Approximately 1,500 earthquakes are recorded in Japan every year. The magnitude of each earthquake varies, and larger earthquakes between 4 and 7 on the Richter scale regularly occur.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.Caltech's Charles Richter conceptualized magnitude. He developed a method to numerically report the relative sizes of earthquakes before earthquake magnitude could be measured directly.

The scale below is given as an instructive tool, to give a general idea of how the magnitude scale works. The scale below is intended to be roughly visual; the human eye's (dark-adapted) detection efficiency peaks around 495 nanometers, while the formal photoelectric V peak (a filtered band intended to be close to visual) is around 550 nm; CCDs tend to peak around 700 nm.

Magnitude is a dimensionless number — no physical units — that is derived from a formula involving a logarithm, which makes the scale exponential rather than linear. The difference between 6.1 and 7.1, therefore, is not ... essay stepsasme digital library Magnitude is a measurement of the size of an earthquake. Intensity is the measurement of the actual strength of the earthquake. Magnitude is measured using a seismograph. Intensity is calculated from the perceived damage caused by the earthquake. The magnitude is represented as a single number on the Richter scale.6.1 - 6.9.
