Figure 2-3 – Earthquake Risk in Hawaii – This map from the U.S. Department of the Interior – <br />U.S. Geological Survey shows earthquake risk is greatest for Hawaii County, and specifically the <br />southeast portion of the island that includes Kapoho. The colors express the peak horizontal <br />acceleration as a percent of gravity for events with a 10% probability of exceedance in 50 years. <br /> 2.6 Lava Risk <br />That the Kapoho area is subject to lava risk is illustrated by Figure 2-4, which <br />shows the area of study and the boundaries of the 1960 lava flow. In the Puna <br />district, lava has destroyed housing in numerous areas including Kapoho, the Royal <br />Gardens Subdivision, Kalapana Village, Kalapana Gardens, and Kapaahu. The lava, <br />earthquake activity and subsidence are all related to the east rift zone of Kilauea. <br />Lava is a risk that should be planned for and the Hawaii Volcano Observatory is a <br />good source of information for this hazard. <br /> It is instructive that after many homeowners were displaced due to the <br />destruction of their homes by lava, the State was involved in providing options for <br />relocation. A similar solution could be developed for the Kapoho area given the <br />proper guidelines are provided. This however, was outside the scope of this report, <br />but is recommended that there be follow up on this issue. <br />15 <br /> <br />
