Round 7: Tossup 15

These events are represented with black and white circular diagrams nicknamed "beach balls." Plots of these events are used to create diagrams of Wadati-Benioff zones. (15[2])A location-dependent (15[2])scale of the intensity of these events is named for Mercalli. (15[1])The liquidity of the outer core was determined from the lack of a phenomena produced by these events. In (*) subduction zones, these events’ underground hypocenters may lie deep below their above ground epicenters. These events are measured by the Moment Magnitude scale, which has largely replaced the Richter scale. For 10 points, what events often caused by faults cause the ground to shake? ■END■
