(NaturalNews) An animated earthquake map video produced by the U.S. NWS Pacific Tsunami Warning Center (PTWC) shows every recorded earthquake between January 1, 2001, and December 31, 2015, – the first 15 years of the 21st century.

The amazing and somewhat terrifying animation proceeds at a rate of 30 days per second, and reveals a great deal of constant activity around the globe – particularly along major fault lines located where tectonic plates collide, such as those of the Pacific "Ring of Fire."

From the YouTube description of the video:

"The earthquake hypocenters first appear as flashes then remain as colored circles before shrinking with time so as not to obscure subsequent earthquakes. The size of the circle represents the earthquake magnitude while the color represents its depth within the earth."
