Because magnitude is a measurement of the amount of energy released in an earthquake and this value will remain constant once the earthquake has finished. However the estimates seismologists make of this value may change as they gain more information about the earthquake...

What is the Magnitude of an earthquake and how big was the earthquake in Japan?

The magnitude of an earthquake is a number used to quantify how much energy was released during the earthquake. The earthquake in Japan that occurred on Friday, March 10, 2011, had a moment magnitude of 8.9.


What is an earthquake's magnitude a measure of?

An earthquake's magnitude is a measure of how strong it is


What is the strongest magnitude earthquake ever measured on the Richter magnitude?

The strongest earthquake that can be measured using the Richter magnitude scale is one with a magnitude of 8.0. For earthquakes larger than this, the moment magnitude scale must be used.


Another word for an earthquake's strength is what?

Another word for an earthquake's strength is magnitude. Magnitude is a measure of the size of the seismic waves produced by an earthquake.


What is the difference in strength between a 7.0 magnitude earthquake and a 9.0 magnitude earthquake?

-3.0 magnitude or if you want the ground motion: Each time the magnitude increases by one unit, the measured ground motion becomes 10 times larger. For example, an earthquake with a magnitude of 5.0 on the Richter scale will produce 10 times as much ground motion as an earthquake with a magnitude of 4.0. Furthermore, an earthquake with a magnitude of 6.0 will produce 100 times as much ground motion (10 × 10) as an earthquake with a magnitude of 4.0.


How does the magnitude change with each number on the scale?

Each number on the scale represents a tenfold increase in magnitude. For example, an earthquake with a magnitude of 5 is ten times stronger than one with a magnitude of 4, and one with a magnitude of 6 is one hundred times stronger than a magnitude 4 earthquake.


How much larger is an earthquake with a magnitude of 9 than an earthquake with a magnitude of 4?

An earthquake with a magnitude of 9 is 10,000 times larger in amplitude than an earthquake with a magnitude of 4 on the Richter scale. This means that the energy released by a magnitude 9 earthquake is significantly greater than that of a magnitude 4 quake.


What word describes the strength of an earthquake?

The strength of an earthquake is measured by its magnitude, which indicates the amount of energy released at the earthquake's source. Earthquake magnitude is typically reported on the Richter scale or the moment magnitude scale.


What is the highest ranked magnitude of an earthquake in the US?

There was a 9.2 magnitude earthquake in Prince William Sound, Alaska in 1964.


What can you learn from only one seismogram?

From one seismogram, you can learn about the timing, magnitude, and location of an earthquake. By analyzing the wave patterns captured on the seismogram, seismologists can determine the earthquake's Richter magnitude, depth, and distance from the seismograph station that recorded it.


Approx how many times more powerful is an earthquake with a score of 7 than 1 with a score of 6?

An earthquake with a magnitude of 7 is 10 times more powerful than an earthquake with a magnitude of 6. This is because the magnitude scale is logarithmic, meaning that for each whole number increase in magnitude, the amplitude of the earthquake's waves increases tenfold.
