Use it …The Mercalli Intensity Scale is only useful for measuring earthquakes in inhabited areas and is not considered particularly scientific, as the experiences of witnesses may vary and the damage caused may not accurately reflect an earthquake’s strength. It is, however, used to compare the damage caused by earthquakes in different areas.Earthquake - Seismic Waves, Properties, Geology: At all distances from the focus, mechanical properties of the rocks, such as incompressibility, rigidity, and density, play a role in the speed with which the waves travel and the shape and duration of the wave trains. The layering of the rocks and the physical properties of surface soil also affect wave …a more uniform measure of the strength of an earthquake. The seismic moment of an earthquake is determined by the strength or resistance of rocks to faulting (shear modulus) multiplied by the area (length times width) of the fault that ruptures and by the average displacement that occurs across the fault during the earthquake. The seismicEarthquake Dimensions - Rupture Size and Offset. Another measure of earthquake size is the area of the fault that slipped during the earthquake. During large earthquakes the part of the fault that ruptures may be hundreds of kilometers long and 10s of kilometers deep. Smaller earthquake rupture smaller portions of the fault.The scale used to measure the strength of an earthquake is called the Richter scale.

Soil liquefaction occurs when the effective stress (shear strength) of soil is reduced to essentially zero.This may be initiated by either monotonic …Most earthquakes occur along the boundaries between the Earth’s tectonic plates. The crust of the Earth is divided into plates. When a plate collides with or slides past another plate, this causes earthquakes.The Richter Magnitude scale is one such scale that you have likely heard of. Figure 6.2. 1: Seismogram. One issue with measuring earthquakes is that as the waves propagate, the energy is spread out over more area. Figure 6.2. 2: Distance from Source. As E A r e a ↓, the amplitude decreases with distance.An earthquake measuring 5.0, for example, possesses shaking amplitude ten times more intense than that of an earthquake which measures 4.0 at the same distance. Magnitudes on the scale are expressed in both whole numbers and decimals. ... and the occurring damage may not reflect the strength of an earthquake accurately.Enter the two magnitudes you want to compare – for our example, these are 5.8 and 7.1. We find out that a magnitude of 7.1 is 20 times bigger (on a seismogram, in terms of amplitudes) and ~89 times stronger (in terms of energy release) than a 5.8 magnitude. Remember that for each unit increase in magnitude:As per the given scenario, => P = R* (10^n) where P is the greater magnitude. R is the lesser magnitude. 10^n is no. of times the greater magnitude is stronger than the lesser magnitude. On solving we will get R = 2, n=3, we will get P =5. Hence B. gmatclubot.
