January 1, 1982. Earthquakes can be measured in terms of either the amount of energy they release (magnitude) or the degree of ground shaking they cause at a particular locality (intensity). Although magnitude and intensity are basically different measures of an earthquake, they are frequently confused by the public and new reports of earthquakes.

Earthquake magnitude can be measured in a variety of ways, most commonly moment magnitude or Richter magnitude. Shaking is measured in units of acceleration, (often a percentage of g). Damage or intensity can be measured by the modified Mercalli intensity (MMI) scale. Magnitude and Location. Amount of shaking (g) Intensity (MMI)Objectives.

MODIFIED MERCALLI INTENSITY SCALE: The Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake, and is distinct from the moment magnitude usually reported for an earthquake (sometimes misreported as the Richter magnitude), which is a measure of the energy released. With regard to earthquakes, what distinguishes intensity from magnitude? A. intensity is a mathematical measure of how much shaking and vibration occurs, and the amount of energy that is related by the earthquake; magnitude is a rough subjective measure of local vibration and shaking and damage done.

Years ago, all magnitude scales were based on the recorded waveform lengths or the length of a seismic wave from one peak to the next. But for very large earthquakes, some magnitudes underestimated the true earthquake size.

How Are Earthquakes Measured? Two different viewpoints underpin the most important measurements related to earthquakes: magnitude and intensity. To scientists, an earthquake is an event inside the earth. To the rest of us, it is an extraordinary movement of the ground. Magnitude measures the former, while intensity measures the latter.

The duration of an earthquake is related to its magnitude but not in a perfectly strict sense. There are two ways to think about the duration of an earthquake. The first is the length of time it takes for the fault to rupture and the second is the length of time shaking is felt at any given point (e.g. when someone says "I felt it shake for 10 seconds" they are making a …

Magnitude calculations are based on a logarithmic scale, so a ten-fold drop in amplitude decreases the magnitude by 1.If an amplitude of 20 millimetres as measured on a seismic signal corresponds to a magnitude 2 earthquake, then:10 times less (2 millimetres) corresponds to a magnitude of 1;100 times less (0.2 millimetres) corresponds to ...
