Detailed explanation-1: -The Modified Mercalli Intensity Scale . The effect of an earthquake on the Earth’s surface is called the intensity.
Detailed explanation-2: -Seismology is the scientific study of earthquakes and related phenomena, such as volcanic eruptions. Earthquakes occur when the tectonic plates that make up the Earth’s crust shift and release energy in the form of waves.
Detailed explanation-3: -The intensity of an earthquake at a location is a number that characterizes the severity of ground shaking at that location by considering the effects ofthe shaking on people, on manmade structures, and on the landscape.
Detailed explanation-4: -A seismograph is the primary earthquake measuring instrument. The seismograph produces a digital graphic recording of the ground motion caused by the seismic waves. The digital recording is called a seismogram. A network of worldwide seismographs detects and measures the strength and duration of the earthquake’s waves.
Detailed explanation-5: -Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location. Intensity is determined by its effects on people, human structures, and the natural environment.
