Sitka Landslide Risk


What is this?

The Landslide Risk Dashboard is a tool to communicate the likelihood of a debris flow at any given time based on a model developed by a team of scientists studying landslides in Sitka, Alaska. The model compares conditions when landslides have occurred in the past in combination with weather forecasts and real-time precipitation measurements to determine the likelihood that a landslide will occur, which is posted as a low, medium, or high landslide risk level. Posted risk levels are combined with recommended actions to guide community members toward emergency preparedness and informed decision making during periods of elevated hazard, with the goal of protecting human life.


This work was funded by the National Science Foundation (grant number 1831770). The project is also detailed on the Sitka Sound Science Center website.
