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 ...

Casey Murphy has fanned his passion for finance through years of writing about active trading, technical analysis, market commentary, exchange-traded funds (ETFs), commodities, futures, options ...

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

That scale was found to be inaccurate for very large earthquakes. The moment magnitude scale is logarithmic — that is, each whole number of magnitude represents about a 30-fold increase in ...

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 tsunami wave from an anticipated earthquake off the West Coast could reach 100 feet and permanently flood parts of the ...

The logarithmic earthquake magnitude scale used relatively high-frequency data from nearby seismograph stations, according to the USGS, but as more stations were installed around the world ...

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 ...
