Figure 11.2.2 11.2. 2 provides a closer look at magnitude (M) 4 and larger earthquakes in an area of divergent boundaries in the mid-Atlantic region near the equator. Here, as we saw in Chapter 10, the segments of the mid-Atlantic ridge are offset by some long transform faults.

The Richter scale [1] ( / ˈrɪktər / ), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg-Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". [3]How much bigger is a magnitude 8.7 earthquake than a magnitude 5.8 earthquake? An explanation of the magnitude of an earthquake versus the strength, or energy release, of an earthquake... with a little bit of math. The earthquake hypocenter was at a depth of 10.0 km (6 mi) according to USGS and 5 km (3 mi) according to KOERI. The shock had a focal mechanism corresponding to strike-slip faulting.
