A model of geomagnetic secular variation for 1980-1983 A model of geomagnetic secular variation for 1980-1983
We developed an updated model of the secular variation of the main geomagnetic field during 1980 through 1983 based on annual mean values for that interval from 148 worldwide magnetic observatories. The model consists of a series of 80 spherical harmonics, up to and including those of degree and order 8. We used it to form a proposal for the 1985 revision of the International Geomagnetic...

A detailed chronology of the most recent eruption period at Mount Hood, Oregon A detailed chronology of the most recent eruption period at Mount Hood, Oregon
The most recent eruptive period of Mount Hood volcano, the Old Maid eruptive period, was characterized by volcano-hydrologic events (hydrologic events initiated by volcanic activity) which resulted in extensive lahar inundation in the White, Sandy, and Zigzag River drainages and produced a lithic pyroclastic flow which traveled at least 9 km down the White River from the vent area at...

Reconnaissance investigation of sediment distribution, erosion, and transport in the upper Deschutes River, Deschutes County, Oregon, November 1986 Reconnaissance investigation of sediment distribution, erosion, and transport in the upper Deschutes River, Deschutes County, Oregon, November 1986
A preliminary investigation of sediment distribution, erosion, and transport in the upper Deschutes River was conducted in response to the perceived problem that brown trout spawning gravels were being rendered unusable due to an accumulation of fine-grained sediment. Contrary to the contention that channel gravels are being covered by fine-grained sediment, examination of the river...

System designed for issuing landslide alerts in the San Francisco Bay area System designed for issuing landslide alerts in the San Francisco Bay area
A system for forecasting landslides during major storms has been developed for the San Francisco Bay area by the U.S Geological Survey and was successfully tested during heavy storms in the bay area during February 1986. Based on the forecasts provided by the USGS, the National Weather Service (NWS) included landslide warnings in its regular weather forecasts or in special weather...

Recent mafic volcanism on Mars Recent mafic volcanism on Mars
The evidence for volcanism on Mars is commonly accepted, but none has been documented in the Valles Marineris equatorial rift system. A recent survey of the troughs in this valley revealed dark patches that are interpreted to be volcanic vents. The configuration and association of these patches with tectonic structures suggest that they are of internal origin; their albedo and color...

A comparison of the largest rainfall-runoff floods in the United States with those of the People's Republic of China and the world A comparison of the largest rainfall-runoff floods in the United States with those of the People's Republic of China and the world
The maximum historic rainfall-runoff floods measured in the United States, the People's Republic of China and the world all plot close to a smooth curve of drainage area versus discharge. In the United States, the possibility that flood peaks were overestimated and the closeness of these peaks to the probable maximum floods suggest that this limiting curve of maximum floods will not...
