the instrument which detects and records the intensity of seismic waves generated by an earthquake is called seismigraph where as the graphical record of the intensity of sesmic waves is called seismogram. Then, what are the three types of seismographs?
To overcome this problem, modern seismograph stations have three separate instruments to record horizontal waves - (1) one to record the north-south waves, (2) another to record east-west waves, and (3) a vertical one in which a weight resting on a spring tends to stand still and record vertical ground motions.
Similarly, what is seismologist? Seismology is the scientific study of earthquakes and related phenomena, such as volcanic eruptions. Seismologists also apply what they learn from studying the Earth's structure and other geological events, such as tsunamis, for commercial and other purposes, such as detecting nuclear explosions.
Moreover, what is the difference between seismograph and Richter Scale?
A seismograph is an instrument used to detect and record earthquakes. It is also known as a seismometer. It records the motion of the ground during a quake. The Richter scale is a numerical value used to measure the power or magnitude of earthquakes.

Where are seismographs kept?
A seismograph is an instrument that records waves caused during an earthquake. It is usually kept at geological centres. Are seismographs still used today?
Seismographs are instruments used to measure seismic waves produced by earthquakes. Scientists use these measurements to learn more about earthquakes. While the first seismograph was made in ancient China, today's modern instruments are based on a simple design first created in the 1700s. How does a seismogram work?
A seismograph is a device for measuring the movement of the earth, and consists of a ground- motion detection sensor, called a seismometer, coupled with a recording system. Seismographs operate on the principle of inertia. Modern research seismometers are electronic, and detect and record motions in all directions. How do seismographs help us?
A seismometer, or seismograph, is a device that geologists use to measure and record seismic waves. By studying these recordings, scientists can map the earth's interior, and they can measure or locate earthquakes and other ground motions. How accurate are seismographs?
Modern seismometers are accurate enough to register even the tiniest ground movements of only a few nanometres – in other words, of a millionth of a millimetre. The strength of the earthquake is determined from the measured amplitudes and the distance to the hypocentre of the earthquake. Which is known as seismic wave?
A seismic wave is an elastic wave generated by an impulse such as an earthquake or an explosion. Seismic waves may travel either along or near the earth's surface (Rayleigh and Love waves) or through the earth's interior (P and S waves). What is the max on the Richter scale?
In theory, the Richter scale has no upper limit, but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6. (That was the Richter magnitude for the Chile earthquake of 1960. The moment magnitude for this event was measured at 9.5.). What is the formula for the Richter scale?
The Richter scale defines the magnitude of an earthquake to be R=log(IcIn) where Ic is the intensity of the earthquake and In is the intensity of a standard earthquake. What does a Richter scale?
The Richter scale is used to rate the magnitude of an earthquake -- the amount of energy it released. This is calculated using information gathered by a seismograph. The Richter scale is logarithmic, meaning that whole-number jumps indicate a tenfold increase. In this case, the increase is in wave amplitude. What is the highest ever recorded earthquake?
Valdivia Earthquake
What is Richter scale and seismometer?
The Richter scale rates the amount of energy released from a single earthquake, letting us know the magnitude of the disaster. A seismograph is what scientists use to actually measure the earthquake and the Richter scale is a way of putting the data into an understandable context. Is Richter scale a device?
The Richter scale is a logarithmic scale, meaning that the numbers on the scale measure factors of 10. A seismograph is the device that scientists use to measure earthquakes. The goal of a seismograph is to accurately record the motion of the ground during a quake. What is the difference between Richter scale and Mercalli scale?
Richter Scale. While the Mercalli scale describes the intensity of an earthquake based on its observed effects, the Richter scale describes the earthquake's magnitude by measuring the seismic waves that cause the earthquake.
