Chapter 7:Hazard Analysis-Earthquakes <br /> • Develop a seismic risk profile for the port infrastructure system inventory. <br /> • Allocate hazard mitigation program funding in compliance with eligibility <br /> requirements for FEMA assistance. <br /> 7.3 Probability of Occurrence <br /> Earthquake recurrence intervals have been estimated by Klein (1994) and Wyss Koyanagi <br /> (USGS Bulletin 2006, 1992) and range from 3 to 4.5 years for "large" earthquakes with <br /> magnitudes greater than 5.5; 29 to 44 years for"major" earthquakes with magnitudes greater <br /> than 7; and, 120 to 180 years for "great" earthquakes approaching a magnitude of 8. Figure <br /> 7-10 provides a visual distribution and magnitude of recent and historic earthquakes. <br /> 1EG" YS8° ia6° <br /> 22. <br /> Kauai Oahu <br /> 'diil•a.i <br /> Honolulu <br /> ��yYlo.lo+kr'&•i <br /> Lanai <br /> KahLi u z-,-,L! <br /> Hawaii <br /> U F.L.na K.-..i - <br /> 1925 <br /> H Iq <br /> 175-. 19$3 <br /> Norrh Pacific Ocean 95 <br /> -1051 <br /> 1964 �t 9ti9 <br /> 1 H66 <br /> C 3` tC0 ]Ixa u,xtws <br /> EXPLANATION <br /> 15 Qd 2006 r1�alt.aene a.<rat .. k.y s.e <br /> Eart*uakes1876-2U65 rear M" Dey Time Lac L-nj leaq <br /> M 0.3.99 yxRe 0.5 �§ 6a.5 ls. -z55.i a.0. <br /> 1689 p0.
