Progress report on flood magnitude and frequency of Vermont streams
Carl G. Johnson, Gary D. Tasker
1974, Open-File Report 74-130
A technique is presented for estimating the magnitude and frequency of floods on streams in Vermont with drainage areas between 0.27 and 1,040 square miles. Multiple-regression techniques are used to define the relation between flood peaks, collected at a network of gaging stations maintained by the U.S. Geological Survey, and...
Hydrologic data for Little Elm Creek, Trinity River Basin, Texas, 1972
B.B. Hampton
1974, Report
The U.S. Soil Conservation Service is actively engaged in the installation of flood- and soil-erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found a...
Hydrologic data for Pin Oak Creek, Trinity River Basin, Texas, 1972
B.B. Hampton
1974, Report
The U.S. Soil Conservation Service is actively engaged in the installation of flood- and soil-erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended.

Earthquake history of Montana
C. A. von Hake
1974, Earthquake Information Bulletin (USGS) (6) 30-35
Montana is one of the most seismically active States in the Union. Since 1925, the State has experienced five shocks that reached intensity VIII or greater (Modified Mercalli Scale). During the same interval hundreds of less severe tremors were felt within the State. Montana's earthquake activity is concentrated mostly in...
Comparative toxicity of two Iodophors to rainbow trout eggs
Donald F. Amend
1974, Transactions of the American Fisheries Society (103) 73-78
Toxicity of Wescodyne(R) and Betadine(R) to eyed eggs was not adversely affected by water hardness (as calcium and magnesium) or by exposure periods up to 60 min. Both iodophors were much more toxic below pH 6.0 than at pH 8.0. In general Wescodyne was slightly more toxic than Betadine. Significant egg loss...
Computer systems for automatic earthquake detection
S.W. Stewart
1974, Earthquake Information Bulletin (USGS) (6) 17-21
U.S Geological Survey seismologists in Menlo park, California, are utilizing the speed, reliability, and efficiency of minicomputers to monitor seismograph stations and to automatically detect earthquakes. An earthquake detection computer system, believed to be the only one of its kind in operation, automatically reports about 90 percent of all local...
Scientists probe Earth’s secrets at the Hawaiian Volcano Observatory
J. D. Unger
1974, Earthquake Information Bulletin (USGS) (6) 3-11
The Hawaiian Volcano Observatory (HVO) sits on the edge of Kilauea Caldera at the summit of Kilauea Volcao, one of the five volcanoes on the island of Hawaii, the largest island in the Hawaiian Islands chain. Of the five, only Kilauea and Mauna Loa have been active in the past...
Earthquake history of Nevada
C. A. von Hake
1974, Earthquake Information Bulletin (USGS) (6) 26-29
Since 1852, more than 30 shocks of intensity VI or greater (Modified Mercalli scale) have occurred in western Nevada. At least three of these were classified as intensity X. In addition, seven earthquakes (intensity VI or greater) were centered in the eastern part of the State. Almost 2,000 other shocks...
Earthquake history of Nebraska
C. A. von Hake
1974, Earthquake Information Bulletin (USGS) (6) 32-33
Nebraska is in a region of moderate seismicity occasionally punctuated by rather strong earthquakes. Most of the State is seismic risk zone 1, with a small part in the southeast corner in risk zone 2. the first significant earthquake felt in Nebraska occurred in 1867, the year that statehood was...
Earthquake history of Missouri
C. A. von Hake
1974, Earthquake Information Bulletin (USGS) (6) 24-26
Most of Missouri's earthquake activity has been concentrated in the southeast corner of the State, which lies within the New Madrid seismic zone. As recently as Merch 29, 1972, the region was jolted by a magnitude 3.7 shock that was felt over a 168,000 square kilometre area including parts of...
Earthquake history of Mississippi
C. A. von Hake
1974, Earthquake Information Bulletin (USGS) (6) 20-21
Since its admission into the Union in 1817, Mississippi has had only four earthquakes of intensity V or greater within its borders. Although the number of earthquakes known to have been centered within Mississippi's boundaries is small, the State has been affected by numerous shocks located in neighboring States. In...
