About Richter Scale Day

When is Richter Scale Day? This holiday is always celebrated on April 26

If you are a little shaky or are experiencing tremors, that’s because today is Richter Scale Day. This April 26 holiday celebrates the birth of the inventor of the Richter Scale. Born on April 26, 1900, American seismologist Charles F. Richter (1900–1985) invented the Richter Scale in 1935.

Earthquakes have been shaking the earth since the dawn of time. They are the result of the movement of the tectonic plates deep underneath the earth. When these plates move or slip along each other, they create immense energy and shock wakes resulting in surface earthquakes and tsunamis. Large earthquakes result in tremendous loss of lives and property.

The Richter Scale measures the amount of energy released by an earthquake by measuring the magnitude or seismic waves produced by an earthquake. The Richter Scale measures range from 0 to 9. On the scale, each increase in number represents an earthquake 10 times more powerful. At 4.5 an earthquake can damage buildings and structures. At 7 on the Richter scale, severe and catastrophic damage can occur.
