Hydrology of the North Cascades region, Washington: 2. A proposed hydrometeorological streamflow prediction method
Wendell V. Tangborn, Lowell A. Rasmussen
1976, Water Resources Research (12) 203-216
On the basis of a linear relationship between winter (October-April) precipitation and annual runoff from a drainage basin (Rasmussen and Tangborn, 1976) a physically reasonable model for predicting summer (May-September) streamflow from drainages in the North Cascades region was developed. This hydrometeorological prediction method relates streamflow for a season beginning...

Hydrology of the North Cascades region, Washington: 1. Runoff, precipitation, and storage characteristics
Lowell A. Rasmussen, Wendell V. Tangborn
1976, Water Resources Research (12) 187-202
The time and space distributions of measured precipitation and measured runoff and of spring storage, which is approximately equal to the subsequent summer runoff of snowmelt and stored groundwater, have been analyzed for the North Cascades region of Washington. Neither precipitation nor runoff shows a consistent relationship with altitude, chiefly...

1976, Hydrologic Atlas 565
The failure of the Teton Dam caused extreme flooding along the Teton River, Henrys Fork, and Snake River in southeastern Idaho on June 5-8, 1976. No flooding occurred downstream from American Falls Reservoir. The inundated areas and maximum water-surface elevations are shown in a series of 17 hydrologic atlases. The...
How did the 1906 San Francisco earthquake occur?
W. Thatcher
1976, Earthquake Information Bulletin (USGS) (8) 8-13
The 1906 earthquake in San Francisco was of magnitude 8.3 and was the most destructive in the history of the United States. Because this part of California is now much more heavily populated, intense studies have been made of the 1906 earthquake in an effort to understand how it occurred...
The zonal distribution of selected elements above the Kalamazoo porphyry copper deposit, San Manuel district, Pinal County, Arizona
M.A. Chaffee
1976, Journal of Geochemical Exploration (5) 145-165
There may be many as-yet-undiscovered porphyry copper deposits that exist as blind deposits deep within exposed rock bodies. The Kalamazoo porphyry copper-molybdenum deposit is a blind deposit present at depths up to at least 1,000 m (about 3,200 ft) that contains zoning features common to many of the known...
Monitoring Mount Baker Volcano
S. D. Malone, D. Frank
1976, Earthquake Information Bulletin (USGS) (8) 21-25
Hisotrically active volcanoes in the conterminous United States are restricted to the Cascade Range and extend to the Cascade Range and extend from Mount Baker near the Canadian border to Lassen Peak in northern California. Since 1800 A.D, most eruptive activity has been on a relatively small scale and has...
Earthquake history of Rhode Island
C. A. von Hake
1976, Earthquake Information Bulletin (USGS) (8) 31-32

Earthquakes, November-December 1975
W. J. Person
1976, Earthquake Information Bulletin (USGS) (8) 26-29
There were three significant earthquakes during the last 2 months of the year. Two major earthquakes, both magnitude 7.2 occurred, bringing the final major earthquake total for the year to 13, somewhat below the annual average which is about 18. One great earthquake (8.0 and above) per year is average....
A revised “earthquake report” questionnaire

1976, Seismological Research Letters (8) 18-22
The revised “Earthquake Report” questionnaire introduced here is designed to restrict the replies on the effects of earthquakes as closely as possible to a set of effects that can be evaluated by use of a computer program. Differences in intensity resulting from evaluation by different individuals using their own qualitative...
Earthquake history of Oregon
C. A. von Hake
1976, Earthquake Information Bulletin (USGS) (8) 30-33
Although situated between two States (California and Washington) that have has many violent earthquakes, Oregon is noticeably less active seismically. the greatest damage experienced resulted from a major shock near Olympia, Wash., in 1949. During the short history record available (since 1841), 34 earthquakes of intensity V, Modified Mercalli Scale,...

Interactive computer programs for petrologic modeling with extended Q-mode factor analysis
A.T. Miesch
1976, Computers & Geosciences (2) 439-492
An extended form of Q-mode factor analysis may be used if the row-sums of the data matrix are constant and can be helpful especially in developing and testing petrologic-mixing models for igneous systems. The first step is to represent the sample compositions as unit vectors in M-dimensional space and then...
