MAJOR PAST HAZARD EVENTS <br />Presidential disaster declarations are typically issued for hazard events that cause more damage than state <br />and local governments can handle without assistance from the federal government, although no specific <br />dollar loss threshold has been established for these declarations. A presidential disaster declaration puts <br />federal recovery programs into motion to help disaster victims, businesses and public entities. Some of the <br />programs are matched by state programs. Kittitas County has experienced 11 events since 1964 for which <br />presidential disaster declarations were issued. These events are listed in Table 4-2. <br />Review of these events helps identify targets for risk reduction and ways to increase a community’s <br />capability to avoid large-scale events in the future. Still, many natural hazard events do not trigger federal <br />disaster declaration protocol but have significant impacts on their communities. These events are also <br />important to consider in establishing recurrence intervals for ha zards of concern. Seismic activity in the <br />county has been recorded from the 1930s through the present, though earthquake damage has been low. <br />Table 4-2.
