It is a device called a seismographe. It is used to determine the magnitude on a scale which is then deciding how bad the earthquake is.
The Seismograph is used to measure the Magnitude of an earthquake.
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
It depends on how big the earthquake is. A big earthquake will cause more damage to the area.
Measure the size of the earthquake.
a Seismograph measure earthquake vibrations
An earthquake's magnitude is a measure of how strong it is
PAGASA used richter scale to measure the intensity of an earthquake
The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.
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
to rate an earthquake
You use a seismograph to measure the strength of an earthquake.
The Richter magnitude scale is used to measure the strength of an earthquake.
