What instrument measure the intensity of earthquakes?
Strong-motion seismometers (which are also known as Accelerographs) are used to measure the intensity of earthquakes. It should be noted that intensity is different from magnitude and is measured using a differing scale (Moddified Mercalli or Macroseismic scale for intensity vs Moment Magnitude scale for earthquake magnitudes.)Seismometers / accelerometers measure the intensity of earthquakes.Seismometers - instruments that measure motions of the ground.The visual output, either on a monitor or on paper is called a seismographSeismometers are in part used to measure the intensity of earthquakes. The scale used to measure earthquake intensity is known as the Modified Mercalli scale. A variation of this is used in Europe and is known as the Macroseismic scale.Earthquakes are measured with a seismometer.Seismometers and accelerometers are used to measure the acceleration of the ground surface and the total amplitude of seismic waves during an earthquake.These values are used by seismologists to find the intensity of the earthquake (along with observations of the damage done to structures).Earthquakes are measured using machines called SEISMOMETERS which record the shaking as waves on a graph .The magnitude of most earthquakes is measured on the Richter scale, invented by Charles F. Richter in 1934. The Richter magnitude is calculated from the amplitude of the largest seismic wave recorded for the earthquake, no matter what type of wave was the strongest.

Scale used to measure earthquakes?
The oldest scale of measurement for earthquakes were in fact intensity rather than magnitude scales with the first being The Mercalli intensity scale. Intensity scales describe the earthquake in terms of the damage caused. Later, improved versions of this form of measurement were published in 1931 as the Mercalli-Wood-Neumann scale.The first widely accepted magnitude scale (magnitude being a description of the energy released by an earthquake) was developed by Charles Richter in 1935. This was known as the Richter magnitude scale (also known as the Local Magnitude Scale), which categorises them in absolute terms based on calculating the logarithm of their amplitude and the distance of the seismometer station from the epicentre. The Richter scale was designed to measure the magnitude of moderate and small earthquakes. The scale has no theoretical upper or lower bounds, however in practical terms the lower bound is defined by the minimum sensitivity of seismometers and their ability to detect small earthquakes and the upper limit (effectively around a magnitude of 7.0) is due to the fact that earthquakes larger than this due to the wavelength of seismic waves produced by large earthquakes.In order to attempt to overcome this, Charles Richter along with his colleague Beno Gutenberg developed the surface and body wave magnitude scales. These produce results that are consistent with the original magnitude scale and extend it's utility up to earthquake with a magnitude of 8.0For earthquakes larger than magnitude 7-8 a new scale was required and this was developed in the 1970s and is known as the Moment Magnitude Scale (MMS) which measures the earthquakes magnitude based on the length of the fault that slips, the amplitude of the fault movement and the elastic moduli of the rockmass around the fault zone.The modern scale retains the familiar logarithmic continuum of values with the original Richter (local) magnitude scale.
What is the instrument and the scale that is used to measure the magnitude of an earthquake called?
The instrument is called "seismometer."The first sacle of measurment for earthquakes is called the richter magnitude scale after its inventor, Charles Richter (in 1935 ), which categorises them in terms obtained by calculating the logarithm of their amplitude.This scale has been replaced in the 1970s, by the moment magnitude scale which measures the size of earthquakes in terms of the energy released.The modern scale retains the familiar continuum of magnitude values defined by the older one.
What is the difference between Richter and Moment Magnitude scale?
the moment magnitude scale is used to measure earthquake magnitude-taking into account the size of the fault rupture, the rocks stiffness,and the amount of the movement of the fault- using values that can be estimated from the size of several types of seismic waves. while a Richter scale is a numerical scale used to measure the magnitude of an earthquake, using values based on the size of the earthquakes largest seismic waves.

What was the smallest earthquake to kill a person?
The magnitude measures the maximum motion recorded by a seismograph with of range of values typically from 0.1 to 10 through there is no real upper limit to the scale. An earthquakes with a magnitude less than 2.5 is considered minor and usually not felt, but can be recorded by seismograph. Magnitudes 5.0 to 5.9 is considered moderate. Deaths have been attributed to earthquakes with a magnitude low as 5.5, but it is still possible that person's death can be caused by an earthquake with a smaller magnitude either from fallen debris or a loose gas/electrical line.
Where are intensity values of an earthquake usually hightset?

What is is the magnitude of Virgo?
Virgo is a constellation made up of hundreds of stars and thus cannot have a magnitude,If you wish to add up the values and get an average values, go to the related link.
What instrument is used to measure the intensity of a earth quake?
Earthquake intensity is recorded on the Modified Mercalli or the Macroseismic scale. These values are derived based on witness reports as to the perceived level of ground shaking as well as damage to buildings and other structures and ground accelerations as measured by seismometers.
What numbers have equal absolute values?
A positive and negative number with the same magnitude (value) will have their absolute values equal.
