Outside of the six communities that Ḵutí partners with (Yakutat, Hoonah, Klukwan, Skagway, Craig and Kasaan), some of our partners are working on (non-Ḵutí) geohazards research in other communities in the region, like those collected below:
The Sitka Landslide Dashboard initiative pre-dates the Ḵutí project and is the culmination of years of landslide research in Sitka after its 2015 fatal landslide. It is being updated and maintained by the Sitka Sound Science Center under a USGS grant.
The Sitka Landslide Dashboard is a web-based dashboard to communicate landslide early warning based on the current and forecast likelihood of landslides. The warnings are generated from models developed by a team of scientists studying landslides in Sitka, Alaska. The level of risk is based on the National Weather Service’s current and forecast rainfall from the Sitka Airport and historical landslide information gathered over the past 20 years. The dashboard also includes maps of landslide susceptibility, which convey hazardous areas in Sitka from landslide runout zones. The model compares conditions when landslides have occurred in the past in combination with observed precipitation measurements to determine the likelihood that a landslide will occur, which is converted to 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. More system information can be found in the publication “Landslide initiation thresholds in data-sparse regions: application to landslide early warning criteria in Sitka, Alaska, USA”.
Through funding from NOAA and the Alaska Sea Grant, the Ḵutí project is able to support landslide runout modeling efforts in two other communities in Southeast Alaska: Petersburg and Wrangell.
