A direct method for calculating instrument noise levels in side-by-side seismometer evaluations A direct method for calculating instrument noise levels in side-by-side seismometer evaluations
The subject of determining the inherent system noise levels present in modem broadband closed loop seismic sensors has been an evolving topic ever since closed loop systems became available. Closed loop systems are unique in that the system noise can not be determined via a blocked mass test as in older conventional open loop seismic sensors. Instead, most investigators have resorted to...

IRIS/USGS plans for upgrading the Global Seismograph Network IRIS/USGS plans for upgrading the Global Seismograph Network
This report has been prepared to provide information to organizations that may be asked to participate in a program to upgrade the global seismographic network. In most cases, the organizations that will be offered new instrumentation by the U.S. Geological Survey currently operate stations in the World-Wide Standardized Seismograph Network (WWSSN) or the Global Digital Seismograph...

Structures associated with strike-slip faults that bound landslide elements Structures associated with strike-slip faults that bound landslide elements
Large landslides are bounded on their flanks and on elements within the landslides by structures analogous to strike-slip faults. We observed the formation of thwse strike-slip faults and associated structures at two large landslides in central Utah during 1983-1985. The strike-slip faults in landslides are nearly vertical but locally may dip a few degrees toward or away from the moving...

Morphology of sea-floor landslides on Horizon Guyot: application of steady-state geotechnical analysis Morphology of sea-floor landslides on Horizon Guyot: application of steady-state geotechnical analysis
Mass movement and erosion have been identified on the pelagic sediment cap of Horizon Guyot, a seamount in the Mid-Pacific Mountains. Trends in the size, shape and preservation of bedforms and sediment textural trends on the pelagic cap indicate that bottom-current-generated sediment transport direction is upslope. Slumping of the sediment cap occurred on and that the net bedload...
