My 4^th stop is at Chile, which is a convergent zone. Since 1973 there have been around 13 earthquakes of great magnitude (7.0 or over). This causes mountains and a trench on the border.  The most recent earthquake was 21.7 miles under the surface, shallow, especially for a subduction earthquake. It was a magnitude of 8.8 and very devastating. The lat/long of santiago chile is 30 degrees north north, 70 degrees west.
