It refers to the study of how bright a star actually is or how bright it appears to be. The brighter it appears, the lower its magnitude value is. Magnitude can be both positive and negative. The way stars look to us is what we refer to as Apparent Magnitude. A star that looks very faint might be a lot brighter than a star that looks brighter star, because the fainter looking star is much further away. If both were the same distance from us, the fainter star might look a lot brighter than the other star. The actual brightness of stars in this way is called the Absolute Magnitude of a star.

∙ 13y agoA magnitude scale provides an estimate of the total energy released in an earthquake. It is commonly derived based on the amplitude of seismic waves or if information is available, the size of fault displacement and the stiffness of the rockmass around the fault zone.

∙ 12y agoThe moment magnitude scale (MW) provides an estimate of the total energy released in an earthquake and is currently the preferred magnitude scale in use by seismologists for measuring large (magnitude greater than 7) earthquakes.

∙ 12y agoNo, magnitude means a stars brightness. It has two types of magnitude: Apparent, (how bright is seems to us, a function of how far away it is) and absolute (how bright is is in comparison to other stars, that is, it's "real" magnitude).

Magnitude is an earthquake's what?
The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.
What is earthquake magnitude and how is it measured?
magnitudea measure of the amount of the energy released by earthquake . earthquake is measure through Ricthter scale that measure the magnitude of seismic waves that it has
What system do geologists use today for rating the magnitude of an earthquake?
They use the Richter scale to measure magnitude and Moment Measure to measure energy released.
How is the strength of an earthquake measured?
You use a seismograph to measure the strength of an earthquake.
What scale is used to measure the energy of an earthquake?
A magnitude scale. Formerly the Richter magnitude scale was used, but this has now been replaced by the Moment magnitude scale.
What is an earthquake's magnitude a measure of?
An earthquake's magnitude is a measure of how strong it is
Magnitude is an earthquake's what?
The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.

What are the measure of the strength of an earthquake is called?
The Richter magnitude scale is used to measure the strength of an earthquake.
What is used to measure the strength of a earthquake?
The Seismograph is used to measure the Magnitude of an earthquake.
What scales are used to measure the magnitude of earthquakes?
The instrument that is used to measure the magnitude of an earthquake is a seismometer.
What is magnitude and how is it measured?
magnitudea measure of the amount of the energy released by earthquake . earthquake is measure through Ricthter scale that measure the magnitude of seismic waves that it has
What is an earthquake's strength?
Depends on it's magnitude which can range. Seisometers are used to measure the Magnitude of an earthquake. Magnitude is it's strength.
What term means the measure of energy released by an earthquake?
The measure of energy released by an earthquake depends on its magnitude. If its a high magnitude earthquake, there is a lot of energy. If there is a low magnitude, then there is little energy.
What is a sentence with magnitude?
The magnitude of an earthquake is a measure of the energy that is released by the event.
What scale is used to measure the strength (magnitude) of an earthquake?
Richter Magnitude
What are the advantages the moment magnitude scale to measure an earthquake?
to rate an earthquake
