Quiet geomagnetic field representation for all days and latitudes Quiet geomagnetic field representation for all days and latitudes
This paper describes a technique for obtaining the quiet-time geomagnetic field variation expected for all days of the year and distribution of latitudes from a limited set of selected quiet days within a year at a discrete set of locations. We used a data set of observatories operated by Indian and USSR scientists in 1976 and 1977 near 75°E longitude as illustration. Our method relies...

Fault growth and acoustic emissions in confined granite Fault growth and acoustic emissions in confined granite
The failure process in a brittle granite was studied by using acoustic emission techniques to obtain three dimensional locations of the microfracturing events. During a creep experiment the nucleation of faulting coincided with the onset of tertiary creep, but the development of the fault could not be followed because the failure occurred catastrophically. A technique has been developed...

The Loma Prieta, California, earthquake of October, 17, 1989: Marina District The Loma Prieta, California, earthquake of October, 17, 1989: Marina District
During the earthquake, a total land area of about 4,300 km2 was shaken with seismic intensities that can cause significant damage to structures. The area of the Marina District of San Francisco is only 4.0 km2--less than 0.1 percent of the area most strongly affected by the earthquake--but its significance with respect to engineering, seismology, and planning far outstrips its proportion...

Sedimentology, behavior, and hazards of debris flows at Mount Rainier, Washington Sedimentology, behavior, and hazards of debris flows at Mount Rainier, Washington
Mount Rainier is potentially the most dangerous volcano in the Cascade Range because of its great height, frequent earthquakes, active hydrothermal system, and extensive glacier mantle. Many debris flows and their distal phases have inundated areas far from the volcano during postglacial time. Two types of debris flows, cohesive and noncohesive, have radically different behavior that...
