Description:
Abstract:
Debris flows, debris avalanches, mud flows and lahars are
fast-moving landslides that occur in a wide variety of environments
throughout the world. They are particularly dangerous to life and
property because they move quickly, destroy objects in their paths,
and can strike with little warning. The purpose of this map is to
show where debris flows have occurred in the conterminous United
States and where these slope movements might be expected in the
future.
Purpose:
These data are intended for geographic display and
analysis at the national level, and for large regional
areas. It is not intended for hazard evaluation or other
site-specific work, and should not be used for such. It can
be used to determine where debris flow processes may be a
problem and where additional information and investigation are
warranted. Although the digital form of the data removes the
constraint imposed by the scale of a paper map, the detail and
accuracy inherent in map scale are also present in the digital
data. The fact that this database was edited at a scale of
1:2,500,000 means that higher resolution information is not
present in the data. Plotting at scales larger than
1:2,500,000 will not yield greater real detail, and it may
reveal fine-scale irregularities below the intended resolution
of the database. Similarly, where this database is used in
combination with other data of higher resolution, the resolution
of the combined output will be limited by the lower resolution
of these data. No responsibility is assumed by the U.S.
Geological Survey in the use of these data.

Currentness_Reference:
All of the data on this map were compiled from reports published
or field work conducted after the year 1928.
No distinction was made between debris flow scars, made shortly
after the events and debris flow deposits, which may be thousands
of years old. We believe that all of the debris flows described
in this report formed during the past 10,000 years (Holocene),
but some of them could be older.

Data_Set_Credit:
We are grateful to several state geologists
and members of their staff who kindly reviewed a preliminary
copy of the map and the bibliography and provided new information.
We are particularly grateful to M. Lee Allison, State Geologist
for Utah, and members of his staff who contributed a digital
database of debris flow locations for Utah. We also wish to thank
Stephen Ellen, Russell Campbell, Gerald Wieczorek, and David
Howell for their reviews and help during various phases of the work.
Native_Data_Set_Environment:
The databases in this repot were compiled in ARC/INFO, a commercial
Geographic Information System (Environmental Systems Research
Institute, Redlands, California), with version 3.0 of the menu
interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon,
1991, Wentworth and Fitzgibbon, 1991). The files are in either
GRID (ARC/INFO raster data) format or COVERAGE (ARC/INFO vector
data) format. Coverages are stored in uncompressed ARC export
format (ARC/INFO version 7.x). ARC/INFO export files (files with
the .e00 extension) can be converted into ARC/INFO coverages in
ARC/INFO (see below) and can be read by some other Geographic
Information Systems, such as MapInfo via ArcLink and ESRI's ArcView
(version 1.0 for Windows 3.1 to 3.11 is available for free from
ESRI's web site:
http://www.esri.com). The digital compilation was
done in version 7.0.4 of ARC/INFO with version 3.0 of the menu
interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon,
1991, Wentworth and Fitzgibbon, 1991).
