S-waves are shear waves that move by displacing atoms perpendicular to the wave’s path. This requires “shear strength,” which only solids possess. Since the outer core is a liquid (molten iron and nickel), it has no shear strength, causing S-waves ...
Liquefaction occurs when intense shaking causes the water pressure between soil particles to increase. This causes the soil to lose its strength and act like a liquid. Buildings on such soil may tilt, sink or collapse as the foundation literally ...
An isoseismal line is a contour line on a map that connects locations experiencing the same intensity of earthquake shaking. These lines help scientists visualize the distribution of damage and the impact of local soil conditions on seismic energy. They ...
Statement (B) is incorrect because the Richter scale is a mathematical formula (a scale), not a physical instrument. The instrument used to detect and record earthquakes is the seismograph. Additionally, the Richter scale measures magnitude (energy released), while intensity (damage/shaking) ...
