File Description [top]

GeoRef, the database of the American Geosciences Institute (AGI), covers worldwide technical literature on geology and geophysics. GeoRef corresponds to the print publications: Bibliography and Index of North American Geology, Bibliography of Theses in Geology, and the Geophysical Abstracts, Bibliography and Index of Geology Exclusive of North America. GeoRef organizes and indexes papers from more than 13,000 serials and other publications representative of the interests of the 50 professional geological and earth science societies that are members of the AGI.

GeoRef is international in coverage with about 40% of the indexed publications originating in the United States and the remainder from outside the U.S. Publications of international organizations represent about 7% of the file. The database includes current coverage of more than 3,500 journals as well as books and book chapters, conference papers, government publications, theses, dissertations, reports, maps, and meeting papers.

  /AB  ABSTRACT: Regional rockfall events in the Sierra Nevada of California 
     are caused by distant earthquakes on the northern and southern San 
     Andreas fault as well as by local earthquakes. Lichenometric dating 
     of synchronous pulses of rockfalls that are presumed to be caused by 
     five historical earthquakes suggests an accuracy of 2.2-3.5 yr (95% 
     confidence level) for dating young events. Comparison of lichenometric 
     ages for prehistorical rockfalls with precise radiocarbon ages of 
     surface-rupture times at the Pallett Creek and Wrightwood 
     palesoseismology sites indicates that earthquakes on the southern San 
     Andreas fault caused rockfalls 200 to 400 km to the north. A major 
     rockfall event at about ALDL 1690 supports the Fumal et al. (1993) 
     model for a San Andreas fault earthquake that was not detected at 
     Pallett Creek. The A.D. 1690 event in the chronology indicates that 
     the earthquake recurrence interval was shorter and that the degree of 
     clustering of times of earthquakes was less on the Mojave segment of 
  LN=, N1=, N2=,   the San Andreas fault than previously thought.
