What’s the difference between magnitude and intensity? This 8 minute video uses the analogy of a lightbulb to explain the how an earthquake can have different intensities at different places.

the moment magnitude scale offers consistency across all sizes and types of quakes. Still, the Richter Scale remains widely recognized by the public. It introduced the concept of a logarithmic ...

Use precise geolocation data and actively scan device characteristics for identification. This is done to store and access ...

The moment magnitude scale can be hard for nonexperts to decipher. It is logarithmic, meaning that each whole number of magnitude represents about a 32-fold increase in the amount of energy ...

The readings are communicated in terms of magnitude, and the intensity, based on the effects on people and structures, is communicated with the Modified Mercalli (MM) Intensity Scale. Here's a ...

How the strength of quakes is measured has changed over the years, so you'll see references to the Richter Scale, earthquake magnitude and intensity. Here's a quick primer on what they mean and ...

the USGS forecasts about a 23% chance of East Tennessee experiencing a magnitude 3 or higher aftershock in the next week. "BUT remember that the scale is logarithmic, so a 3.0 is TEN TIMES weaker ...
