Richard L. Bernknopf, David S. Brookshire, Philip T. Ganderton
2003, Professional Paper 1683
What role can geoscience information play in the assessment of risk and the value of insurance, especially for natural hazard type risks? In an earlier, related paper Ganderton and others (2000) provided subjects with relatively simple geoscience information concerning natural hazard-type risks. Their research looked at how subjects purchase insurance...

Station corrections for the Katmai Region Seismic Network
Cheryl K. Searcy
2003, Open-File Report 2003-403
Most procedures for routinely locating earthquake hypocenters within a local network are constrained to using laterally homogeneous velocity models to represent the Earth's crustal velocity structure. As a result, earthquake location errors may arise due to actual lateral variations in the Earth's velocity structure. Station corrections can be used to...
