Two of the most common methods used to measure earthquakes are the Richter scale and the moment magnitude scale. The Mercalli scale also measures the effects of an earthquake at different locations.Groundwater levels in wells can oscillate up and down when seismic waves pass. The water level might remain higher or lower for a period of time after the seismic waves end, but sometimes a long-term offset of groundwater levels follows an earthquake. The largest recorded earthquake-induced offset in a well is a one meter rise.Charles F. Richter devised his magnitude scale in the mid-1930s while investigating earthquakes in California. He used seismographs which magnified ground motion 2800 times, and as a baseline, he defined a magnitude 0 earthquake as being one that would produce a record with an amplitude of one-thousandth of a millimeter at a …Earthquake magnitude levels scale meter vector / Richter / disaster Hi-Tech Digital Sound Wave Low and Hight richter scale with Circle Vibration on Black Background,technology and earthquake wave concept,design for music studio and science,Vector Illustration.

In this case, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake, and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake. Intensity scales date from the late 19th and early 20th centuries, before seismographs capable of accurate measurement of ground motion were developed.

Counts toward Master of Disaster badge. Category Earth + Atmospheric Sciences Best for High School + Middle School.In 1898 the scale was changed to a numerical scheme, assigning earthquakes levels 0–7. In 1908, descriptive parameters were defined for each level on the scale, and the intensities at particular locales accompanying an earthquake were assigned a level according to perceived effect on people at each observation site. Earthquake - Magnitude, Intensity, Effects: The violence of seismic shaking varies considerably over a single affected area. Because the entire range of observed effects is not capable of simple quantitative definition, the strength of the shaking is commonly estimated by reference to intensity scales that describe the effects in qualitative terms. Intensity scales date from the late 19th and ... Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept.
