In physics intensity is the energy density (that is, the energy per unit volume) multiplied it by the velocity at which the energy is moving. The resulting vector has the units of power divided by area, that is in watts per m². It is possible to define the intensity of the water coming from a garden sprinkler, but intensity is used most frequently with waves (i.e. sound or light).
Magnitude is a measure of the size of a mathematical object.
Volcanic activity is measured by a Volcanic Explosivity Index. VOI.
Earthquakes are measured either by Modified Mercalli Scale, if one is interested in building behaviour; or the Richter scale (or its modifiers) if one is concerned with the source energy of earthquakes.
Stars also have a magnitude scale for comparison.
in what unit is the magntude of force measured

A unit vector.
Many do. For instance, you would probably agree that your own height and weight are physical quantities. Each of these has a magnitude or size and a unit of measurement. They might be, say, 157 cm and 50 kg.
(any unit of length) / (any unit of time) is a unit that can be used for the magnitude (size) of velocity, and must always be accompanied by a description of direction. Without it, all you have is a speed, not a velocity.
Basically, a unit is a type of standard against which a measurement is compared. For example: the standard unit of length is the meter. If you claim that your house (for example) measures 9 meters from north to south, then you are really claiming that the length of your house is 9 times as much as a meter.
A magnitude is a pure number - with no SI unit.

A magnitude is a number and so has no units.
That's what "unit" means.
magnitude
No, by definiton, a unit vector is a vector with a magnitude equal to unity.
The unit vector is a vector whose magnitude is 1.
a vector having unit magnitude and have a certain direction.
Richter scales are used to measure the magnitude of an earthquake. There is no specific unit used for earthquakes. I hope this helps. =)
It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.
Distance can be fully described with a magnitude and a unit. It is a scalar quantity, which means it has a magnitude (numerical value) but not a direction. A related quantity is displacement, which is the straight line distance from a starting point to an ending point. Displacement is a vector quantity, so it can only be fully described with a magnitude, a unit, and and direction.
