Locating the Seattle Fault in Bellevue, WA: Combining geomorphic indicators with borehole data
The Seattle Fault is an active east-west trending reverse fault zone that intersects both Seattle and Bellevue, two highly populated cities in Washington. Rupture along strands of the fault poses a serious threat to infrastructure and thousands of people in the region. Precise locations of fault strands are still poorly ...
Investigating the Eastern Extent of the Seattle Fault Zone through Depth to Bedrock and Borehole Analysis in Bellevue, Washington
This study identifies lineaments that indicate fault activity and strengthens previous interpretations of structures within the eastern extent of the Seattle Fault zone in Bellevue, WA. My investigation has compiled geotechnical subsurface data, high-resolution LiDAR imagery, and ground-penetrating radar to produce strip log ...
Locating a strand of the Seattle Fault Zone in southeast Seattle, Washington through topographic analysis, borehole analysis and ground penetrating radar
Contributing to the evaluation of seismic hazards, a previously unmapped strand of the Seattle Fault Zone (SFZ), cutting across the southwest side of Lake Washington and southeast Seattle, is located and characterized on the basis of bathymetry, borehole logs, and ground penetrating radar (GPR). Previous geologic mapping and ...
Geophysical Investigation of a Geologic Unconformity at Seward Park - Seattle, WA
This report presents the results of field and geophysical analyses of a geologic unconformity located within Seattleís Seward Park. The unconformity consists of an apparently abrupt contact between Quaternary Vashon till in the north and Tertiary bedrock to the south. Seward Park is located in the middle of the Seattle Fault ...
Predicting the Position of Fault Strands through Borehole Correlation of the Top of Tertiary Bedrock in the Seattle Fault Zone, Seattle, Washington
Only a few strands of the Seattle Fault Zone have been identified on land in Seattle, Washington due to heavy manipulation of the landscape by repeat glaciations, geomorphic reworking, and the interference of the growing metropolitan community concealing potentially dangerous active faults below the surface. Previous ...
