The Richter scale measures strength while the Mercalli intensity scale measures the effects of an earthquake. Another difference between the Richter scale and the Mercalli intensity scale is _____. the Richter scale provides a single measurement while the Mercalli intensity scale can produce multiple measurements depending on the area affectedAug 4, 2020 · The level of structural seismic damage is divided into 5°, and the intensity of structural seismic damage is evaluated by virtue of the EMS-98, MSK-81, and CSIS-08 seismic intensity scales (considering that EMS-98 is the most widely used intensity scale worldwide, it is compared with MSK-81 and CSIS-08). it produces. The Richter Scale has been in use for many years and is an example of a logarithmic scale. Logarithmic scales are linear scales in ‘x’ such as 1.0, 2.0, 3.0 etc, but they represent magnitude changes of 10, 100 and 1000 etc. Because natural phenomena span such a large range in energy, logarithmic scales are often used to representBoth 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.10 sie 2018 ...
