Description:

Abstract:: Scientific findings of the last several years have shown that the Oregon coast is vulnerable to great (M 8-9) earthquakes that can occur on the offshore cascadia subduction zone fault system. Tsunamis are caused by any large-scale disturbance of the sea floor. These disturbances are generally caused by faulting, landslides, or volcanic eruptions. This project addresses the simultaneous uplift and subsidence of the sea floor accompanying undersea earthquakes on large fault zones termed "subduction zones". The shape of the deformed sea floor after an earthquake is transmitted to the overlying sea surface, forming the initial tsunami wave. A series of 56 U.S. Geological Survey quadrangle-based tsunami hazard maps were produced to implement Senate Bill 379 passed by the 1995 Oregon Legislature and enacted into law as Oregon Revised Statutes (ORS) 455.446 and 455.447. These ORS limit construction of new essential facilities and special occupance structures in tsunami flooding zones. This digital representation of the original series of maps combines all map information into one file. The original hardcopy maps remain the basis for implementing ORS 455.446 and 455.447.
Purpose:: The focus of this digital representation of the original hardcopy maps is to combine the 56 maps into one digital file and enable wider distribution of the tsunami inundation boundary.

Attribute_Accuracy_Report: unknown

Logical_Consistency_Report:

This digital tsunami inundation line is a combination of the original 56 quadrangle-based lines released as separate open file reports. This line has gaps at various points where the tsunami inundation hazard was judged to have such low risk that specifying an inundation zone for the purposes of the legislation was unnecessary. Tsunami effects in these areas, if any, would likely be channel bank splash and higher than normal currents for the waterways involved. The purpose of Senate Bill 379 was not to map all possible tsunami inundation, but to show areas, especially dry land areas, that have a reasonable risk of tsunami damage to critical and essential facilities.

Completeness_Report:

The data set is complete for the purpose of meeting requirements of Senate Bill 379, enacted as ORS 455.446 and 455.447.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: Horizontal positional accuracy is tested by visual comparison of hard copy check plots to the source materials and verifying the location of the data on-screen relative to other data layers in the same geographic area.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:: The maximum vertical positional error is one contour interval on the corresponding U.S. Geological Survey 7½' quadrangle base map.
