Definition. The intensity, or macroseismic intensity, represents a classification of the severity of ground-motion shaking during an earthquake on the basis of observed effects at a given place. The word “macroseismic” refers to perceptible effects of earthquakes as opposed to instrumental observations.Oct 3, 2023 · The severity of an earthquake is measured on the Richter scale, with higher numbers indicating greater intensity. Earthquakes can cause damage to buildings, infrastructure, and the landscape. They can also lead to landslides, tsunamis, and in some cases, loss of life. Preparedness and Safety: Living in earthquake-prone areas means being prepared. The meaning of MICROEARTHQUAKE is an earthquake of low intensity. Recent Examples on the Web Earthquakes like the one recorded on the Alabama-Georgia border are known as microearthquakes and are not usually felt by people.PGA is an important parameter (also known as an intensity measure) for earthquake engineering, The design basis earthquake ground motion (DBEGM) is often defined in terms of PGA. Unlike the Richter and moment magnitude scales, it is not a measure of the total energy (magnitude, or size) of an earthquake, but rather of how much the earth shakes ... The energy of a magnitude 5 earthquake is 31 times the energy of a magnitude 4 earthquake. Earthquake magnitudes are determined from seismic waves, the ground-bending waves generated by the earthquake fault. The energy in these waves lessens with distance. As you move farther from the earthquake fault, the intensity of the shaking decreases.
Seismic intensity scales categorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake. They are distinguished from seismic magnitude scales, which measure the magnitude or overall strength of an earthquake, which may, or perhaps may … See more

The word “macroseismic” refers to perceptible effects of earthquakes as opposed to instrumental observations.Inertial forces - Earthquake generated vibration of the building's mass causing internally generated inertial forces and building damage. Inertial forces are the product of mass times acceleration (F = m a). Intensity - A subjective measure of the force of an earthquake at a particular place as determined by its effects on persons, The energy of a magnitude 5 earthquake is 31 times the energy of a magnitude 4 earthquake. Earthquake magnitudes are determined from seismic waves, the ground-bending waves generated by the earthquake fault. The energy in these waves lessens with distance. As you move farther from the earthquake fault, the intensity of the shaking decreases.Magnitude is the size of the earthquake. An earthquake has a single magnitude. The shaking that it causes has many values that vary from place to place based on distance, type of surface material, and other factors. See the Intensity section below for more details on shaking intensity measurements.
The Modified Mercalli Intensity Scale The effect of an earthquake on the Earth's surface is called the intensity. The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally--total destruction.
Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations.
The size and damaging effects or severity of an earthquake are described by measurements of both magnitude and intensity.

Earthquakes are recorded by a seismographic network. Each seismic station in the network measures the movement of the ground at that site. The slip of one block of rock over another in an earthquake releases energy that makes the ground vibrate.
A fault line may send out tiny shocks, called foreshocks, days or even weeks before a major earthquake. When a fault line is about to rupture and cause an earthquake, the types of waves it sends out change.The MCER is a ground shaking intensity, given as a response acceleration, which is generally caused by a range of earthquakes of different magnitudes from ...Beyer K, Bommer JJ (2006) Relationships between median values and between aleatory variabilities for different definitions of the horizontal component ...
