Intensity not magnitude measures how about the earthquake is a location. Most common measurement of intensity is a modified Mercalli scale. Mercalli scale. Modified Mercalli is a good qualitative description of intensity in terms of damage levels.Foreshocks are earthquakes that precede larger earthquakes in the same location. An earthquake cannot be identified as a foreshock until after a larger earthquake in the same area occurs. Aftershocks are smaller earthquakes that occur in the same general area during the days to years following a larger event or "mainshock."The magnitude of earthquake is determined from measurements on seismographs, whereas the intensity is determined from effects on people, human structures, and the natural environment. Table 1 presents the difference between magnitude and intensity of earthquake. The Richter scale is a base-10 logarithmic scale, meaning that each order of magnitude is 10 times more intensive than the last one. In other words, a two is 10 times more intense than a one and a three is 100 times greater. In the case of the Richter scale, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake ...There is a big difference between an earthquake's size and how strong it is. Damage from an earthquake with a large magnitude is less likely than damage from a smaller magnitude earthquake. There should be a strategy for earthquake mitigation that takes into account both the size and severity of the danger.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.Earthquake 8.4 intensity is 251188643. 10^3.7=I/I0. 5011=I/I0.

The Richter scale [1] ( / ˈrɪktər / ), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". [3]Intensity is another way to measure the importance of an earthquake. If the magnitude of a certain earthquake is only one, the intensity can change from place to place, according to what has happened to things and people; generally, the further away from the epicenter, the more it decreases. The intensity of an earthquake establishes In fact ... Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake.These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location. Magnitudes are usually determined from measurements of an earthquake's seismic waves as recorded on a seismogram.The magnitude scale is really measuring the physical size of the earthquake, not the STRENGTH (energy) of the quakes. So, a magnitude 8.7 is 794 times bigger than a 5.8 quake as measured on seismograms, but the 8.7 quake is about 23,000 times STRONGER than the 5.8! Since it is really the energy or strength that knocks down buildings, this is ...1.The Richter scale measures the seismic activity magnitude of an earthquake and other areas that can be measured numerically. 2.The Mercalli scale measures the intensity of the earthquake. 3.The Mercalli scale is an older scale that predates the Richter scale. 4.The Richter scale is more commonly used than the Mercalli scale. The Intensity Prediction Equation (IPE) is an estimate of intensity for a given earthquake magnitude and distance. Earthquakes in different regions of the world tend to create different levels of shaking for many reasons, such as the mechanism of the earthquake, the nature of the geological environment, and the quality of infrastructure.
