In fact, the Richter scale was replaced in the ... of earthquakes occurring in southern California. The logarithmic earthquake magnitude scale used relatively high-frequency data from nearby ...

Small earthquakes, such as the 1.8-magnitude quake recorded in Somerset County, generally present little to no threat to infrastructure and the population. They serve predominantly as reminders of the ...

Magnitudes are based on a logarithmic scale (base 10). What this means is that for each whole number you go up on the magnitude scale, the amplitude of the ground motion recorded by a seismograph goes ...

Understanding Earthquake Magnitudes An earthquake’s magnitude is a measure of the energy released during the event. The Richter scale, commonly referenced in media reports, quantifies this energy on a ...
