NettetIntensity is a measured quantity that is recorded by an instrument. Magnitude by comparison is a computed value. More about the equations The basic equation for magnitude and intensity is M = log (I/S) or magnitude is the base ten logarithm of intensity over standard. Applying some algebra and rules of logarithms, Intensity can … Nettet6. mai 2024 · 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.

Examples “Luckily, that 7.8 earthquake last week was a slow burner; it built up so gradually that everybody had a chance to evacuate before it really hit.” “Some of the worst earthquakes I’ve ever experienced were slow burns over a period of a few hours.” Prior to the development of the magnitude scale, the only measure of an earthquake's strength or "size" was a subjective assessment of the intensity of shaking observed near the epicenter of the earthquake, categorized by various seismic intensity scales such as the Rossi-Forel scale.
