- A seismograph is simply a device that can measure the intensity of a “seismic” type of activity such as an earthquake.But aside from the earthquake’s intensity, seismographs can also measure and record the earthquake’s duration and direction.he basic concept of seismographs or seismometers is that it involves an internal mass or weight since it will also move during an earthquake. Using a system of levers, weights, springs, and electronics in modern versions, seismographs are able to record information on the shaking of the ground.

Exploration Arguably the biggest breakthrough in petroleum and natural gas exploration came through the use of basic seismology. Seismology refers to the study of how energy, in the form of seismic waves, moves through the Earth’s crust and interacts differently with various types of underground formations. In 1855, L. Palmiere developed the first ‘seismograph’, an instrument used to detect and record earthquakes.

Pneumograph A pneumograph, also known as a pneumatograph or spirograph, is a device for recording velocity and force of chest movements during respiration. There are various kinds of pneumographic devices, which have different principles of operation. In one mechanism, a flexible rubber vessel is attached to the chest.

- There are two instruments, which are basically the same thing. There is the seismograph, and a more specific tool measures the waves on what is called the Richter scale. Eart … hquakes are given a number from one to ten, ten being the strongest. The strongest earthquake that their ever was, was measured a 9.3.plit and merge into it. Answer by Harlequin Williams. Confidence votes 67. A seismometer measures seismic waves; a seismograph registers and records them. Most scientists use something called a seismograph which is a machine with a pen on it which moves when shaking occurs on a rotating paper called a seismogram.

Frequently Asked Earthquake Questions A seismometer is a sensor placed in the ground to detect vibrations of the earth. A seismograph is an instrument that records these vibrations. A seismogram is the recording (usually paper or film) of the earth’s vibrations made by a seismograph.

Cochise College Student Papers in Geology Seismologists use two main devices to measure an earthquake: a seismograph and a seismoscope. The seismograph is an instrument that measures seismic waves caused by an earthquake. The seismograph has three main devices, the Richter Magnitude Scale, the Modified Mercalli Intensity Scale, and the Moment-Magnitude Scale.

Cochise College Student Papers in Geology One seismograph is needed to measure vertical motion, and two to record horizontal motion. The two seismographs recording horizontal directions, record in 90-degree angles (Kauffman and Judson 182). Seismographs record in a zigzag trace that shoes the varying amplitude of ground oscillations beneath the instrument.

- The seismometers detect the motion and send a signal to the seismograph to be amplified and recorded (2) another to record horizontal east-west waves, and (3) a vertical one that records up-down ground motions.

Seismology From Wikipedia, the free encyclopedia. Seismology (/saɪzˈmɒlədʒi/ ; from Greek σεισμός earthquake and -λογία study of) is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies.cholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus (c. 585 BCE), Anaximenes of Miletus (c. 550 BCE), Aristotle (c. 340 BCE) and Zhang Heng (132 CE).

How do seismograms recorded during earthquakes help scientists learn about the composition of the Earth? Answers. Best Answer: Earthquakes generate energy that travels through the earth in the form of seismic waves, much in the way that waves travel through water. Seismographs record the arrival of these seismic waves. The earth is composed of a great variety of materials of different densities and composition.

How does a seismograph work? What is the Richter scale? A big mechanical seismograph may have a weight attached that weighs 1,000 pounds (450 kg) or more, and it drives a set of levers that significantly magnify the pen's motion. Keep Reading Below The Richter scale is a standard scale used to compare earthquakes.

Tsunami Questions A seismograph is an instrument used for recording the intensity and duration of an earthquake. Click Here to calculate the strength of earthquakes! What is a tsunami? A tsunami is a large ocean wave usually caused by an underwater earthquake or a volcanic explosion. Tsunamis are NOT tidal waves. Tidal waves are caused by the forces of the moon, sun, and planets upon the tides, as well as the wind as it moves over the water.

- Seismology is the study of earthquakes and seismic waves that move through and around the earth. A seismologist is a scientist who studies earthquakes and seismic waves. Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. They are the energy that travels through the earth and is recorded on seismographs. Types of Seismic Waves. There are several different kinds of seismic waves, and they all move in different ways.

How Seismographs Work Seismographs can detect quakes that are too small for humans to feel. During an earthquake, ground-shaking seismic waves radiate outward from the quake source, called the epicenter. Different types of seismic waves travel at different speeds and through different parts of the Earth during a quake.

- Magnitudes are based on a logarithmic scale (base 10). What this means is that for each whole number you go up on the magnitude scale, the amplitude of the ground motion recorded by a seismograph goes up ten times.
