Volcanoes of Alaska

Alaska Volcano Observatory, 1998, Volcanoes of Alaska: Alaska Division of Geological & Geophysical Surveys, Information Circular 38 (1 sheet, 1:4,000,000)

A poster-style map of historically active volcanoes and other volcanic centers in Alaska, including photographs of selected volcanoes. The map poster also includes descriptions and illustrations of the tectonic setting of Alaska, recent notable eruptions, volcano hazards, and a glossary. This map is ideal for classroom use.

Geologic map of the island of Hawaii

Wolfe, Edward W., and Morris, Jean (eds.), 1996, Geologic map of the island of Hawaii: U.S. Geological Survey Miscellaneous Investigations Series Map I-2524-A (3 sheets 1:100,000; booklet 18 p.)

Wolfe, Edward W., and Morris, Jean (eds.), 1996, Sample data for the geologic map of the island of Hawaii: U.S. Geological Survey Miscellaneous Investigations Series Map I-2524-B (3 sheets 1:100,000; booklet 15 p.)

This is the first map of the entire Island of Hawai`i to show in detail the age and distribution of both prehistoric and historic lavas. The map is a compilation of geologic mapping from 1975 through 1988 by approximately 20 geologists, with subsequent updates for Kilauea lavas emplaced through April 20, 1995, in a continuing eruption. Its chronologic detail reflects the application of isotopic-dating techniques that were unavailable when its predecessor was made in 1946.


Lava flow hazards on the island of Hawai`i

Wright, Thomas L., Chun, Jon Y.F., Esposo, Joan, Heliker, Christina, Hodge, Jon, Lockwood, John P., and Vogt, Susan M., 1992, Map showing lava-flow hazard zones, Island of Hawaii: U.S. Geological Survey Miscellaneous Field Studies Map MF-2193.

This map shows lava-flow hazard zones for the five volcanoes on the Island of Hawai`i (Kilauea, Mauna Loa, Mauna Kea, Hualalai, Kohala). The hazard zones are based chiefly on the location of eruptive vents, areas covered by past lava flows as revealed by geologic mapping and historic observations, and topography. The maps shows nine lava-flow hazard zones and the boundaries between the zones are approximate because the degree of hazard from one zone to the next is generally gradual rather than abrupt, and the change can occur over the distance of a mile or more. This map updates an earlier hazard assessment published in 1974 and revised in 1987.



Long Valley vicinity, California

Bailey, Roy A., 1989, Geologic map of the Long Valley Caldera, Mono-Inyo Craters Volcanic Chain, and vicinity, Eastern California: U.S. Geological Survey Miscellaneous Investigations Series Map I-1933 (2 sheets 1:62:500; booklet 11 p.)

Long Valley caldera is currently the most restless volcano in the conterminous United States. The rugged landscape of the Long Valley region owes its beauty and appeal to the striking geologic features created largely by the growth of the imposing Sierra Nevada mountains to the west and volcanic eruptions. This geologic map shows the youngest faults and volcanic landforms and rock deposits that were formed in this area during the past 3.6 million years as well as the much older rocks that underlies the area (dating back to about 240 million years). The map identifies eruptive products created by the caldera-forming and subsequent eruptions as well as from the Mono-Inyo Crates volcanic chain that cuts through the caldera. The accompanying booklet provides an overall geologic and glacial history of the area.



Hydrologic Hazards at Mount Rainier, Washington

Scott, Kevin M., and Vallance, James W., 1995, Debris flow, debris avalanche, and flood hazards at and downstream from Mount Rainier, Washington: U.S. Geological Survey Hydrologic Atlas 729 (2 sheets, booklet 9 p.)

Mount Rainier volcano has produced many large debris flows and debris avalanches (also called lahars and landslides) during the past 10,000 years, and many traveled more than 100 kilometers to inundate parts of the now-populated Puget Sound Lowland. Two maps are included in the atlas. One map illustrates the types, probabilities, and risks of the most dangerous types of debris avalanches and debris flows. Based on 3 characteristic types of events of a known size and estimated frequency, the map shows potential future inundation areas for all rivers draining Mount Rainier. A second map shows examples of smaller debris avalanches and debris flows that occurred in the 20th century. The booklet describes the three characteristic type of events that were used to estimate future inundation areas and factors affecting the risk analysis.
