FACT: What will happen in the Cajon Pass
The study estimates that there will be five moderate landslides in the Cajon Pass, moving one- to 15-million cubic meters of rock and soil.
A worst-case scenario projects that the 15 Freeway shifts and both the north and southbound lanes are displaced.
There could be up to 73,000 cubic meters of debris on the freeway.
More than 111,000 commuters are expected to be trapped.
Railroad lines will also be uprooted and buried under debris.
A 36-inch gas line could be displaced at up to four locations. Other buried petroleum product lines and fiber-optic communication lines are expected to be displaced by landslides and/or buried by debris at multiple locations.
