Assessment and prediction of debris-flow hazards Assessment and prediction of debris-flow hazards
Study of debris-flow geomorphology and initiation mechanism has led to better understanding of debris-flow processes. This paper reviews how this understanding is used in current techniques for assessment and prediction of debris-flow hazards.

Mapping debris-flow hazard in Honolulu using a DEM Mapping debris-flow hazard in Honolulu using a DEM
A method for mapping hazard posed by debris flows has been developed and applied to an area near Honolulu, Hawaii. The method uses studies of past debris flows to characterize sites of initiation, volume at initiation, and volume-change behavior during flow. Digital simulations of debris flows based on these characteristics are then routed through a digital elevation model (DEM) to...

Differentiation of debris-flow and flash-flood deposits: implications for paleoflood investigations Differentiation of debris-flow and flash-flood deposits: implications for paleoflood investigations
Debris flows and flash floods are common geomorphic processes in the Colorado Rocky Mountain Front Range and foothills. Usually, debris flows and flash floods are associated with excess summer rainfall or snowmelt, in areas were unconsolidated surficial deposits are relatively thick and slopes are steep. In the Front Range and foothills, flash flooding is limited to areas below about...

Landslides caused by the Klamath Falls, Oregon, earthquakes of September 20, 1993 Landslides caused by the Klamath Falls, Oregon, earthquakes of September 20, 1993
The Klamath Falls earthquakes caused landslides throughout an area of about 420 sq km and as far as about 29 km from the epicenter, a distribution that is typical for magnitude 6 earthquakes (see graphs on following pages). Most of the landslides were rock falls or shallow, highly disrupted rock slides from roadcuts, quarries, and steep bluff faces. Such landslides are also among the...

A rainfall intensity-duration threshold for landslides in a humid- tropical environment, Puerto Rico A rainfall intensity-duration threshold for landslides in a humid- tropical environment, Puerto Rico
Landslides are triggered by factors such as heavy rainfall, seismic activity, and construction on hillslopes. The leading cause of landslides in Puerto Rico is intense and/or prolonged rainfall. A rainfall threshold for rainfall-triggered landsliding is delimited by 256 storms that occurred between 1959 and 1991 in the central mountains of Puerto Rico, where mean annual rainfall is close...

Observations and modeling of seismic background noise Observations and modeling of seismic background noise
The preparation of this report had two purposes. One was to present a catalog of seismic background noise spectra obtained from a worldwide network of seismograph stations. The other purpose was to refine and document models of seismic background noise that have been in use for several years. The second objective was, in fact, the principal reason that this study was initiated and...
