How is the earthquake measured.
Richter Scale. Magnitude is the measure of the energy released by an earthquake. The Richter scale (M L), the first and most well-known magnitude scale, was developed by Charles F. Richter (1900-1985) at the California Institute of Technology.This was the magnitude scale used historically by early seismologists. Used by early seismologists, Richter magnitude (M L) is determined from the ...
The intensity levels I of two earthquakes measured on a seismograph can be compared by the formula log(I1I2)=M1−M2 using the common (base 10) logarithm and where M is the magnitude given by the Richter Scale. In August 2009, an earthquake of magnitude 6.1 hit Honshu, Japan.Plug magnitude values of 5.0, 6.0, and 7.0 into the equation above. The energy released by an M5 earthquake is about 2.8 x 10 12 joules. An M6 earthquake releases 7.8 x 10 13 joules, and an M7 radiates 2.1 x 10 15 joules. If you don't have a sense for what these numbers mean, the bomb dropped on Hiroshima released about 7.4 x 10 12 joules.Earthquake magnitudes are determined from seismic waves, the ground-bending waves generated by the earthquake fault. The energy in these waves lessens with distance. As you move farther from the earthquake fault, the intensity of the shaking decreases. At a fixed distance from the fault, the larger the earthquake magnitude, the greater the shaking.For example, for earthquakes measured using the original Richter scale, those that are larger than 6.5 are mischaracterized as magnitude-6.5 earthquake events. Magnitude saturation also occurs in body-wave magnitude ( m b ) and surface-wave magnitude ( M S ) calculations as earthquake magnitudes approach or exceed magnitude 8.The magnitude is mainly measured by means of seismometers, devices that measure accelerations of ground oscillations. There are a number of methods of ...

The point on the Earth's surface directly above the focus is called the earthquake …Seismic networks detect ground motion and record it as seismograms. The most reliable data comes from sensitive seismometers installed below ground. These instruments sense and measure vibrations in the earth around them and record the amplitude of those vibrations over time as the wavy or spiky lines of seismograms.

To locate an earthquake epicenter: 1. Scientists first determine the epicenter distance from three different seismographs. The longer the time between the arrival of the P-wave and S-wave, the farther away is the epicenter. So the difference in the P and S wave arrival times determines the distance between the epicenter and a seismometer.
The precision to which tilt can be measured is less than 1 part per billion (i.e. less than 1 inch in 16,000 miles). For crustal monitoring applications, these instruments are mostly installed in boreholes to avoid spurious ground tilts produced by differential thermal expansion in near-surface materials, rainfall and pumping effects.
