Magnitude is the most commonly used measure ...We find the intensity, I, when we have R = 8.3 . We do this by isolating I in the equation and then plugging in the value of R and I 0 = 1.The earthquake struck at a shallow depth of 6.7 miles from the surface, according to the USGS. The intensity of shaking during an earthquake diminishes as the depth increases. That's why the 4.8-magnitude earthquake that hit California at a depth of 19.2 miles Monday had a lower impact.Magnitude. A familiar analogy to help understand earthquake size metrics is to think about a light bulb. One measure of the strength of a light bulb is how much energy it uses. A 100-watt bulb is brighter than a 50-watt bulb, but not nearly as bright as a 250-watt bulb. The wattage of a bulb tells you about the strength of the light source.ANNUAL EARTHQUAKES. In a single year, on average, more than 900,000 earthquakes are recorded and 150,000 of them are strong enough to be felt. Each year about 18 earthquakes are major with a Richter magnitude of 7.0 to 7.9, and on average one earthquake has a magnitude of 8 to 8.9. Magnitude 9 earthquakes are rare. The Intensity Prediction Equation (IPE) is an estimate of intensity for a given earthquake magnitude and distance.
