...A. Pitts Abstract The recent landslipping in the Lyme Regis area has, as Mr Conway indicates, related to reactivation of reconstituted and ‘brecciated’ Lias (Lias Head) and Upper Greensand (Cretaceous Head) (Conway, this issue). This is exemplified by the current slippage of East Cliff...

..., Borrego Mountain, and Imperial Valley earthquakes. Those measurements may have begun too late to resolve power-law behavior at early times. If current logarithmic behavior of the Superstition Hills fault persists, right-lateral slippage will approach 90 cm 10 yr after the rupture. Changes in the along...

...ROBERT P SHARP Abstract Vigorous attack is currently being made on glacier flow by field studies, laboratory investigations, and theoretical analyses. Knowledge of the physical properties and behavior of ice deep within glaciers remains unsatisfactory, because laboratory experiments do...

...Ali Afsharpoor; Farzam Javadpour; Jinqiao Wu; Lucy T. Ko; Quansheng Liang Abstract The pore geometry and slip conditions are two principal characteristics of liquid flow in shale noncircular nanopores. We have considered the pore shape and liquid slippage on the pore interior wall in pore-network...

The current study describes the geometric (aggregate thickness, orientation, and porosity) and elastic properties...

.... Although history records no large earthquakes resulting from slippage along at least the principal segment of the fault in China, youthful landforms and disruptions of young sedimentary rocks indicate that it has generated large earthquakes during the Pleistocene and Holocene epochs. The historic...

...W. L. Chenoweth ABSTRACT Slippage in demand, increasing costs, and low spot market prices continued to influence the uranium industry during 1982. The supply of uranium exceeds the current demand and, as a result, exploration for uranium declined in the United States for the fourth straight year...

.... Rapid burial in the deltas preserved stream-transported organic matter and related nutrients. The sediments also were enriched by abundant marine organic matter concentrated in the delta area by prevailing winds and ocean currents. Abundant raw materials and reducing conditions necessary...

...Bruce A. Bolt; Walter C. Marion abstract A differential transformer has been used as a displacementmeter across a crack in a culvert under the Memorial Stadium, UC Berkeley. The crack is believed to be the result of progressive right-lateral slippage in recent years along the Hayward fault which...

... that for the more important larger-diameter pipe. The second drawback with the purely empirical fragility relation is the lack of a basic understanding of the influence of obvious parameters. For example, the influence of burial depth, if any, is not provided by any of the currently available empirical...

We argue that similar pore-pressure triggering of fault slip in the crust may occur because of the accumulation of gas columns...

... or lateral translation was observed at the downstream toe. The major upstream slippage occurred longitudinally along the full length of the maximum height channel section of the dam, with a length of approximately 85 m along the dam axis. In addition, relatively minor longitudinal cracking occurred along...

... that the bend is not an original course but is a subsequent dent. Since resistance to horizontal slippage increases with the slightest deviation from a straight line, the rift would tend to take a relatively straight course at the start, as is evident from its long, straight stretches, and any subsequent bends...

Whitten and Claire: Resurveys over monumented points established near the winery also yield a rate of slippage or creep along the fault line of one-half inch per year...

.... Similar creep, or slippage, has continued since the earthquakes. Extensive nets of survey markers installed by 30 June across the active fault trace had recorded slippage as great as 0.1 inch per day by 12 July. The fault trace associated with the earthquakes is principally in alluvium of unknown depth...

... that strain is necessarily accumulating in all of these areas. Even in areas of demonstrated regional shearing, the relative importance of elastic strain accumulation versus fault slippage is unknown, although slippage is clearly not taking place everywhere along major “active” faults of the region...
