Earthquake Magnitude scales can be thought of as a measure of the total energy ...The scale rates the intensity of an earthquake based on human reactions, natural objects and man-made structures. The scale ranges between 1 and 12, with 1 denoting that nothing was felt and 12 being total destruction. Since the scale relies more on witness reports, it is considered less scientific than the Richter Scale.Magnitude. A familiar analogy to help understand earthquake size metrics is to think about a light bulb. One measure of the strength of a light bulb is how much energy it uses. A 100-watt bulb is brighter than a 50-watt bulb, but not nearly as bright as a 250-watt bulb. The wattage of a bulb tells you about the strength of the light source. 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 ofEarthquake resistance tends to be low for structures built up to 1981, and high for those built since 1982. However, to maintain a certain range of earthquake resistance according to differences in structure and wall arrangement, resistance is not necessarily determined only by foundation age.
