The shaking of the ground makes the pen move up or down, or side to side, depending on what kind of seismograph it is. The pen then draws a graph, and the more the pen shakes, the the stronger the earthquake.
The magnitude of an earthquake is measured with a seismograph and the readout is measured using the Richter scale - See Sources and related links for more information.
The power of an earthquake is measured using a seismometer to record the seismic waves produced by the earthquake. The magnitude of an earthquake is typically measured using the Richter scale or moment magnitude scale.
Earthquake magnitude is measured using a number of differing scales including the Richter scale, the moment magnitude scale and the surface magnitude scale. Intensity is measured using he Modified Mercalli intensity scale.
The intensity of earthquakes is measured using the Modified Mercalli Intensity (MMI) scale, which assesses the effects of an earthquake at a given location. The energy released during an earthquake is measured using the moment magnitude scale (Mw), which takes into account the seismic moment and rupture length of the earthquake.
Earthquakes are measured using the Richter Scale, Moment Magnitude Scale, or the Modified Mercalli Intensity Scale. These scales take into account characteristics of the seismic waves and the effects of the earthquake on structures and the environment to determine its magnitude and intensity.
Earthquake strength is measured using the Richter scale or the moment magnitude scale. These scales quantify the amount of energy released by an earthquake. The Richter scale is based on the amplitude of seismic waves, while the moment magnitude scale considers the total energy released by the earthquake.
Earthquakes are measured using a seismograph. There is no exact science to predicting an earthquake. Scientists can only project the possibility of an earthquake occurring. This is based on measured seismic activity within a specific concentrated zone.
Earthquake waves (seismic waves) are measured using a seismograph or seismometer.
The degree to which people feel an earthquake is referred to as its intensity, typically measured using the Modified Mercalli Scale. The amount of damage an earthquake causes is known as its magnitude, often measured using the Richter Scale or moment magnitude scale.
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.
The shaking in an earthquake is measured using a seismometer. This device detects and records the vibrations produced by seismic waves during an earthquake. The magnitude of an earthquake is then determined based on the measurements recorded by seismometers.
The intensity of an earthquake is measured using the moment magnitude scale, which takes into account the seismic moment released by an earthquake. This scale assigns a single number to quantify the size of an earthquake, with each whole number increase representing a tenfold increase in amplitude. The strongest earthquake on record had a magnitude of 9.5.
