Watch the earthquake on the firefly map

This map shows 203,186 earthquakes of magnitude 4.0 or more that occurred between 1898 and 2003. Each match was marked by a firefly with increasing brightness proportional to the intensity.

Looking at the map, it can be seen that the pathway connecting the locations of the earthquakes is faint, winding and splitting the oceans on the earth. The earthquake along the spillway centers tend to be lighter. The most well-studied spindle center, called the Peak of the Atlantic, divides the Atlantic Ocean, to the right of the map.

Pacific earthquake runs across the eastern edge of the Pacific Ocean, cutting off a wide line off South America. Another spreading center runs through the Indian Ocean and pulls onto the Red Sea.

Subduction zones, where the stratigraphic plates overlap, cause one floor to sink below the other and sink into the mantle of the earth - the process that produces the greatest earthquakes in history - now On the map as a strip of light in a busy American city.

The author of the map is John Nelson, the company's manager representing IDV Solutions.

The map has helped to systematize all of the earthquakes that have occurred over the past century. These data are not new, but are presented in a compelling way, which can be a useful tool for teaching, researching and monitoring.
