Landslides from the February 4, 1976, Guatemala earthquake
Edwin L. Harp, Raymond C. Wilson, Gerald F. Wieczorek
1981, Professional Paper 1204-A
The M (Richter magnitude) = 7.5 Guatemala earthquake of February 4, 1976, generated more than 10,000 landslides throughout an area of approximately 16,000 km2. These landslides caused hundreds of fatalities as well as extensive property damage. Landslides disrupted both highways and the railroad system and thus severely hindered early rescue...

Deformation of host rocks and flow of magma during growth of minette dikes and breccia-bearing intrusions near Ship Rock, New Mexico
Paul T. Delaney, David D. Pollard
1981, Professional Paper 1202
We have studied a small group of minette dikes and plugs that crop out within a flat-lying sequence of siltstone and shale near Ship Rock, a prominent volcanic throat of tuff breccia in northwestern New Mexico. Seven dikes form a radial pattern about Ship Rock we describe in detail the...

Results of a reconnaissance water-quality sampling program of the Ogallala aquifer in Colorado, Kansas, Nebraska, Oklahoma, South Dakota, and Texas
Gerald L. Feder, Noel C. Krothe
1981, Water-Resources Investigations Report 81-65
Results of a reconnaissance water-quality sampling program of the Ogallala aquifer indicates the water generally is suitable for most uses. Fluoride and selenium were the only chemical constituents found to exceed the National Interim Primary Drinking Water Regulations in water from some of the wells.Unusually large silica concentrations in many...
Hydrologic studies of the U.S. Geological Survey in major coal-resource areas of Utah through 1980
Gregory C. Lines
1981, Open-File Report 81-216
Increased interest in coal has created greater interest in water, both for environmental and water-supply reasons. This report summarizes hydrologic studies conducted in and near the major coal fields of Utah (fig. 1) by the U.S. Geological Survey through 1980. It is intended as a reference for those people dealing...

A model for simulation of flow in singular and interconnected channels
Raymond W. Schaffranek, R.A. Baltzer, D.E. Goldberg
1981, Techniques of Water-Resources Investigations 07-C3
A one-dimensional numerical model is presented for simulating the unsteady flow in singular riverine or estuarine reaches and in networks of reaches composed of interconnected channels. The model is both general and flexible in that it can be used to simulate a wide range of flow conditions for various channel...

1981, Open-File Report 81-195
The pattern-recognition technique of Bongard and others (1966), Gelfand and others (1976), and Briggs and others (1977) was modified and applied in Southeastern United States to try to detect combinations or interactions of geologic, geophysical, and topographic parameters characteristic of areas with moderate and large earthquakes. The modification involved replacing...
