Isopach map showing Quaternary deposits in the Gulf of Santa Catalina area, California
The Gulf of Santa Catalina is part of the California Continental Borderand, an active transform margin characterized by narrow shelves, steep slopes, and deep closed basin separated by shallow banks and islands. The Gulf of Santa Catalina extend from Point Fermin south to San Diego. It is bounded on the west by prominent bedrock ridges, 30 to 45 km offshore, compromising Santa Catalina Island and

Logs of exploratory trenches through liquefaction features on late Quaternary terraces in the Obion River Valley, northwestern Tennessee
From December 1811 to February 1812, four large earthquakes (mb≥7.0) occurred in the New Madrid (Missouri) Seismic Zone (NMSZ). These have been the largest historical earthquakes in eastern North America. Although this area has been the focus of considerable seismological research, estimates of the repeat time of large-magnitude seismic events remain poorly constrained. Past estimates were primari
Magnetic anomaly map of the central Cayman Trough, northwestern Caribbean Sea
This is the first large-scale published map of magnetic anomalies in the central Cayman Trough area. Two previously published very small scale maps based on much less data are a regional map (Gough and Heirtzler, 1969) and a map compiled from several tracklines running parallel to the axis of the Cayman Trough (MacDonald and Holcombe, 1978).
Map showing depth to basement in the deep-sea basins of the Pacific continental margin, Cape Mendocino to Point Conception
The U.S. Geological Survey conducted a series of cruises, EEZSCAN 84 (EEZ-SCAN 84 Scientific Staff, 1986), to collect reconnaissance data on the newly proclaimed Exclusive Economic Zone (EEZ), the area out to 200 nautical miles from the coastline of the United States. The cruises systematically surveyed the entire conterminous United States west coast EEZ using the Geological Long-Range Inclined A
