- Abstract:
-
The objective of this project was to collect and
consolidate data on Oregon landslides associated
with severe storm events in February 1996,
November 1996, and December 1996/January 1997.
The February storm event resulted in 26 FEMA
disaster declared counties, the November event
resulted in 3, and the December/January storms 14.
Over 98% of the landslides were recorded in the
western portion of the state, mainly in the Coast
Range and Cascade Province with fewer in the
Willamette Valley and Klamath Mountains. 9582
slide locations are included in the database, with
varying amounts of information reported for each.
The products of this study are (1) a digital
Geographic Information System (GIS) inventory of
Oregon landslide locations, (2) a spreadsheet
version of the inventory, and (3) an explanatory
text.
- Purpose:
-
The impetus for developing this database was a
desire to better document the magnitude and
distribution of landslide occurrences throughout
Oregon. The resulting inventory provides both
technical and non-technical users with
readily-accessible data for exploring landslide
issues. It is hoped that the data will lead to a
greater understanding of regional landslide issues
and assist in efforts to minimize the threat to
public health and property that landslides can
pose. The digital products of this study are
intended to provide a starting point for future
landslide-related studies.

The spatial accuracy of the GIS polygons, lines,
and points varies significantly from source to
source depending on the means of collecting and
incorporating the location information. Examples
of how entries were added to the GIS include
digitizing marks noted on USGS 7.5-minute
quadrangles and other base maps, importing
source-provided coordinates, and determining
polygon outlines from aerial photographs. Many of
the locations are approximate and should be used
as a general reference only.
