California officials have released a color-coded statewide map depicting regions most at risk for landslides.
The landslide risk map made public by the California Geological Survey, is meant to give first responders and the public a general idea of where landslides are more likely to occur to assist infrastructure owners, emergency planners and the public in planning. It does not allow users to zoom in on specific neighborhoods or streets.
The coastal mountain region between Los Angeles and San Francisco is deemed at high risk.
Risk was calculated by identifying regions that have weak rocks and steep slopes, and well past landslides have occurred. It does not take into account the risk of landslide caused by rainstorms or earthquakes.
“On the most basic level, weak rocks and steep slopes are more likely to generate landslides,” CGS said.
Overall in the United States, landslides kill about 25 to 50 people every year and cause over $2 billion in damage.
