Year in Review We have just begun the second year of the landslide warning system design, and many of you are aware that the research team was recently in town conducting a variety of workshops, informal events, and meetings. This…
Landslides are hard to predict. Better scientific information can improve predictions, but there will always be a tension between failed and false warnings. False warnings occur when a landslide is predicted but does not occur. Failed warnings happen when a…
Sitka Sound funnels wind and rain into Sitka by the aid of a natural phenomenon called atmospheric rivers (ARs). These “rivers” are narrow bands of saturated air that are steered by prevailing winds and can deliver days’ worth of rain…
We’ve had a productive summer of installing soil moisture sensors and a weather station that may enhance our understanding of when landslides occur. While crucial elements to a landslide warning system (LWS), these sensors aren’t the only…
Summer has already been a time of many milestones for landslide research in Sitka. Our first high elevation weather station is up and running with real-time data collection rolling in this fall. Data receiving antennas were installed at…
The Harbor Mountain weather station mentioned in our last blog post is up, and once operational, will provide data on wind speed and direction, precipitation, temperature, humidity, and snow depth. Gabriel Wolken and Ronald Daanen with the…
To aid in predicting landslide risk for the landslide warning system, Professor Josh Roering is installing several low-cost, low-power soil moisture sensors into the ground. Beginning in mid-June, he and others will be in Sitka on the Mount…
