Probability of Future Events <br />Wr1 <br />32 <br />26 <br />Chapter Three <br />The United State Geological Survey's (USGS) PSHA models shown in Figure 6.5 gives the <br />probability of an earthquake with a magnitude equal to or greater than 4.75 occuring in the next <br />50 years to be between 10% and 20 %. The probability increases to the north where more <br />seismic activity has been recorded and projected. However, this region is most at risk from a <br />very large, distant earthquake that might occur in Oklahoma or the Missouri - Tennesee areas <br />that would have an MMI in this area of VI or greater. This type of earthquake has a probability <br />of occurring once per 500 years. <br />135 <br />16 August 1931 <br />_ 1 -.0 t <br />J- L_1-44 <br />I- ,• <br />�-� <br />%y_-4_ -) <br />111 lift 1 _31V% 1 <br />-4 <br />9 <br />Q® 104 101) 98 <br />Source: www.ig.utexas.edu <br />5.
