Large landslides, composed of megabreccia, interbedded in Miocene basin deposits, southeastern Arizona Large landslides, composed of megabreccia, interbedded in Miocene basin deposits, southeastern Arizona
The landslides in the Kearny and El Capitan Mountain quadrangles, Pinal and Gila Counties, Ariz., are tabular or lens like masses of megabreccia enclosed in Miocene basin deposits. The megabreccias within individual slide blocks are composed of pervasively brecciated Precambrian and younger formations that remain in normal stratigraphic sequence, indicating that each landslide moved as a...

Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: February 1977 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: February 1977
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory; therefore it should be regarded as preliminary.

Spectral characteristics of geomagnetic field variations at low and equatorial latitudes Spectral characteristics of geomagnetic field variations at low and equatorial latitudes
Geomagnetic field spectra from eight standard observations at geomagnetic latitudes below 30?? were studied to determine the field characteristics unique to the equatorial region. Emphasis was placed upon those variations having periods between 5 min and 4 hr for a selection of magnetically quiet, average, and active days in 1965. The power spectral density at the equator was about ten...

Landslides Landslides
Landslides are frequent in areas where there is high seismicity and steep slopes. Landslides associated with earthquakes may cause as much damage as the initial ground shaking. They may also occur long after the earthquake. Some of the major earthquakes that have occurred during the past 15 years demonstrate the hazards of seismically triggered landslides. THe Hebgen Lake, Mont...
