Red values indicate the earthquakes occurred in Alaska.
Blue values indicate the earthquakes occurred in California.

As more and more seismographs are installed in the world, more earthquakes can be and have been located. However, the number of large earthquakes (magnitude 6.0 and greater) have stayed relatively constant.
