(Map from Shannon & Wilson South Kramer report) The state is . The Seattle, Washington, area is known for its livability and its magnificent natural setting. The city and nearby communities are surrounded by an abundance of rivers and lakes and by the bays of Puget Sound. Two majestic mountain ranges, the Olympics and the Cascades, rim the region. These dramatic natural features are products of dynamic forces-landslides, earthquakes, tsunamis, glaciers.

In Alaska, these hazards occur primarily in the portion of FRPA Region I (coastal forests) from Cordova south. Triggered by the earthquake of 27 March3 x cubic meters of rock fell meters, then slid at high speed 5 kilometers across the nearly level Sherman glacier near Cordova.

The landslide has a number of significant new features in addition to those typical of other large landslides that may have slid on a layer of trapped and compressed air. Research in southeast Alaska has identified soil mass movement as the dominant erosion process, with debris avalanches and debris flows the most frequent events on characteristically steep, forested slopes.

In this work, field measurements of the soil saturation in a sample slope, coming from 18 months continuous monitoring of soil water content, are presented. The experimental data are compared with the seasonal trends of the soil saturation resulting from the application of a simplified empirical model, based on rainfall and air temperature Author: Roberto Valentino, Massimiliano Bordoni, Claudia Meisina, Davide Zizioli, Marco Bittelli, Silvia Che.

Extreme and/or prolonged rainfall events frequently cause landslides in many parts of the world. In this study, infiltration of rainfall into an unsaturated soil slope and triggering of landslides is studied through laboratory model (flume) tests, with the goal of obtaining the triggering rainfall intensity–duration (I–D) threshold.

The Alaska Region represents a resource-rich, dynamic landscape shaped by volcanos, earthquakes, major rivers, and glaciers. Here, we conduct research to inform management of Alaska’s extensive natural resources, inform national Arctic energy policy, and provide scientific information to help others understand, respond to, and mitigate impacts from natural hazards.
