There is an appropriate scale used depending on what you intend to measure in an earthquake. In the same way, you must be familiar with your own strength and potentials so that you would know how to improve and apply them in appropriate situations. In this regard, can you site some of your strengths, potentials or talents and discuss how would you use these in helping others.

Most scales are based on the amplitude of seismic waves recorded on seismometers. These scales account for the distance between the earthquake and the recording seismometer so that the calculated magnitude should be about the same no matter where it is measured. Another scale is based on the physical size of the earthquake fault and the amount of slip that occurred. Then there are also measures of earthquake shaking intensity. The intensity from one earthquake varies greatly from place to place.
What’s the difference between magnitude and intensity? This 8 minute video uses the analogy of a lightbulb to explain the how an earthquake can have different intensities at different places.
[tex]Richter Scale
The first widely-used method, the Richter scale, was developed by Charles F. Richter in 1934. It used a formula based on the amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer. That scale was specific to California earthquakes and crust; other scales, based on wave amplitudes and total earthquake duration, were developed for use in other situations and they were designed to be consistent with Richter’s scale.
The Moment Magnitude Scale
Unfortunately, many scales, such as the Richter scale, do not provide accurate estimates for large magnitude earthquakes. Today the moment magnitude scale, abbreviated MW, is preferred because it works over a wider range of earthquake sizes and is applicable globally. The moment magnitude scale is based on the total moment release of the earthquake. Moment is a product of the distance a fault moved and the force required to move it. It is derived from modeling recordings of the earthquake at multiple stations. Moment magnitude estimates are about the same as Richter magnitudes for small to large earthquakes. But only the moment magnitude scale is capable of measuring M8 (read "magnitude 8") and greater events accurately.
