A seismograph is an instrument that measures the seismic wave activity in an area. According to Wikipedia, Seismometersare instruments that measure and record motions of the ground, including those of seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources. A seismic wave, according to wikipedia is, "Seismic waves are waves of force that travel through the Earth or other elastic body, for example as the result of an earthquake, explosion, or some other process that imparts forces to the body. Seismic waves are also continually excited on Earth by the incessant pounding of ocean waves (referred to as the microseism) and the wind."Seismograph is another Greek term from seismós and γράφω, gráphō, to draw. It is often used to mean seismometer, though it is more applicable to the older instruments in which the measuring and recording of ground motion were combined than to modern systems, in which these functions are separated. Both types provide a continuous record of ground motion; this distinguishes them from seismoscopes, which merely indicate that motion has occurred, perhaps with some simple measure of how large it was.

The distance between an earthquake epicenter and the location of a seismograph can be calculated because?

The time it takes for seismic waves to reach the seismograph can be used to calculate the distance between the epicenter and seismograph. By knowing the average speed of seismic waves in the earth, the time difference between the arrival of P- and S-waves can be used to determine the distance.


What is the instrument called that detects seismic waves?

The instrument that detects seismic waves is called a seismometer or seismograph. It measures the vibrations caused by seismic waves in the Earth's crust and can help to monitor and study earthquakes.


How you can use the words seismic wave and seismograph in the same sentence?

The seismograph measured the intensity of the seismic waves


Instrument that records seismic waves?

A seismograph.


What is the difference between seismograph and tsunami?

A seismograph is an instrument used to measure seismic waves in the earth's crust. In other words a seismograph detects earthquakes. A tsunami occurs when there is an earthquake at sea. The earthquake causes colossal tidal waves to form and the waves crash onto shore. This is a tsunami.


Which seismic wave arrives last at a seismograph station?

The first waves to arrive at a seismograph station are primary waves, or P waves.


What is a seismograph and what causes it?

What device is used to record seismic waves?

A seismometer or seismograph is a device used to record seismic waves generated by earthquakes or other sources. It detects and measures the vibrations caused by these waves, providing valuable data for studying the Earth's interior and understanding seismic activity.


What types of waves are the first waves to reach seismograph stations?

P-waves are the first seismic waves to arrive at a seismograph station.

What is the difference between seismograph and epicenter?

i might be a 6th grader but i can still awnser you question we had talk about this not to long ago and what i can remember is that a seismograph is an interment that measures and records seismic waves and the epic center a point on earth's surface right above the focus of an earthquake i hope this helped! :3
