What scale do scientists most often use today to express the magnitude of an earthquake?
The Richter and moment magnitude scales (depending on the Earthquakes size).
What is used to mesure the size of an earthquake?
Scientists measure the magnitude (energy) of an earthquake using a seismograph (sort of sensitive pendulum that records the shaking of the earth).
Describe the scales that scientists use to measure the magnitude of an earthquake?
The most commonly referred to scale by the press and the public is the Richter scale for measuring earthquake magnitude. However this was actually replaced in the 1970s by the Moment Magnitude scale which is the magnitude scale favoured and in use by seismologists.
What is the difference in energy output between a magnitude 5 earthquake and a magnitude 6 earthquake?
A magnitude 6 earthquake has 10 ten times the energy of a magnitude 5 earthquake.
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 was the magnitude of the earthquake?
7.2 magnitude
What is the energy level difference between a magnitude 5 earthquake and magnitude 6 earthquake?
A magnitude 6 earthquake emits roughly 31 times more energy than a magnitude 5 earthquake. The magnitude 6 quake will also have a maximum seismic wave amplitude of ten times the magnitude 5 earthquake.
What magnitude was the earthquake that hit Chile?
The Earthquake of February 27,2010 had a magnitude of 8.8
What was the magnitude of the recent earthquake in haiti?
The magnitude of Haiti's recent earthquake was 7.0
Why is a 6.0 magnitude earthquake so much more destructive than a 5.0 magnitude earthquake?
Because the "magnitude scale is not linear, it is logarithmic (its numbers are an order of magnitude apart) this mean that the a magnitude 6 earthquake is TEN TIMES more powerful than a magnitude 5 earthquake and a HUNDRED TIMES more powerful than a magnitude 4 earthquake.
Why is 6.0 magnitude earthquake so much more destructive than a 5.0 magnitude earthquake?
Because the "magnitude scale is not linear, it is logarithmic (its numbers are an order of magnitude apart) this mean that the a magnitude 6 earthquake is TEN TIMES more powerful than a magnitude 5 earthquake and a HUNDRED TIMES more powerful than a magnitude 4 earthquake.
