The 1960 Valdivia earthquake or Great Chilean Earthquake of Sunday, 22 May 1960 is to date the most powerful earthquake ever recorded in Earthâs history, rating 9.5 on the moment magnitude scale. It occurred in the afternoon and its resulting tsunami affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands in Alaska.
Quantitative measure of earthquake-strength (magnitude) that indicates the seismic energy released by an earthquake at its epicenter (measured from a distance of 100 miles) on a 1 to 10 scale. It is a logarithmic scale: an increase of 1.0 in measurement corresponds to an increase of 10 times in the magnitude. The most powerful earthquakes recorded so far had a magnitude of 8.6, and occurred in 1920 in the Gansu province of China. Developed in 1935 by the US seismologist Charles F. Richter (1900-1985) of the California Institute of technology. Earthquake-intensity is measured on the Mercalli scale. Use Richter scale in a sentence. A massive earthquake of epic proportion struck the coast of California early last Sunday morning, measuring a whopping 9.0 on the Richter Scale.
