Both data sets must be converted to the same units. Seismic is collected in time (ms) whereas sonic logs are collected in depth (m of ft.). Using check shot data, either the seismic or sonic logs can be converted. Once the units are converted, a wavelet extraction can take place in order to produce the synthetic seismogram.The China seismic intensity scale (CSIS) is a national standard in the People's Republic of China used to measure seismic intensity.Similar to EMS-92 on which CSIS drew reference, seismic impacts are classified into 12 degrees of intensity, or liedu (Chinese: 烈度; pinyin: lièdù, literally "degrees of violence") in Roman numerals from I for insensible to XII for landscape reshaping.Earthquake - Magnitude, Seismology, Epicenter: Earthquake magnitude is a measure of the “size,” or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs.

Richter magnitudes The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake). The original formula is: [6]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.Mercalli intensity scale. The Mercalli intensity scale (or more precisely the Modified Mercalli intensity scale) is a scale to measure the intensity of earthquakes. Unlike with the Richter scale, the Mercalli scale does not take into account energy of an earthquake directly. Rather, they classify earthquakes by the effects they have (and the ...6.1 - 6.9.
