"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)."
