What is a seisometer?
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.
Which earthquake waves are horizontal?
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.
How do Rayleigh waves move the ground?
Rayleigh waves move the ground in a rolling motion, similar to ocean waves. They cause particles of material to move elliptically in the direction of wave propagation, leading to both vertical and horizontal motion. This motion is what can cause significant horizontal shaking and damage during an earthquake.
What is the tracing of an earthquake motion created by a seismograph?
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.
Waves that can make the ground roll like ocean waves they usually cause the most damage during an earthquake?
These are known as seismic surface waves. They travel along the Earth's surface and cause the ground to move in a rolling motion. They are responsible for the most damage during an earthquake as they can generate strong shaking and displacement of structures.
What is the instrument used for recording the intensity and duration of an eartquake?
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.

What specific aspect of an earthquake does a seismograph measure?
A seismograph measures the ground motion caused by seismic waves generated during an earthquake. It detects and records vibrations in the Earth’s crust, capturing data on the amplitude, frequency, and duration of these movements. This information is vital for determining the earthquake's magnitude and understanding its impact.
Which earthquake waves are horizontal?
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.
What types of seismic waves produce the most damage during an earthquake?
Surface waves (e.g. Rayleigh waves, Love waves) that produce vertical motion of the ground surface produce the most damage during an earthquake.
This is used to record the shaking?
A seismograph is used to record shaking or vibrations in the Earth's crust. It consists of a sensitive instrument that detects ground motion caused by seismic waves during an earthquake. The information recorded by a seismograph helps scientists determine the location, intensity, and duration of an earthquake.
What measures the ground motion during an earthquake?
Seismometers are instruments that measure ground motion during an earthquake. They detect the movement of the ground caused by seismic waves passing through the Earth. The data recorded by seismometers can help scientists analyze and characterize earthquakes.
How do Rayleigh waves move the ground?
Rayleigh waves move the ground in a rolling motion, similar to ocean waves. They cause particles of material to move elliptically in the direction of wave propagation, leading to both vertical and horizontal motion. This motion is what can cause significant horizontal shaking and damage during an earthquake.
What is a seismogragh and what does it do?
A seismograph is a device that detects and measures the magnitude and duration of seismic waves caused by earthquakes and other sources of ground motion. It records the ground motion as a seismogram, which helps seismologists analyze and understand the characteristics of earthquakes.
How does a seismograph detect and record sesamograph detect and record seismic waves?
A seismograph detects seismic waves by using a heavy mass suspended on a spring, which remains relatively still while the ground shakes during an earthquake. As seismic waves pass through the Earth, they cause the ground to move, leading to relative motion between the ground and the mass. This movement is recorded on a rotating drum or digital system, creating a seismogram that visually represents the amplitude and frequency of the seismic waves. By analyzing these records, scientists can determine the location, depth, and magnitude of the earthquake.
