Science Chapter 5, lesson 3 How do geologists use seismographic data to make maps of faults? Seismographs detect the reflected seismic waves and geologists use this data to map the length and depth of the fault. Why do geologists collect data on friction along the sides of faults? So they can try to predict the probability of a large earthquake.

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.

Earthquakes: seismology & measurement The study of seismic waves is known as seismology, a word derived from a Greek word meaning to shake.. Seismographs are the instruments which record earthquakes. Scientists use these instruments as their principal tool to study seismic waves. They are very sensitive instruments that can detect, measure and record ground vibrations and their intensities during an earthquake. A seismograph is a simple pendulum.

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.

Earthquake and Seismic Waves Geologists first study data from seismographs, this shows what kinds of seismic waves the earthquake produced and how strong they were-it also helps geologists infer how much movement occurred along the fault and the strength of the rocks that broke when the fault slipped-they use all this info to rate the quake on the m.m.s.

- Most seismographs today are electronic, but a basic seismograph is made of a drum with paper on it, a bar or spring with a hinge at one or both ends, a weight, and a pen. The one end of the bar or spring is bolted to a pole or metal box that is bolted to the ground.

Definitions &Translations 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.

Why can seismographs be useful in predicting volcanic eruptions? Confidence votes 1. because almost aways before eruption there is minor earthquakes that the seismograph will detect and read out An ejecting steam from the top of volcano also predicts an eventual eruption.

Who studies earthquakes? Some geologists specialize as geophysicists, who study the physical properties and processes of the Earth. This field includes seismology, or the study of earthquakes. A person who studies earthquakes is called a seismologist.

The Science of Earthquakes Theseismograph has abase that setsfirmly in the ground, and a heavy weight thathangs free. When an earthquake causes theground to shake, the base of the seismographshakes too, but the hanging weight does not.Instead the spring or string that it is hangingfrom absorbs all the movement.

Monitoring Earthquakes a simple seismograph consists of a heavy weight attached a frame by a spring or wire-a pen connected to the weight rests its point on a drum that can rotate and as it slowly rotates the pen draws a straight line on paper wrapped tightly around the drum.

- A network of seismometers constantly monitors movements of the Earth's crust. When an earthquake occurs, seismic waves travel out from its epicenter, through the crust, and are detected by the seismometers.

- Seismometers (in Greek seismos = earthquake and metero = measure) are used by seismologists to measure and record the size and force of seismic waves.By studying seismic waves, geologists can map the interior of the Earth, and measure and locate earthquakes and other ground motions.est Answer: Seismographs and other kinds of seismometers, generally, although there is a pretty wide variety of those and how they function. The old fashioned kind have a weight suspended pendulum-style that remains stationary, and have a slowly rolling drum or roll of paper (usually) underneath the pendulum.

How does a seismograph work? What is the Richter scale? 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. If you live in a city, you may have noticed that buildings sometimes shake when a big truck or a subway train rolls by.

Seismogram A seismogram being recorded by a seismograph at Weston Observatory in Massachusetts A seismogram is a graph output by a seismograph. It is a record of the ground motion at a measuring station as a function of time. Seismograms typically record motions in three cartesian axes, with the z axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface. The energy measured in a seismogram may result from an earthquake or from some other source, such as an explosion. Seismograms can record lots of things, and record many little waves, called microseisms. Th

- A seismometer is the scientific instrument used to detect earthquakes. Signals received from seismometers are recorded and this allows scientists to calculate the size (amount of energy released) of an earthquake, that is, its magnitude.

With great uncertainty, geologists try to predict the chance of a big quake striking Kansas With great uncertainty, geologists try to predict the chance of a big quake striking Kansas. Lori Lawrence says the foundation of her 1917 home was damaged by the recent earthquakes. Lawrence has become one of the leading organizers for the Kansas chapter of the Sierra Club trying to document local damage from earthquakes.
