Pedimentation versus debris-flow origin of plateau-side desert terraces in southern Utah Pedimentation versus debris-flow origin of plateau-side desert terraces in southern Utah

Plateau-side terraces in arid areas around the world are commonly described as pediment remnants, although, in many cases, they may have been formed by debris-flow deposition. Pediments do exist in the area of the Aquarius and Kaiparowits Plateaus of southern Utah; however, many alluvial terraces that were classified by previous workers as pediments are actually formed of thick deposits...

Geomagnetic paleointensities from excursion sequences in lavas on Oahu, Hawaii Geomagnetic paleointensities from excursion sequences in lavas on Oahu, Hawaii

Paleomagnetic data demonstrating three late Tertiary excursions in the direction of the geomagnetic field recorded in sequences of basaltic lavas on the island of Oahu, Hawaii were published by R. R. Doell and G. B. Dalrymple in 1973. We have determined geomagnetic paleointensities by the Thelliers' method for 14 lavas from the three sites. During these experiments, considerable...

A new event detector designed for the Seismic Research Observatories A new event detector designed for the Seismic Research Observatories

A new short-period event detector has been implemented on the Seismic Research Observatories. For each signal detected, a printed output gives estimates of the time of onset of the signal, direction of the first break, quality of onset, period and maximum amplitude of the signal, and an estimate of the variability of the background noise. On the SRO system, the new algorithm runs ~2.5x...
