Revised age for Midway volcano, Hawaiian volcanic chain
G. B. Dalrymple, D.A. Clague, M. A. Lanphere
1977, Earth and Planetary Science Letters (37) 107-116
New conventional K-Ar,40Ar/39Ar, and petrochemical data on alkalic basalt pebbles from the basalt conglomerate overlying tholeiitic flows in the Midway drill hole show that Midway evolved past the tholeiitic shield-building stage and erupted lavas of the alkalic suite27.0 ± 0.6m.y. ago. The data also show that previously published conventional K-Ar ages...
Earthquake history of South Dakota
C. A. von Hake
1977, Earthquake Information Bulletin (USGS) (9) 35-36
Twelve earthquakes of intensity V or greater (Modified Mercalli scale) have centered within the borders of South Dakota. All the shocks were rather localized, except that of 1911 which was felt over an area of approximately 100,000 km2. Some earthquakes from neighboring States were felt strongly in South Dakota. ...
Earthquake history of Tennessee
C. A. von Hake
1977, Earthquake Information Bulletin (USGS) (9) 37-39
The western part of the State was shaken strongly by the New Madrid, Mo., earthquakes of 1811-12 and by earthquakes in 1843 and 1895. The area has also experienced minor shocks. Additional activity has occurred in the eastern part of the State, near the North Carolina border. Forty shocks of...
Earthquake research in China

1977, Earthquake Information Bulletin (USGS) (9) 18-21
On the evening of February 4, 1975, a magnitude 7.3 earthquake occurred near Haicheng in Liaoning Privince in eastern China. Almost 90 percent of the structures in Haicheng, a city of 90,000 people, were destroyed or seriously damaged. Given the time of day, the subfreezing temperatures, and the population density...
Earthquake history of Virginia
C. A. von Hake
1977, Earthquake Information Bulletin (USGS) (9) 28-30
Virginia is a State of considerable seismic activity, although the earthquakes are rarely strong. Thirty-five shocks, intensity MM V or greater (Modified Mercalli Scale), are listed with epicenters within its borders. The locations of several of the older events are not precise; thus, the above count i subject to alteration....
Evaluating the intensity of U.S. earthquakes
R. Simon, C. Stover
1977, Earthquake Information Bulletin (USGS) (9) 24-29
The intensity scale based on the Modified Mercalli Scale of 1931 (MM scale) measures the effects of seismic shaking. Intensity estimations are often the only representation of the size of an earthquake when small shocks occur in areas far removed from seismograph stations that can record them instrumentally. The impossibility...
Earthquake prediction: A perspective for a national program

1977, Earthquake Information Bulletin (USGS) (9) 10-13
Earthquake predictions is a rapidly advancing field of research and development. And now is the time to begin planning how we should use the results of this research. ...
Demographic features of a lapland longspur population near Barrow, Alaska
Thomas W. Custer, Frank A. Pitelka
1977, The Auk (94) 505-525
Breeding density, clutch size, hatching and fledging success, and survival of adult Lapland Longspurs (Calcarius lapponicus) were monitored over a 7-year period near the Naval Arctic Research Laboratory, Barrow, Alaska. Nesting begins as soon as the tundra starts to clear of snow and appears to be timed so that the...

Rising ground-water level in downtown Louisville, Kentucky, 1972-1977
J. M. Kernodle, D. V. Whitesides
1977, Water-Resources Investigations Report 77-92
Ground-water levels in the alluvial aquifer in Louisville, Jefferson County, Kentucky, are rising at a rate which could cause wet basements and possible structural damage tc buildings in the downtown area by 1982. The predicted water level for 1982 is based on the nearly linear increase which has been observed...

Classification of the hydrologic settings of lakes in the north central United States
Thomas C. Winter
1977, Water Resources Research (13) 753-767
The hydrologic settings of 150 lakes in the north central United States were investigated by principal component analysis as a first attempt to develop a general classification of the hydrologic settings of lakes. Precipitation-evaporation balance and the water quality variables have high loadings on the first principal component. Highest loadings...

Orientale and Caloris
J.F. McCauley
1977, Physics of the Earth and Planetary Interiors (15) 220-250
Applications of experimental explosion-crater data to Orientale and recent geologic mapping of the basin have produced a new stratigraphy and genetic model for Orientale that are also applicable to Caloris. The inner-basin scarp of Orientale is thought to be a bench separating the upper parts of the basin from its...
Square wave voltammetry at the dropping mercury electrode: Theory
J. H. Christie, J.A. Turner, R. A. Osteryoung
1977, Analytical Chemistry (49) 1899-1903
The theoretical aspects of square wave voltammetry at the dropping mercury electrode are presented. The technique involves scanning the entire potential range of interest on a single drop of a DME. Asymmetries in the waveform as well as variations in current measurement parameters are discussed. Indications are that previous uses...
