7.1 Physics 251Fig. 7.39 Cumulative probability for having earthquakes with magnitude above m (excedence).California (circles, over 10,000 earthquakes, q = 1.65, a = 5.73 × 10 −6 ), Iberian Peninsula(triangles, 3000 earthquakes, q = 1.64, a = 3.37 × 10 −6 ), and Andalusian region (squares, 300earthquakes, q = 1.60, a = 3 × 10 −5 ). For further details see [542].Fig. 7.40 Cumulative number of earthquakes with magnitude above m per year. The dots are fromthe California catalog (for further details see [545]), and correspond to 335,076 earthquakes. Theblue curve is a q-exponential with q = 2.05.
