Prone to Earthquake? Slide? Liquification?

King County now provides hazard maps and data for flood, dam failure, earthquake, liquefaction, lahar, severe weather, wildfire, and landslide. Click here to view Hazard Maps on King County’s website.

The good news is that we are safe from most of these problems but there are landslide areas on Finn Hill and precautions should be taken.

The map is based on a variety of criteria including any area with a combination of greater than 15% slope, impermeable soils with frequent bands of granular soil, and springs or groundwater seepage. Historic and geologic evidence of movement or debris.

Lots of rain can make many areas slide but these are are of higher likelihood.
