Building damage caused by a slow landslide in Boyd County, Kentucky, 2017 

Numerous debris flows caused by intense rainfall from Hurricane Maria in September 2017 in Puerto Rico. Trees are bare due to the hurricane force winds that stripped the leaves. 

Shallow landslides damaged homes and closed many roads in the San Francisco East Bay region as a result of storms in January and February, 2017.

Cracks on a gravel road formed during the reactivation of a slow, deep landslide. The cracks can be indicators of local movement in or around the road or in this case, are a sign of a much larger landslide. 

Large cracks formed in this yard after a large landslide occurred downslope of a home. Though the home wasn't directly impacted by the landslide, the cracks in the yard are indicators of potential additional movement and increased landslide risk.

Cracks on a gravel road formed during the initial movement of a slow, deep landslide. The cracks can be indicators of local movement in or around the road or in this case, a much larger landslide and damaged many homes. 

A reactivated landslide destroyed this home that was built on the landslide. Initial, slow landslide movement allowed the occupant to escape. Island County, WA. March 2013
