This movie shows earthquakes in the Caribbean region larger than Magnitude 3.5 (about 8,000 events), in the years between Jan. 1, 2008 – Dec. 31, 2014. The Magnitude 7.0 Haiti earthquake was on January 12, 2010. This movie covers same time window and distance in latitude (but not longitude) as the movie on the Japan region and Tohoku Mag9.0 earthquake: vimeo.com/153547571.
The dot size is (non-linearly) proportional to magnitude and the color is proportional to depth according to these rules:
