Abstract
Siting of Liquefied Natural Gas (LNG) facilities requires seismological investigations to identify the closest capable faults, to estimate the capability of faults in the vicinity of proposed sites to generate earthquakes, and to provide engineers with appropriate ground-motion parameters (peak acceleration, predominant period, and duration of strong ground-motion) for design and construction. These investigations consist of analysis of seismicity data to correlate hypocenters and faults, estimation of the maximum magnitude of an earthquake for particular faults, and calculations of recurrence intervals of earthquakes. The investigation of the proposed Little Cojo Bay LNG Terminal Site, near Point Conception, California, for which a peak acceleration of about 0.65 g appears reasonable, is presented as an example.
