A massive earthquake off the coast of Kamchatka, Russia has triggered a series of tsunami alerts for Hawaii, Alaska, and the ...

April 18, 1906: The San Francisco earthquake and fire was a 7.8 on the Richter scale. Feb. 9, 1971 – Sylmar Earthquake measured 6.6 on the Richter scale Jan 17, 1994 – Northridge Earthquake 6.7 ...

(WHTM) — April 26 is the birthday of Seismologist Charles Richter, co-creator with Beno Gutenberg of the Richter Scale, which measures the intensity of earthquakes. In the early 1930s, the fi… ...

It is measured on a scale from under one to 10. Here is what the scale looks like: < 2.0: Micro (Micro earthquakes, not felt) 2.0-2.9: Minor (Generally not felt, but recorded) 3.0-3.9: Minor ...

Richter didn’t invent the scale alone. He had a partner, Beno Gutenberg, who collaborated on the measuring formula while they were professors at the California Institute of Technology.

In fact, 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 Even though it’s outdated, the term is still used often when discussing earthquakes.

The scale was developed by Charles Richter in the 1930s, but USGS says it only worked well on certain frequency and distance ranges. Newer scales were created to account for quakes outside of ...

The Richter scale was developed by seismologist Charles Richter (1900-1985) in the 1930s to bring consistent, objective criteria to evaluating the size of earthquakes.

The moment magnitude scale — which replaced the Richter scale in the 1970s — measures an earthquake’s energy by analyzing the waves it produces at various locations. This system, which the U ...
