> An earthquake that measures a 6.0 on the Richter scale would be how muchstronger than one that measures as a 3.0?And the answer: 1,000 times as strong. Photo courtesy: Discovery News.Because of the logarithmic basis of the Richterscale, each whole number increase on the scale represents a tenfold increase inpower. So an earthquake that measures at 6.0 on the Richter scale would be 10times as strong as one that measures at 5.0. It would also be 100,000 times asstrong as one that measures 1.0 on the scale.The Richter scale, developed by (you guessed it) Charles Richter, has been theprimary scale for measuring earthquakes since its creation in the 1930s. Unlikeother previously-used earthquake scales, the Richter scale works with"magnitude" to determine the strength of any given earthquake. In thissituation, magnitude reflects how much the Earth's crust shifts during anearthquake. The magnitude of an earthquake is determined by the Richter's logarithmic code.The seismograph – the instrument that detects the earthquake – records theamplitude of waves, which translate into the energy released by the earthquake.In today's science, the Richter scale is often used alongside other measurementscales such as the Mercalli Scale to gather more information about theexperience and severity of any given earthquake. In any given year, millions of earthquakes occur that are too weak to be noticedor recorded. The National Earthquake Information Center estimates around 20,000earthquakes per year are strong enough to be recorded, yet almost 80% of thosequakes occur along the rim of the Pacific Ocean called the "Ring of Fire" (checkout this [https://www.askqotd.com/pacific-ring-of-fire/] past AskQOTD article to learnmore about this fiery ring.)Did you know?An earthquake under the ocean can cause a tsunami in which waves of water traveloutward in all directions. The waves can even reach speeds up to 600 miles perhour (the speed of a jet!).
