Difference Between Earthquake Magnitude and Intensity

Intensity: The severity of earthquake shaking is assessed using a descriptive scale – the Modified Mercalli Intensity Scale. Magnitude: Earthquake size is a quantitative measure of the size of the earthquake at its source. The Richter Magnitude Scale measures the amount of seismic energy released by an earthquake.

What makes the difference between intensity and magnitude?

Magnitude is a measure of earthquake size and remains unchanged with distance from the earthquake. Intensity, however, describes the degree of shaking caused by an earthquake at a given place and decreases with distance from the earthquake epicentre.

What is the difference between earthquake magnitude and intensity quizlet?

What is the difference between an intensity scale and a magnitude scale? An intensity scale measures that physical damage done by an earthquake. A magnitude scale measures the energy that the seismic waves send out. ... They both are both open ended and they both measure energy sent out by seismic waves.

How do you find the magnitude and intensity of an earthquake?

The Richter scale defines the magnitude of an earthquake to be R=log(IcIn) where Ic is the intensity of the earthquake and In is the intensity of a standard earthquake. Therefore, you can write the difference of two magnitudes as R2−R1=log(I2I1).

What is intensity of earthquake?

The intensity is a number (written as a Roman numeral) describing the severity of an earthquake in terms of its effects on the earth's surface and on humans and their structures. ... There are many intensities for an earthquake, depending on where you are, unlike the magnitude, which is one number for each earthquake.

Which is stronger magnitude or intensity?

Magnitude and Intensity measure different characteristics of earthquakes. 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.

What is the strongest intensity scale?

PHIVOLCS Earthquake Intensity Scale (PEIS)

What is magnitude example?

Magnitude is defined as large in size or very important. An example of magnitude is the depth of the Grand Canyon. An example of magnitude is the size of the problem of world hunger. A measure of the amount of energy released by an earthquake, as indicated on the Richter scale.

What is the highest intensity of earthquake?

What does a 5.0 magnitude earthquake feel like?

5.0 - Unmistakable as an earthquake, this can rattle dishes, break windows, and rock cars. Poorly constructed buildings are at high risk of structural damage. 6.0 - You can still stand up, but your books and pictures may fall off the shelves and walls. Your furniture may move and your walls may crack.

Is a 4.0 earthquake bad?

A magnitude 4.0 eastern U.S. earthquake typically can be felt at many places as far as 60 miles from where it occurred, and it infrequently causes damage near its source. A magnitude 5.5 eastern U.S. earthquake usually can be felt as far as 300 miles from where it occurred, and sometimes causes damage out to 25 miles.

How do you read earthquake magnitude?

Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.

What does each magnitude earthquake feel like?

A small earthquake nearby will feel like a small sharp jolt followed by a few stronger sharp shakes that pass quickly. A small earthquake far away will probably not be felt at all, but if you do feel it, it will be a subtle gentle shake or two that is easier to feel if you're still and sitting down.
