What is the intensity of an earthquake.
The intensity of an earthquake is the estimated power of the phenomenon, which is “measured” by its impact on the surface of the earth, people and buildings. Intensity is assessed by consequences visually and/or by interviewing eyewitnesses.

Monitoring Earthquakes. We monitor earthquakes by measuring the seismic waves they generate. Seismic waves are generated when the two sides of a fault rapidly slip past each other. Measuring these waves help us determine the type of earthquake, its origin, and its strength/intensity. Many faults do not break the surface in an earthquake, so ...The Modified Mercalli Intensity Scale of 1931 is the basis for the U.S. evaluation of seismic intensity. Intensity is different than the magnitude in that it is based on observations of the effects and damage of an earthquake, not on scientific measurements. This means that an earthquake may have different intensities from place to place, but ...The two largest earthquakes in the recent series are relatively shallow, with the mainshock 18 kilometers, or 11 miles, deep and the 7.5 magnitude aftershock at 10 kilometers (just over 6 miles) deep. Because the quakes are relatively shallow, the intensity of the shaking is severe.What makes an earthquake "significant"? Events in this list and shown in red on our real-time earthquake map and list are considered “significant events’, and they are determined by a combination of magnitude, number of Did You Feel It responses, and PAGER alert level.Earthquake shaking is measured using the Modified Mercalli Intensity (MMI) Scale. Whereas the magnitude of an earthquake describes how much energy is released by an earthquake, calculated according to the length of a fault rupture and how far it slipped, the MMI scale describes the intensity of earthquake shaking at a specific location by considering its effects on people, objects and buildings.

Thus, the Mercalli scale describes ...The magnitude of an earthquake is a single value that describes the size of the earthquake at its source. Intensity is the measure of shaking at different locations around the earthquake. Intensity values vary from place to place, depending on the distance from the earthquake and the underlying rock or soil makeup. Magnitude and intensity are terms used in different contexts: magnitude is the size or quantity of something, such as the strength of an earthquake, while intensity is the subjective effects or impact of an event, such as the level of damage caused by an earthquake.The equation used to calculate sound intensity level in decibels is: d B = 10 log ( I I 0) In this equation, I 0 = 1 × 10 − 12 W m 2.
