Aerial photograph of catastrophic landslide that occurred near Oso, Washington, March 22, 2014.

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

Bottom: The productivity parameter (a-value) and temporal decay parameter (p-value) for each global tectonic regime shown as a “+” with uncertainty shown by the line of matching color. Figures from Page et al. (2016).
