Atomic clocks and our computer networks are the new, far superior form of time measurement, but we’re forcing them to keep in sync with this older form of measurement,” remarks Dr. David Gozzard, an ...

An earthquake with a magnitude of 4.4 on the Richter Scale hit Jhajjar, Haryana, and was felt across Delhi and the NCR.

A U.S. district judge in San Francisco had temporarily blocked large-scale federal layoffs known as "reductions in force." ...

Magnitude is measured using a machine called a seismometer which produces a seismograph, and the Richter scale indicates how powerful the quake is on a scale of 1-10.

Magnitude is measured using a machine called a seismometer which produces a seismograph, and the Richter scale indicates how powerful the quake is on a scale of 1-10.

While the Richter Scale is widely recognized, modern seismologists prefer the moment magnitude scale for accurate measurement of earthquakes.

But the Richter scale was eventually scrapped in favor of what is known as the moment magnitude scale. The moment magnitude scale measures the movement of rock along the fault and accurately ...

Both quakes exceeded 2.5 on the moment magnitude scale, which measures the strength of an earthquake. Anything less than 2.5 is generally not felt, but people may notice at least a tremor or find ...

The moment magnitude scale, as it is known, replaced one developed by an American seismologist, Charles Richter, that was used until the 1970s.

A string of earthquakes shook just south of the border Sunday and early Monday, with the largest measured at 4.9, according to the U.S. Geological Survey.

The Richter scale was replaced in the 1970s by other magnitude scales that are more accurate. Even though it’s outdated, the term is still used often when discussing earthquakes.
