The Loma Prieta, California, Earthquake of October 17, 1989: Strong ground motion The Loma Prieta, California, Earthquake of October 17, 1989: Strong ground motion
Strong ground motion generated by the Loma Prieta, Calif., earthquake (MS~7.1) of October 17, 1989, resulted in at least 63 deaths, more than 3,757 injuries, and damage estimated to exceed $5.9 billion. Strong ground motion severely damaged critical lifelines (freeway overpasses, bridges, and pipelines), caused severe damage to poorly constructed buildings, and induced a significant...

Measurements of heat and mass flow from thermal areas in Lassen Volcanic National Park, California, 1984-93 Measurements of heat and mass flow from thermal areas in Lassen Volcanic National Park, California, 1984-93
Rates of heat loss from eight steam-heated thermal areas and one conductively heated thermal area in Lassen Volcanic National Park have been determined from measurements made during the period 1984-93. Total heat discharge at the steam-heated areas is assumed proportional to the rate of steam upflow from underlying reservoirs. The dominant mode of heat loss differs among the areas...

Stability of submerged slopes on the flanks of the Hawaiian Islands, a simplified approach Stability of submerged slopes on the flanks of the Hawaiian Islands, a simplified approach
Undersea transmission lines and shoreline AC-DC conversion stations and near-shore transmission lines are being considered as part of a system for transporting energy between the Hawaiian Islands. These facilities will need to be designed so that they will not be damaged or destroyed by coastal or undersea landslides. Advanced site surveys and engineering design of these facilities will...

Chemistry of spring and well waters on Kilauea Volcano, Hawaii, and vicinity Chemistry of spring and well waters on Kilauea Volcano, Hawaii, and vicinity
Published and new data for chemical and isotopic samples from wells and springs on Kilauea Volcano and vicinity are presented. These data are used to understand processes that determine the chemistry of dilute meteoric water, mixtures with sea water, and thermal water. Data for well and spring samples of non-thermal water indicate that mixing with sea water and dissolution of rock from...

210Pb balance and implications for particle transport on the continental shelf, U.S. Middle Atlantic Bight 210Pb balance and implications for particle transport on the continental shelf, U.S. Middle Atlantic Bight
Supply of 210Pb to the continental shelf off the northeastern United States is dominated by the deposition from the atmosphere, the rate of which is reliably known from previously published work. Excess 210Pb inventories in the shelf sediments show accumulations that are nearly in balance with the supply, even in areas of relict sands where it is believed that no net accumulation of...

A compilation of sulfur dioxide and carbon dioxide emission-rate data from Mount St. Helens during 1980-88 A compilation of sulfur dioxide and carbon dioxide emission-rate data from Mount St. Helens during 1980-88
Airborne monitoring of Mount St. Helens by the USGS began inMay 1980 for sulfur dioxide emissions and in July 1980 forcarbon dioxide emissions. A correlation spectrometer, orCOSPEC, was used to measure sulfur dioxide in Mount St.Helens' plume. The upward-looking COSPEC was mounted in afixed-wing aircraft and flown below and at right angles to theplume. Typically, three to six traverses...
