Sensors detect California cliff collapses hours to days before failure, report says

Following a four-year study, scientists at UC San Diego's Scripps Institution of Oceanography released a new report to determine whether an early warning system could detect a landslide before it happens.

The "California Coastal Landslide Early Warning Research" report found that a network of in-ground sensors can provide a reliable warning of impending, dangerous landslides with hours to days' notice, but that more work is needed to formalize the findings into an actionable warning system.
