Jeffrey Coe
Biography
I began my career at the USGS in 1988 and joined the Landslide Hazards group in 1996. Early in my career, I was fortunate to work on an assortment of geologic problems (paleoseismology, structural geology, debris-flow hazards) related to the proposed Yucca Mountain Nuclear Waste Repository in Nevada. I’ve been able to utilize this broad base of experience in the Landslide Hazards group, where I’ve worked on a wide variety of landslide types and topics in the US and abroad. I’m currently the chief of the Landslide Magnitude and Mobility research project based in Golden, CO. My broad research focus is on understanding landslide processes and quantifying landslide hazards. I’m currently interested in gaining a better understanding of the impact that climate change will have on landslide hazards.

Landslides Mapped from LIDAR Imagery, Kitsap County, Washington
Landslides are a recurring problem on hillslopes throughout the Puget Lowland, Washington, but can be difficult to identify in the densely forested terrain. However, digital terrain models of the bare-earth surface derived from LIght Detection And Ranging (LIDAR) data express topographic details sufficiently well to identify landslides. Landslides...
McKenna, Jonathan P.; Lidke, David J.; Coe, Jeffrey A. Probabilistic Methodology for Estimation of Number and Economic Loss (Cost) of Future Landslides in the San Francisco Bay Region, California
The Probabilistic Landslide Assessment Cost Estimation System (PLACES) presented in this report estimates the number and economic loss (cost) of landslides during a specified future time in individual areas, and then calculates the sum of those estimates. The analytic probabilistic methodology is based upon conditional probability theory and laws...

Initiation conditions for debris flows generated by runoff at Chalk Cliffs, central Colorado
We have monitored initiation conditions for six debris flows between May 2004 and July 2006 in a 0.3 km2 drainage basin at Chalk Cliffs; a band of hydrothermally-altered quartz monzonite in central Colorado. Debris flows were initiated by water runoff from colluvium and bedrock that entrained sediment from rills and channels with slopes...
Coe, Jeffrey A.; David Kinner; Godt, Jonathan W. Mass Wasting Following the 2002 Missionary Ridge Fire near Durango, Colorado, a Field Trip Guidebook
This field trip guide focuses on mass wasting following the 2002 Missionary Ridge fire near Durango, Colorado. We prepared this guide to accompany a May 4, 2006, field trip during the second Roy J. Shlemon Specialty Conference, which was held in Durango, Colorado, May 3-5. The conference, entitled Mass Wasting in Disturbed Watersheds, was...

Field Reconnaissance of Debris Flows Triggered by a July 21, 2007, Thunderstorm in Alpine, Colorado, and Vicinity
On the evening of July 21, 2007, a slow-moving thunderstorm triggered about 45 debris flows on steep mountainsides near the community of Alpine, Colorado. Most of the debris flows were initiated by surface-water runoff that eroded and entrained loose sediment in previously existing channels. About 12 of the debris-flow channels were located in the...
Coe, Jeffrey A.; Godt, Jonathan W.; Wait, T.C.; Kean, Jason W. Preliminary Assessment of Landslides Along the Florida River Downstream from Lemon Reservoir, La Plata County, Colorado
Nearly two-dozen shallow landslides were active during spring 2005 on a hillside located along the east side of the Florida River about one kilometer downstream from Lemon Reservoir in La Plata County, southwestern Colorado. Landslides on the hillside directly threaten human safety, residential structures, a county roadway, utilities, and the...

Coe, Jeffrey A.; Harp, Edwin L.; Tarr, Arthur C.; Michael, John A. Probabilistic assessment of precipitation-triggered landslides using historical records of landslide occurrence, Seattle, Washington
Ninety years of historical landslide records were used as input to the Poisson and binomial probability models. Results from these models show that, for precipitation-triggered landslides, approximately 9 percent of the area of Seattle has annual exceedance probabilities of 1 percent or greater. Application of the Poisson model for estimating the...
Coe, Jeffrey A.; Michael, J.A.; Crovelli, R.A.; Savage, William U.; Nashem, W.D.; Laprade, W.T. Map showing recent (1997-98 El Nino) and historical landslides, Crow Creek and vicinity, Alameda and Contra Costa Counties, California
This report documents the spatial distribution of 3,800 landslides caused by 1997-98 El Ni?o winter rainfall in the vicinity of Crow Creek in Alameda and Contra Costa Counties, California. The report also documents 558 historical (pre-1997-98) landslides. Landslides were mapped from 1:12,000-scale aerial photographs and classified as either debris...

Messerich, James A.; Coe, Jeffrey A. Map showing alpine debris flows triggered by a July 28, 1999 thunderstorm in the central Front Range of Colorado
This 1:24,000-scale map shows an inventory of debris flows that were triggered above timberline by a thunderstorm in the central Front Range of Colorado. We have classified the debris flows into two categories based on the style of initiation processes in the debris-flow source areas: 1) soil slip, and 2) non-soil slip erosive processes. This map...
