Magnitude scales, like the moment magnitude, measure the size of the earthquake at its source. An earthquake has one magnitude. The magnitude does not depend on where the measurement is made. Often, several slightly different magnitudes are reported for an earthquake. This happens because the relation between the seismic measurements and …For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.

The seismic zone map is revised with only four zones, instead of five. Erstwhile Zone I has been merged to Zone 11.Hence, Zone I does not appear in the new zoning; only Zones II, 111,IV and V do. The values of seismic zone factors have been changed; these now reflect more realistic values ofBoth 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.
