Richter Scale Day
Date When Celebrated : This special day is always observed on April 26
If you are a little shaky or are experiencing tremors, that's because today is Richter Scale Day.
Richter Scale Day celebrates the birth of the inventor of the Richter Scale. Born on April 26, 1900, American seismologist Charles F. Richter (19001985) invented the Richter Scale in 1935.
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 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.
