What four instruments are used to monitor faults? Tiltmeters, creep meters, laser-ranging device, and GPS satellite.
How does a seismograph detect and record seismic waves?
The spring-suspended mass lags behind the motion caused by the earthquake, making the pen record the waves on the drum. This combination of instruments tells a seismologist the general direction of the seismic wave source, the magnitude at its source, and the character of the wave motion.
What does a seismograph record?
Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network.
What instrument measures vertical movement?
seismometers How do seismometers measure vertical ground motion? Animation of the principles of a drum-style vertical seismograph station that records up-and-down movement. Seismographs are designed so that slight earth vibrations move the instrument.
What instrument is used to measure and record ground movements during an earthquake?
Seismographs A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with "seismograph". Seismographs are instruments used to record the motion of the ground during an earthquake.
What instruments measure deformation along a fault?
Tiltmeters are highly sensitive instruments used to measure ground tilt (rotation) near faults and volcanoes caused by fault slip and volcanic uplift.
What are tiltmeters used for?
Tiltmeters and strainmeters measure subtle changes in ground slope and shape at volcanoes | U.S. Geological Survey. A .
What is seismograph used for?
Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network. The earliest "seismoscope" was invented by the Chinese philosopher Chang Heng in A.D. 132.
What is the name of the instrument used for measuring earthquake?
Moment magnitude, Richter scale – what are the different magnitude scales, and why are there so many? Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept.
What is the instrument used to measure an earthquake?
seismograph A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with "seismograph". Seismographs are instruments used to record the motion of the ground during an earthquake.
What is Richter scale and seismograph?
The Richter scale is used to rate the magnitude of an earthquake, that is the amount of energy released during an earthquake. On the other hand, a seismograph is an instrument used to detect and record seismic waves.
What is a vertical seismograph?
Drum-style vertical seismograph station records up-and-down movement. Seismographs are designed so that slight earth vibrations move the instrument. The suspended mass remains at rest as the spring absorbs some of the motion.
What is Richter scale used to measure?
The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.
Which the following is a instrument used the measure the motion?
Stay updated with the General Science questions & answers with Testbook. Know more about Physics and ace the concept of Measuring Instruments….Detailed Solution.
| Instrument | Use |
|---|---|
| Odometer | Measures distance travelled by vehicle |
| Seismometer | Measures motion of the ground (earthquake/seismic waves) |
Which instrument is used to measure the deflection of earthquake?
seismographs To record seismic waves and measure their intensity, scientists use special measuring devices called “seismographs.” Seismographs record the vibrations of rock at the place of installation. Amplitude of the vibrations is determined by measuring the maximal height of deflections (during one period of vibration).
What 4 instruments are used to monitor faults?
The four instruments used to monitor faults are the tiltmeters, which measure the vertical movement or the tilting of the surface; the creep meters, which measure the horizontal movement of the fault; the laser-ranging devices, which detect the fault's horizontal movement using a laser beam; and the GPS satellites, …
What is the Richter scale?
The Richter magnitude scale, also known as the local magnitude (M) scale, assigns a number to quantify the amount of seismic energy released by an earthquake. It is a base-10 logarithmic scale.
What are monitoring instruments?
The Monitoring Instruments are an open and transparent means to describe the practical response, over time, of the SEE countries to the commitments made in the Investment Compact, and, more generally, their commitment to the broader objectives of transition.
What is seismograph and Richter scale?
The Richter scale is used to rate the magnitude of an earthquake, that is the amount of energy released during an earthquake. On the other hand, a seismograph is an instrument used to detect and record seismic waves.
Is Richter scale still used?
While the Richter scale is not obsolete, the universal measurement today is the moment magnitude scale. The Richter scale was developed by seismologist Charles Richter (1900-1985) in the 1930s to bring consistent, objective criteria to evaluating the size of earthquakes.
Which instrument is used for measuring earthquake?
seismograph A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with "seismograph". Seismographs are instruments used to record the motion of the ground during an earthquake.
What does the Mercalli scale measure?
The Mercalli Scale is based on observable earthquake damage. From a scientific standpoint, the magnitude scale is based on seismic records while the Mercalli is based on observable data which can be subjective.
What does the Richter scale measure?
The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.

Which of the following instruments determines the ground motion of an earthquake?
A seismometer is an instrument that responds to ground motions, such as caused by earthquakes, volcanic eruptions. Richter scale a quantitative measure of an earthquake's magnitude.
What does seismograph measure?
A seismograph, or seismometer, is an instrument used to detect and record earthquakes. Generally, it consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage.
