The fault runs very near to populated areas when offshore, hence there is high potential for infrequent large and damaging earthquakes.

The San Andreas system and the ECSZ take up around 85% of the deformation, while the CCB accommodates the rest.

[note 1][4][7] The fault begins in San Diego Bay, then runs through La Jolla before turning offshore.

However, due to the lack of reports in the area, it is not possible to guarantee that this earthquake occurred on the Rose Canyon Fault.

[23] The Rose Canyon Fault Zone can produce large earthquakes which can be very destructive due to its proximity to major population centers in Southern California.

[23] Scenarios modeling a magnitude 6.9 earthquake predict peak ground acceleration will reach 0.55 g in San Diego, and 0.35 g in Tijuana.
