The severity of an earthquake in terms of its effects on the earth's surface, and buildings. The value depends on the distance from the epicentre, and is not to be confused with the magnitude
{i} quality of being intense; strength, energy; strength of feeling; extreme degree; depth; clarity, amount of light emitted from a graphics device or from a pixel (Computers)
1 In visual perception, one of the three basic parameters (hue, intensity, and saturation) which may be used to describe the physical perception of color Intensity is a measure of the energy of the spectral distribution, at a given point in an image or scene, weighted by the spectral response of the visual system Luminance is the energy of the physical spectrum, but not weighted by the visual response Brightness sometimes is used synonymously with either term See chromaticity 2 In photometry, a measure, sometimes called specific intensity of the amount of radiant energy received per unit solid angle per unit time per unit area of a surface element orthogonal to the direction of propagation of the radiation 3 In radio astronomy, a term often used much more loosely to mean either the flux density of an unresolved radio source or the surface brightness of an extended source The normalization and the units must be determined from the context because of the looser usage
The square of the electric field strength of an electromagnetic wave Note: Intensity is proportional to irradiance and may be used in place of the term "irradiance" when only relative values are important
A measure of shaking strength of an earthquake at a particular location Intensity is largest at the epicenter and decreases in all directions from the epicenter Intensity is measured by the Modified Mercalli scale, from I (not felt except by few) to XII (damage total)
The amount of energy of any radiation incident upon (or flowing through) unit area, perpendicular to the radiation beam, in unit time The intensity of thermal radiation is generally expressed in calories per square centimeter per second falling on a given surface at any specified instant As applied to nuclear radiation, the term intensity is sometimes used, rather loosely, to express the exposure (or dose) rate at a given location
per unit of surface, or of volume, as the case may be; as, the measure of the intensity of a total stress of forty pounds which is distributed uniformly over a surface of four square inches area is ten pounds per square inch
The strength of a signal, such as light or sound For light, the intensity is the brightness, for sound it is the volume For a given wavelength of light, the intensity tells you how much how much of that color of light is being produced by the source Use the "back" button to return to the lesson
Measure of the flow of power emitted by a surface Intensity is expressed in watts (W) per square meter In other words, how much light is concentrated in an area If two bulbs are reflecting onto the same surface with one burning at 100 W and another at 60 W, there is more intensity from the 100 W bulb because more energy is being transferred to the same area
A measure of the effects of an earthquake at a particular place on humans and (or) structures The intensity at a point depends not only upon the strength of the earthquake (magnitude) but also upon the distance from the earthquake to the epicenter and the local geology at that point
high level or degree; the property of being intense the amount of energy transmitted (as by acoustic or electromagnetic radiation); "he adjusted the intensity of the sound"; "they measured the station's signal strength
A measure of the severity of shaking at a particular site It is usually estimated from descriptions of damage to buildings and terrain The intensity is often greatest near the earthquake epicenter Today, the Modified Mercalli Scale is commonly used to rank the intensity from I to XII according to the kind and amount of damage produced Before 1931 earthquake intensities were often reported using the Rossi-Forel scale
The square of the electric field strength of an electromagnetic wave Intensity is proportional to irradiance and may get used in place of the term "irradiance" when only relative values are important
in terms of acoustic output, the term "High Intensity" is favored herein in lieu of "High Power" because high intensity is required for cavitation A 1/16" (1 6mm) diameter tip on a probe does not require much power at all to radiate at high intensity whereas a large sonar array may soak up enormous power while radiating at very low intensity
A number (written as a Roman numeral) describing the severity of an earthquake in terms of its effects on the earth's surface and on humans and their structures Several scales exist, but the ones most commonly used in the United States are the Modified Mercalli scale and the Rossi-Forel scale There are many intensities for an earthquake, depending on where you are, unlike the magnitude, which is one number for each earthquake
the amount of energy transmitted (as by acoustic or electromagnetic radiation); "he adjusted the intensity of the sound"; "they measured the station's signal strength"
A subjective measure of the force of an earthquake at a particular place as determined by its effects on persons, structures, and earth materials Intensity is a measure of effects as contrasted with magnitude, which is a measure of energy The principal scale used in the U S today is the Modified Mercalli, 1956 version
A measure of the effects of an earthquake at a particular place on humans, structures and (or) the land itself The intensity at a point depends not only upon the strength of the earthquake (magnitude) but also upon the distance from the earthquake to the point and the local geology at that point
A measure of the extent to which a tract of land is developed Residential density in units per acre is a measure of intensity; floor area ratio is also a measure of intensity, as is square feet per acre Intensity can also be described or measured in terms of impacts such as traffic loading, sewage disposal needs, etc
For gamma-ray bursts, a measure of the strength of a burst It is measured as the number of photons crossing a given surface (i e the detector) per second
