Surficial geology of the Juneau urban area and vicinity, Alaska, with emphasis on earthquake and other geologic hazards

Description

Surficial geology of the Juneau urban area and vicinity, Alaska, with emphasis on earthquake and other geologic hazards, Open-File Report 72-255, presents results from a geologic study of surficial deposits in and near the Juneau urban area. The map area covers parts of the Juneau A-2, B-2, and B-3 quadrangles. The map and tables in the accompanying report show the distribution of the geologic formations, some of their physical properties, uses, and probable reactions to a severe earthquake. However, it is not the purpose of this study to predict in detail how an earthquake would affect any one place. The interpretations shown in the accompanying table should be regarded as indications of how certain geologic deposits will behave during an earthquake. Many of them are based on the behavior of similar deposits during earthquakes elsewhere, and others are based on laboratory tests of the physical properties of certain deposits. The unpredictability of magnitude, acceleration, direction, period of seismic energy, and the distance of an earthquake epicenter from Juneau makes an unqualified prediction of ground behavior impossible. The investigation is part of a 1972 earthquake hazards study in Alaska coastal communities by the U.S. Geological Survey. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/10955.
