Earthquake magnitudes are determined by measuring the amplitudes of seismic waves. The amplitude is the height of the wave relative to the baseline (Figure 9.13). Wave amplitude depends on the amount of energy carried by the wave. The amplitudes of seismic waves reflect the amount of energy released by earthquakes.The U. S. Geological Survey (USGS) Earthquakes Hazards Program real-time map shows the location and magnitude of recent earthquakes around the world. 9.8: Earthquake Risk Earthquake magnitude is an absolute value that measures pure energy release. Intensity, however, i.e. how much the ground shakes, is determined by several factors.

Difference between an Earthquake with intensity 7.1 and an earthquake with intensity 7.2 We all know what earthquakes are and what they can do. Recently, there have been many natural disasters in various parts of the world including Tsunamis, hurricanes etc. but earthquakes remain on top of the list with regards to the number of occurrences and the amount of damage they can do. Comparison between measurements on the Modified Mercalli scale and magnitudes on the moment magnitude scale. Earthquakes can be measured in two ways. One method is based on magnitude—the amount of energy released at the earthquake source. The other is based on intensity—how much the ground shakes at a specific location.The Richter scale determines the magnitude of the earthquake in question by measuring its seismic waves. While the Richter scale is logarithmic, the Mercalli scale is linear. The measuring tool used in a Richter scale is a seismograph while observation is used on the Mercalli scale.

The Mercalli Scale is based on observable earthquake damage. From a scientific standpoint, the magnitude scale is based on seismic records while the Mercalli is based on observable data which can be subjective. Thus, the magnitude scale is considered scientifically more objective and therefore more accurate.Key Takeaways. Richter Scale measures the magnitude of an earthquake, while Mercalli Scale measures the intensity of an earthquake at a specific location. Richter Scale is calculated based on the seismic waves generated by an earthquake, while the effects of an earthquake on people, structures, and the environment determine Mercalli Scale.Earthquake magnitude is an absolute value that measures pure energy release. Intensity however, i.e. how much the ground shakes, is a determined by several factors. Earthquake Magnitude—In general, the larger the magnitude, the stronger the shaking and the longer the shaking will last.On the Richter scale, the Alaska quake was "bigger" having a M S of 8.6 compared to the M S of the Chilean quake of 8.5. However, in measuring the seismic moment, the Chilean quake was larger, giving M w of 9.5 versus the M w of 9.2 for the Alaskan earthquake. The reason is that the Chilean earthquake released more energy, but in the Alaskan ...1 What's the difference between magnitude & intensity? Magnitude: energy released by an earthquake.

Hope it help you.To avoid this mistake, it is important to understand the difference between magnitude and intensity and to use the correct term when discussing earthquakes or other natural disasters. Using The Terms Interchangeably. Another common mistake is using the terms magnitude and intensity interchangeably. The epicenter is where they all intersect. This is called earthquake_______. Measures Magnitude. The Richter Scale; The Moment Magnitude Scale. Measures Intensity. The Modified Mercalli scale. Study with Quizlet and memorize flashcards containing terms like Seismograph, Epicenter, Focus and more.Jan 11, 2021 · The Richter scale measures the magnitude of an earthquake's largest jolt of energy. This is determined by using the height of the waves recorded on a seismograph. The Richter scale is logarithmic. The magnitudes jump from one level to the next. The height of the largest wave increases 10 times with each level. So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce. Magnitude scales, like the Richter magnitude and moment magnitude, measure the size of the earthquake at its source. So they do not depend on where the measurement is made. Often, several slightly ...Living in Earthquake Country: A Teaching Box — 7 lessons with the goal of teaching students about how and why earthquakes cause damage.
