1985, Earthquake Information Bulletin (USGS) (17) 44-49
The Costa Rican volacno Rincon de la Vieja is loosely but mysteriously translated as the "Old Lady's Corner." It consists of six volcanic centers that form a remote elongated ridge standing some 1300m above the surrounding terraine. Geologically speaking, the Guanacaste province of northern Costa Rica consists of a series...
Reducing losses from earthquakes through personal preparedness
W. J. Kockelman
1985, Earthquake Information Bulletin (USGS) (17) 50-59
Actions to reduce earthquake hazards can be divided into five phases:two occur before the event, one during the event, and two after the event. The phases are: (1) Mitigation techniques taken anywhere from 1 to 20 years before the event, (2) preparedness measures taken 1 to 20 weeks before the...

Diversion of lava during the 1983 eruption of Mount Etna
J. P. Lockwood, R. Romano
1985, Earthquake Information Bulletin (USGS) (17) 124-133
Mankind's first known attempt to divert a lava flow was in 1669, when a flow from Mount Etna volcano threatened the Sicilian city of Catania. This attempt was largely unsuccessful, in part due to opposition by citizens of another town, Paterno. Attempts to divert lava flows from Mauna Loa Volcano...

In 1883, the brilliant geologist G. K. Gilbert wrote an article for the Salt Lake Tribune, "A theory of earthquakes of the Great Basin," which began: There are many geologists who are very wise, but even they do not understand the forces which produce mountains. And yet it must be admitted,...

In the United States, Wyoming experienced a couple of moderate earthquakes, and off the coast of northern California, a strong earthquake shook much of...
An interview with Karl Steinbrugge
H. Spall
1985, Earthquake Information Bulletin (USGS) (17) 134-147
For thirty years the name of Karl V. Steinbrugge has been synonymous with the Insurance Services Office in San Francisco. There he was in charge of their earthquake engineering and research activities for the United States, and his work included detailed engineering investigations of the probable earthquake damage to structures as...

Kinds of damage that could result from a great earthquake in the central United States
M. G. Hooper, S. T. Algermissen
1985, Earthquake Information Bulletin (USGS) (17) 84-97
In the winter of 1811-12 a series of three great earthquakes occurred in the New Madrid, Missouri seismic zone in the central United States. In addition to the three principal shocks, at least 15 other earthquakes of intensity VIII or more occurred within a year of the first large earthquake...

Foraging recruitment by the Giant Tropical Ant Paraponera clavata (Hymenoptera, Formicidae)
Bruce A. Barrett, Clive D. Jorgenson, Sandra J. Looman
1985, Pan-Pacific Entomologist (61) 334-338
Increased foraging of an exceptionally abundant, but ephemeral, food source by ants can result from foraging excitement that does not include pheromone trails, tandem running, or from recruitment of other workers along pheromone trails (Carrol and Janzen, 1973). They also provided rationale for two types of short-lived pheromone trails resulting...
YELLOWSTONE MAGMATIC-HYDROTHERMAL SYSTEM, U. S. A.
R.O. Fournier, A.D. Pitt
Stone Claudia, editor(s)
1985, Conference Paper
At Yellowstone National Park, the deep permeability and fluid circulation are probably controlled and maintained by repeated brittle fracture of rocks in response to local and regional stress. Focal depths of earthquakes beneath the Yellowstone caldera suggest that the transition from brittle fracture to quasi-plastic flow takes place at about...
Comparison of digestion methods for total elemental analysis of peat and separation of its organic and inorganic components
C. S.E. Papp, T. F. Harms
1985, The Analyst (110) 237-242
In order to find the most efficient digestion method for the total elemental recovery in peat, ten samples were subjected to different techniques and analysed for Ca, Mg, Fe, AI, Na, K, Mn, P, Zn, Cu, Li, Cd, Co, Ni, Pb and Si using atomic-absorption spectrophotometry. The most satisfactory procedures...
Summary of data on the age of the Orca Group, Alaska: A section in The United States Geological Survey in Alaska: Accomplishments during 1984

1985, Circular 967
The Orca Group is a widespread, thick, complexly deformed accretionary sequence of flysch and tholeiitic basalt in the Prince William Sound area (Winkler, 1976; Winkler and Plafker, 1981) (fig. 49). Despite a number of extensive field studies of the Orca Group, reliable data on the age of the unit have...
Removal of iron interferences by solvent extraction for geochemical analysis by atomic-absorption spectrophotometry
L. Zhou, T. T. Chao, R. F. Sanzolone
1985, Talanta (32) 475-478
Iron is a common interferent in the determination of many elements in geochemical samples. Two approaches for its removal have been taken. The first involves removal of iron by extraction with methyl isobutyl ketone (MIBK) from hydrochloric acid medium, leaving the analytes in the aqueous phase. The second consists of...
Trace element content of gossans at four mines in the West Shasta massive sulfide district
R. F. Sanzolone, J. A. Domenico
1985, Economic Geology (80) 2206-2212
We evaluated the trace element content of gossans at four mines in the West Shasta Cu-Zn mining district in California. We found little difference in trace element content between the chipped rock rind and whole-rock gossan samples. Gossans derived from disseminated sulfides were found to have a lower trace element...
