An economic and geographic appraisal of a spatial natural hazard risk: a study of landslide mitigation rules An economic and geographic appraisal of a spatial natural hazard risk: a study of landslide mitigation rules
Efficient mitigation of natural hazards requires a spatial representation of the risk, based upon the geographic distribution of physical parameters and man-related development activities. Through such a representation, the spatial probability of landslides based upon physical science concepts is estimated for Cincinnati, Ohio. Mitigation programs designed to reduce loss from landslide...

The Manti, Utah, landslide The Manti, Utah, landslide
PART A: The Manti landslide is in Manti Canyon on the west side of the Wasatch Plateau in central Utah. In early June 1974, coincident with the melting of a snowpack, a rock slump/debris flow occurred on the south rim of Manti Canyon. Part of the slumped material mixed with meltwater and mobilized into a series of debris flows that traveled down the slope a distance of as much as 1.2 km...

Landslides triggered by earthquakes in the central Mississippi Valley, Tennessee and Kentucky Landslides triggered by earthquakes in the central Mississippi Valley, Tennessee and Kentucky
We mapped 221 large (more than 200 ft across) landslides of three morphologically distinct types on the bluffs bordering the Mississippi alluvial plain in western Tennessee and Kentucky Old coherent slides (146 landslides, or 66 percent of the total) include translational block slides and single and multiple-block rotational slumps, all of which are covered by mature vegetation and have...

New trend- trigonometric model for interpolation and prediction of the geomagnetic field utilizing the new DGRF models New trend- trigonometric model for interpolation and prediction of the geomagnetic field utilizing the new DGRF models
At the IUGG Assembly at Vancouver during August 1987 new definitive geomagnetic reference field (DGRF) models to degree 10 for 1945, 1950, 1955, and 1960 were adopted by IAGA. Before these new DGRF models were accepted, the author developed a trend and trigonometric model (old trig model) based on the models IGRF 1945, IGRF 1950, IGRF 1955, IGRF 1960, DGRF 1965, DGRF 1970, DGRF 1975...

Range indices of geomagnetic activity Range indices of geomagnetic activity
The simplest index of geomagnetic activity is the range in nT from maximum to minimum value of the field in a given time interval. The hourly range R was recommended by IAGA for use at observatories at latitudes greater than 65??, but was superceded by AE. The most used geomagnetic index K is based on the range of activity in a 3 h interval corrected for the regular daily variation. In...
