Richter Scale Day - April 26th

Every year, on April 26, Richter Scale Day is celebrated. This day honors the birth of the inventor of the Richter scale, Charles P. Richter (April 26, 1900 - September 30, 1985).
Richter was an American seismologist and physicist famous for inventing the Richter scale, the scale that quantifies the magnitude of earthquakes. While working at the California Institute of Technology, along with Beno Gutenberg, Richter first used his scale in 1935.
After the Richter scale was published in 1935, it immediately became the standard measure of earthquake strength. There are now more modern methods of measuring the magnitude of earthquakes, but the intensity index is still referred to by the public as the Richter scale.

10 most powerful earthquakes ever recorded:
