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) ...
The epicenter is the location on the Earth’s surface where the tremors are felt first. Since it is the point directly above the focus, the seismic waves (specifically P-waves) have the shortest distance to travel to reach this spot. Consequently, ...
The Elastic Rebound Theory explains the mechanical origin of earthquakes. It suggests that rocks on opposite sides of a fault are subjected to force and accumulate energy by deforming elastically. When the internal strength of the rocks is exceeded, they ...
