One of the most commonly known earthquake-measuring tools is the Richter Scale, but the system is no longer used today. The Richter scale was replaced in the 1970s by other magnitude scales that ...

Scientists largely use the moment magnitude scale to categorize earthquakes’ strength and size in a way that’s more accurate than the long-used Richter ... a kind of graph called a seismogram.

This month, the UK has been rocked by two earthquakes in Norfolk and Essex, measuring 3.7 and 2.6 on the Richter scale respectively. While Britain is not prone to extreme tremors, seismologists ...

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 Richter scale was found to be inaccurate for very large earthquakes. The moment magnitude scale can be hard for nonexperts to decipher. It is logarithmic, meaning that each whole number of ...

Swift literally rocked Lisbon, with the star's show in the city registering on the Richter scale ... earthquake, which ended up being dubbed the "Swift Quake." The noise and dancing at one of the ...

Charles Richter. 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 ...
