As California community slowly slides toward ocean, not all homeowners want to leave

Sheri Hastings' property sits on a slow-moving disaster; a complex of landslides in the Portuguese Bend area of Rancho Palos Verdes, California.

For nearly 70 years, this area has shifted roughly a few inches a year, but recently that pace has surged to as fast as four inches a week. 

The culprit for the spike in movement is heavy rains – and runoff from nearby canyons -- brought on by a series of recent atmospheric rivers that have soaked deep into the soil, destabilizing the area.
