Partial abstract: "Recent advances in the fields of remote sensing, engineering geology, seismology, and earthquake engineering have developed a need for a systematic comprehensive review of the basic principles and methods of applying remote sensing for evaluation of earthquake hazards and seismic risk. This paper responds to this need by reviewing basic concepts, summarizing essential, state-of-the-art knowledge of theory and instrumental methods, establishing procedures evaluations, and discussing representative case histories that illustrate earthquake hazard evaluations that are based on remote sensing analysis.

Seismic volcanic risk assessment, Puna geothermal prospect area, Hawaii

Prepared for Thermal Power Company, Dillingham, AMFAC"This report summarizes the geologic, volcanologic, and seismologic data that relate to evaluation of the Seismic-Volcanic Risk Assessment (SVRA) for the Puna Geothermal Prospect (PGP) of the Lower East Rift Zone (LERZ) on the volcano, Kilauea, Hawaii. The basis for the assessment sections is developed in detail in the Geology Section (3.0), with the volcanic and seismic assessments discussed in Sections 4.0 and 5.0, respectively. The Volcanic Risk Assessment leads to conclusions that the hazards and risk from volcanic activity and associated fissuring and faulting are high and diverse, but the risk to engineered structures and installations can be mitigated by proper procedures in siting and design. Recommendations are made as to the methods and factors that should be considered for mitigation. The Seismic Risk Assessment demonstrates that the hazard and risk from ground motion is of three general sources: frequent low magnitude volcanic earthquakes with epicenters near the site, infrequent earthquakes of deep focus, low to moderate magnitudes and generally from Kilauea, and tectonic earthquakes of about 6.5 to 7.2 magnitude from the Hilina fault zone with epicenters at distances of from 20 to 50 km (12 to 30 mi)."2 maps : black and whiteMaps: Plate 1 / Epicenter map of earthquakes of ML>4.0 from 1960 to 1980 with focal depths greater than about 25 km. -- Plate 2 / Epicenter map of earthquakes of of ML>4.0 from 1929 to 1980 with focal depths less than about 25 km.Thermal Power Compan
