Seismograph.
Earthquakes are measured by a seismometer, also known as a seismograph.
The device used to detect earthquakes is called a seismometer or seismograph. It measures the ground motion caused by seismic waves generated during an earthquake. By recording this data, seismometers help scientists analyze the magnitude and location of earthquakes.
The seismograph's mass, typically a heavy weight or pendulum, remains stationary during an earthquake. Its inertia allows it to stay in place while the ground moves. This mass is connected to a recording device that captures the motion caused by seismic waves during an earthquake.
A seismograph is the instrument used for recording the intensity and duration of an earthquake. It detects and measures the motion and vibrations of the ground caused by seismic waves.
Intense vibrations felt throughout Earth's crust during an earthquake are called seismic waves. These waves are responsible for shaking and transmitting energy through the Earth's layers, leading to the ground motion experienced during an earthquake.
The Richter Scale is what measures the ground motion from an earthquake.
A seismometer is a device that measures ground motion during earthquakes. It detects and records the intensity and duration of seismic waves, providing valuable data for studying and monitoring seismic events.
Earthquakes are measured by a seismometer, also known as a seismograph.
A seismometer or seismograph detects the motion of ground waves during an earthquake. These instruments measure the vibrations of the ground caused by seismic waves and help scientists monitor and study earthquakes.
The tracing of an earthquake motion created by a seismograph is known as a seismogram. It represents the ground motion recorded by the seismograph during an earthquake, displaying the amplitude and duration of seismic waves. Seismologists use seismograms to determine the magnitude, location, and depth of an earthquake.
A seismograph is a device that records the motion of the ground resulting from seismic waves caused by earthquakes, volcanic eruptions, or other seismic sources. It consists of a moving mass suspended on a spring that remains relatively static during ground motion, allowing the recording of seismic waves.
how do particles move in the ground when an earthquake occurs
An earthquake.
Surface waves are the earthquake waves that move in a horizontal direction along the ground. They are responsible for the most damage during an earthquake due to their side-to-side shaking motion.
The ground motion of a magnitude 5 earthquake is 100 times greater than that of a magnitude 3 earthquake. This is because each whole number increase in magnitude represents an increase in amplitude by a factor of 10.
Surface waves (e.g. Rayleigh waves, Love waves) that produce vertical motion of the ground surface produce the most damage during an earthquake.
Ground motion increases logarithmically with each unit increase in earthquake magnitude. Therefore, the ground motion would be approximately 10 times greater for a magnitude 5.5 earthquake compared to a magnitude 4.5 earthquake.
