Hazards of geomagnetic storms Hazards of geomagnetic storms
Geomagnetic storms are large and sometimes rapid fluctuations in the Earth's magnetic field that are related to disturbances on the Sun's surface. Although it is not widely recognized, these transient magnetic disturbances can be a significant hazard to people and property. Many of us know that the intensity of the auroral lights increases during magnetic storms, but few people realize...

Evaluation of models proposed for the 1991 revision of the International Geomagnetic Reference Field Evaluation of models proposed for the 1991 revision of the International Geomagnetic Reference Field
The 1991 revision of the International Geomagnetic Reference Field (IGRF) comprises a definitive main-field model for 1985.0, amain-field model for 1990.0, and a forecast secular-variation model for the period 1990-1995. The five 1985.0 main-field models and five 1990.0 main-field models that were proposed have been evaluated by comparing them with one another, with magnetic observatory...

Lava-flow characterization at Pisgah Volcanic Field, California, with multiparameter imaging radar Lava-flow characterization at Pisgah Volcanic Field, California, with multiparameter imaging radar
Multi-incidence-angle (in the 25° to 55° range) radar data acquired by the NASA/JPL Airborne Synthetic Aperture Radar (AIRSAR) at three wavelengths simultaneously and displayed at three polarizations are examined for their utility in characterizing lava flows at Pisgah volcanic field, California. Pisgah lava flows were erupted in three phases; flow textures consist of hummocky pahoehoe...

An evaluation of installation methods for STS-1 seismometers An evaluation of installation methods for STS-1 seismometers
This report documents the results of a series of experiments conducted by the authors at the Albuquerque Seismological Laboratory (ASl) during the spring and summer of 1991; the object of these experiments was to obtain and document quantitative performance comparisons of three methods of installing STS-1 seismometers. Historically, ASL has installed STS-1 sensors by cementing their...

The Loma Prieta, California, Earthquake of October 17, 1989: Strong ground motion and ground failure The Loma Prieta, California, Earthquake of October 17, 1989: Strong ground motion and ground failure
Professional Paper 1551 describes the effects at the land surface caused by the Loma Prieta earthquake. These effects: include the pattern and characteristics of strong ground shaking, liquefaction of both floodplain deposits along the Pajaro and Salinas Rivers in the Monterey Bay region and sandy artificial fills along the margins of San Francisco Bay, landslides in the epicentral...
