Spring sapping on the lower continental slope, offshore New Jersey
James M. Robb
1984, Geology (12) 278-282
Undersea discharge of ground water during periods of lower sea level may have eroded valleys on part of the lower continental slope, offshore New Jersey. Steep-headed basins, cliffed and terraced walls, and irregular courses of these valleys may have been produced by sapping of exposed near-horizontal Tertiary strata. Joints in...
Magnetic properties of the Bay of Islands ophiolite suite and implications for the magnetization of oceanic crust
B. Ann Swift, H. Paul Johnson
1984, Journal of Geophysical Research B: Solid Earth (89) 3291-3308
Rock magnetic properties, opaque mineralogy, and degree of metamorphism were determined for 101 unoriented samples from the North Arm and Blow-Me-Down massifs of the Bay of Islands ophiolite complex, Newfoundland. The weathered and metamorphosed extrusive basalt samples have a weak, secondary magnetization arising from oxidation and exsolution of ilmenite of...
On the front lines in Coalinga
G. Marcussen
1984, Earthquake Information Bulletin (USGS) (16) 188-189
I have often been asked, "As a city manager, what is the first thing you do in an earthquake?" I generally say, "Look up, something heavy might be falling on you. Actually, the first step is to declare an emergency. The city council can ratify it later. The declaration is in...
Jesuits in seismology
D. Linehan
1984, Earthquake Information Bulletin (USGS) (16) 156-165
Jesuits have been involved with scientific endeavors since the 16th century, although their association with seismology is more recent. What impelled Jesuit priests to also become seismologists is am matter of conjecture. Certainly the migration of missionaries to various parts of the world must have resulted in queries to their...
The “anomalous cedar trees” of Lake Ashi, Hakone Volcano, Japan
Y. Oki
1984, Earthquake Information Bulletin (USGS) (16) 24-27
On the bottom of Lake Ashi at Hakone, Japan, there stand great trees that, since ancient times, have been widely known as the "Anomalous Cedar Trees" of Ashi. It is not known why these trees grow on the bottom of the lake, and it remains one of the mysteries of...
Earthquakes; September-October 1983

Alaska seismic studies
J. Rogers
1984, Earthquake Information Bulletin (USGS) (16) 28-33
Seismic monitoring in Alaska by the U.S Geological Survey consists of a network of 46 stations focused on the following four areas: Yakatut Bay to Prince William Sound, centered on the Yakatage seismic gap. Anchorage, and the surrounding region of rapid growth and development.  The active Cook Inlet volcanoes-Iliamna,Redoubt and Spurr. (Two of...
Likelihood of volcanic eruption at Long Valley, California, is reduced
D. Kelly
1984, Earthquake Information Bulletin (USGS) (16) 191-192
A relatively low level of earthquake activity as well as reduced rates of ground deformation over the past year have led U.S Geological Survey scientists to conclude that the likelihood of imminent volcanic activity at Long Valley, California, is reduced from that of mid-1982 through 1983....
Eyewitness account of the 1931 great earthquake at Hawke’s Bay, New Zealand
H. Spall
1984, Earthquake Information Bulletin (USGS) (16) 12-20
No part of New Zealand is far from a known earthquake origin. The magnitude 7.9 earthquake of 1931 at Hawke's Bay, North Island, on February 3, 1931, was the most serious event recorded in New Zealand hsitory. It was responsible for 256 deaths. The Modified Mercalli intensity reached XI in...

G. Wendt
1984, Earthquake Information Bulletin (USGS) (16) 23-23
The October 7 earthquake near Blue Mountain Lake in the central Adirondack Mountains registered a preliminary Richter magnitude of 5.2. It was widely felt throughout the Northeastern United States and Canada and occurred in an area that has been periodically shaken by earthquakes throughout recorded history. Since 1737, at least...
Stalking the next Parkfield earthquake in Central California
R. A. Kerr
1984, Earthquake Information Bulletin (USGS) (16) 215-224
Looking southeast from Middle Mountain toward Gold Hill, it is a subtle furrow in the grassy knolls of the Cholame Valley of California's Coast Range. To geophysicists, this 19-mile section of the San Andreas fault midway between San Francisco and Los Angeles is the most well understood, most intensely monitored...
Old seismographs still in operation in Northern California
E. McCormick
1984, Earthquake Information Bulletin (USGS) (16) 194-195
Felt earthquakes are frequent on the Cape Mendocino end of the northern San Andreas fault in Humboldt County, California. For this reason a Bosch-Omori seismograph was installed by Horace Winslow of the U.S Coast and Geodetic Survey in teh old city jail in Ferndale as early as 1932. In 1981...
