Seismic Landslide Hazard for the City of Berkeley, California Seismic Landslide Hazard for the City of Berkeley, California
This map describes the possible hazard from earthquake-induced landslides for the city of Berkeley, CA. The hazard depicted by this map was modeled for a scenario corresponding to an M=7.1 earthquake on the Hayward, CA fault. This scenario magnitude is associated with complete rupture of the northern and southern segments of the Hayward fault, an event that has an estimated return period...
Geologic Map of the Hellas Region of Mars Geologic Map of the Hellas Region of Mars
INTRODUCTION This geologic map of the Hellas region focuses on the stratigraphic, structural, and erosional histories associated with the largest well-preserved impact basin on Mars. Along with the uplifted rim and huge, partly infilled inner basin (Hellas Planitia) of the Hellas basin impact structure, the map region includes areas of ancient highland terrain, broad volcanic edifices...
Interpretive geologic cross sections for the Death Valley regional flow system and surrounding areas, Nevada and California Interpretive geologic cross sections for the Death Valley regional flow system and surrounding areas, Nevada and California
This report presents a network of 28 geologic cross sections that portray subsurface geologic relations within the Death Valley regional ground-water system, a ground-water basin that encompasses a 3? x 3? area (approximately 70,000 km2) in southern Nevada and eastern California. The cross sections transect that part of the southern Great Basin that includes Death Valley, the Nevada Test...
Geologic maps and cross sections of mine levels at the Pea Ridge iron mine, Washington County, Missouri Geologic maps and cross sections of mine levels at the Pea Ridge iron mine, Washington County, Missouri
This geologic mapping and interpretation of the Pea Ridge iron mine, Missouri, is part of a cooperative effort between the U.S. Geological Survey (USGS) and the Missouri Department of Natural Resources, Division of Geology and Land Survey (DGLS), under the auspices of the USGS Midcontinent Strategic and Critical Minerals Project. The goal of the Pea Ridge study is to compare the Middle...
