They use the Richter scale.

What is another variable besides damage that scientists measure to jugde the strength of an earthquake?
Scientists also measure the magnitude of an earthquake, which represents the total energy released at the source. Magnitude is typically measured on the Richter scale or the moment magnitude scale.
How do scientists measure an earthquake magnitude?
Scientists measure earthquake magnitude using seismometers, which detect and record ground motion. The most common scale used to measure earthquake magnitude is the Richter scale, which is based on the amplitude of seismic waves. More recently, the moment magnitude scale has become the preferred method for measuring earthquake magnitude as it provides a more accurate representation of the energy released during an earthquake.
What scale do scientists most often use today to express the magnitude of an earthquake?
Scientists most often use the Richter scale or the moment magnitude scale to express the magnitude of an earthquake. These scales measure the energy released by an earthquake and provide a numerical value to indicate its intensity.
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 an earthquake's magnitude a measure of?
An earthquake's magnitude is a measure of how strong it is
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.
How do scientists measure the size of earthquakes?
Scientists use seismographs to measure the magnitude of earthquakes. Seismographs detect the seismic waves generated by an earthquake, and the amplitude of these waves is used to calculate the earthquake's size. The most common scale used to measure earthquake size is the Richter scale or the moment magnitude scale.
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 was the magnitude of the earthquake?
7.2 magnitude
