I routinely assess geology hazards: landslides, erosion, debris flows, channel migration, tsunami, soil liquefaction and even avalanches. Here's a geology hazard I have not dealt with: sand burial. This via Cliff Mass via Brad Smull and picture by Jason Durret.
The location is on the coast of Oregon at Waldport.
Not a particularly safe home site area on a sand spit. Throw in the tsunami risk, subduction quake subsidence risk and the long term prospects for these homes is not good. But in the short term a very wonderful sandy beach to live by - perhaps a little too much sand.
