Tijuana.
