REDUCING LANDSLIDE HAZARDS IN THE UNITED STATES Debris-Flow Hazards in the San Francisco Bay Region Some landslides move slowly and cause damage gradually, but others move so rapidly that they can destroy property and take lives suddenly and unexpectedly. Debris flows (also referred to as mudslides, mudflows, or debris avalanches) are.

General. Debris-Flow Hazards in the San Francisco Bay Region Reducing Landslide Hazards in the United States Fast moving flows of mud and rock, called debris flows or mudslides, are among the most numerous and dangerous types of landslides in the San Francisco Bay region.

This map identifies the principal areas in the San Francisco Bay region that are likely to produce debris flows, which are also called "mudslides." Debris flows that occur in the bay region are fast-moving downslope flows of mud that may include rocks, vegetation, and other debris.

These flows begin during intense rainfall as shallow landslides on steep slopes. These maps show, for emergency service managers in the San Francisco Bay region, the threshold rainfall that may be capable of triggering a level of debris-flow activity likely to threaten public safety.

The maps are products of a continuing series of studies that began after a catastrophic storm on Januarytrigge debris flows in the San Francisco Bay region, causing 25 Author: R.C.

79, no. 45 (Supplement), p. F Geomorphology and Natural Hazards Hazards along a river course in a drainage basin are characterized by three types of events: debris flow, turbidity flow and flood.

Each has its own channel segment with different sediment transport processes. For Hawaii, the San Francisco Bay region, and Sierra Nevada-Great Basin region of California. Although reliable rainfall/debris-flow thresholds exist for the San Francisco Bay region, climatic dissimilarities between there and southern California produce differ-ences in the thickness, character, and behavior of the hillslope materials that necessi-tate adjustment of the thresholds.

Geological Survey map of Puerto Rico shows the relative risks of landslides due to the kind of intense rainfall brought on by hurricanes. It identifies 20% of the island as at high risk, 9% at very high risk, and 1% at extremely high risk of landslides under those conditions.
