The orientation and motion of these events are represented on so-called “beachball plots.” (10[2])The intensity and number of clusters of these events follow a (10[1])logarithmic law partially named for (10[1])Beno Gutenberg. (10[1])A (-5[1])“shadow zone” (10[2])where these events (10[3])cannot (10[3])be detected (10[3])is caused (10[1])by P wave refraction. (10[15])These (10[1])events (10[6])result (10[3])from (10[1])the release of built-up (10[1])strain (10[3])per (10[1])elastic (10[2])rebound (10[1])theory. (10[2])States like Oklahoma (10[2])have seen an increased rate (10[1])of liquefaction (10[1])caused by these events from fluid (10[1])injection (-5[1])used in fracking. (10[1])These events’ strength is measured with the moment (10[1])magnitude (10[1])scale. (10[2])For 10 points, what geologic (10[1])events occur at faults and have their strength reported with the Richter scale? (10[1])■END■
