- Intensity tells us how much damage was done: buildings crushed, human lives lost, and so on. Intensity and magnitude can be very different. That’s because an earthquake of small magnitude can do a lot of damage in a region that isn’t prepared—and vice versa. Intensity is measured by the Modified Mercalli Intensity Scale.

May 6, 2024 · An earthquake is an intense shaking of Earth’s surface. The shaking is caused by movements in Earth’s outermost layer. Why Do Earthquakes Happen? Although the Earth looks like a pretty solid place from the surface, it’s actually extremely active just below the surface.
The Modified Mercalli Intensity Scale is commonly used to determine the amount of destruction caused by an earthquake. It defines 12 levels of earthquake strength. The Richter Magnitude Scale is based upon the amount of energy released by the rock movements.
from Earthquakes. 750L - 890L. When you hear about an earthquake, you usually hear about its magnitude, or strength, on the Richter scale. But there’s another way to measure an earthquake. Intensity tells us how much damage was done: buildings crushed, human lives lost, and so on. Intensity and magnitude can be very different.
Feb 16, 2020 · The amount of damage an earthquake causes is measured by the Mercalli Scale, which is a measure of intensity. This changes depending on the part of the Earthquake being measured. For example damage at the epicentre of an Earthquake would be more than further away from the epicentre.
Lesson Plan (PDF) Objectives. In this lesson, you and your children will: learn about the cause of earthquakes, learn about how scientists measure earthquake intensity, build their own seismograph to measure shaking. Materials. marker or felt-tip pen. plastic or metal ruler that is flexible. tape (masking tape is best)
Furthermore, earthquake intensity, or strength, is distinct from earthquake magnitude, which is a measure of the amplitude, or size, of seismic waves as specified by a seismograph reading. See below Earthquake magnitude.
Intensity describes how strong the shaking is at a given location. In the United States and many other locations, intensity values are described with Roman numerals from I (barely perceptible) to X (widespread destruction), using the Modified Mercalli Intensity scale. This definition of intensity requires a subjective judgment by an observer.
