(AP) -- Sunday's earthquake in Sumatra had a preliminary magnitude of 9.0, classifying it as a great quake and making it the strongest in 40 years. Earthquakes near the very top of the magnitude scale are difficult for scientists to measure. For one thing, they occur rarely - once a year or less - so researchers don't have many chances to analyze them. And, the tools that scientists use to measure movements in the planet's crust are becoming more sophisticated. So the way in which they...

The Richter scale assigns a single number to quantify the amount of seismic energy released by an earthquake. The scale uses a base-10 logarithm by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a particular type of seismometer. A earthquake measuring 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. The moment magnitude, calibrated to give generally similar value for medium-sized...
