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.

- Seismometers-instruments that measure motions of  the ground.   The visual output, either on a monitor or on paper is called a  seismograph   Seismometers are in part used to measure the intensity of  earthquakes. The scale used to measure earthquake intensity is  known as the Modified Mercalli scale.

How do scientists measure earthquakes? It is a measure of the largest seismic wave recorded on a particular kind of seismograph located 100 kilometers (about 62 miles) from the epicenter of the earthquake. Think of a seismograph as a kind of sensitive pendulum that records the shaking of the Earth.

Seismic wave Seismic waves are studied by geophysicists called seismologists. Seismic wave fields are recorded by a seismometer, hydrophone (in water), or accelerometer. The propagation velocity of the waves depends on density and elasticity of the medium.

Earthquakes, Volcanoes and Fold Mountains â JC Geography Notes Earthquakes: 1  The strength or force of an earthquake is measured on a Seismograph. 2  The scale used to describe this force is called the Richter Scale. This scale ranges from 1- 12. 3  People are still unable to predict when earthquakes will occur, but we can predict where the plates meet and could cause an earthquake.

What Types of Technology Do Volcanologists Use? Volcanologists use a device called a tiltmeter to measure tiny changes in the angle of the volcano's slope that might indicate a build-up of gases below the surface that could result in an eruption.These changes are too small to be seen by the eye but can still indicate that an eruption is imminent.he most basic tool used by any volcanologist is a simple rock hammer, used for breaking off samples of igneous rock for laboratory analysis. Other samples are collected from the volcano's core using a drill.

History Once called “Thor’s Heights,” Crown Point is a basalt promontory shaped by the same volcanic lava flows, floods and winds that created the Columbia River Gorge. Cited for its “exceptional value in illustrating the natural history of the U.S.,” it was designated as a National Natural Landmark in 1971.

Volcano Monitoring with Tiltmeters and GPS (Educational) Volcano deformation can provide clues about what is happening deep below the surface. Two techniques used to monitor deformation include Tiltmeters and GPS. Like a carpenters level, an electronic tiltmeter uses a small container filled with a conducting fluid and a bubble to measure a change in slope.

Measuring earthquake magnitude and intensity Earthquakes can be measured in two ways. One method is based on magnitude—the amount of energy released at the earthquake source. The other is based on intensity—how much the ground shakes at a specific location. Although several scales have been developed over the years, the two commonly used today in the United States are the moment magnitude scale, which measures magnitude (M), or size, and the Modified Mercalli scale, which measures intensity.

- Definition. A seismograph, also sometimes called a seismometer, is an instrument that measures and records the seismic waves that move through the earth as the result of an earthquake. modern seismograph is a sophisticated instrument that can help scientists detect earthquakes and measure several aspects of the event: 1  The time at which the earthquake occurred.

How do scientists measure earthquakes? With a really big ruler? No, not quite. There are two ways in which scientists quantify the size of earthquakes: magnitude and intensity. You have probably heard of the Richter scale which is still used for small earthquakes, but most large earthquakes are now commonly reported using the moment magnitude scale (see below). Richter scale

- The USGS maintains a variety of fault and volcano monitoring instruments around the western United States, including Hawaii. The data from all instruments are transmitted in real time to the USGS in Menlo Park using satellite, radio and telephone telemetry.easurements can be made to better than 0.1 millibar. Strainmeters for continuous crustal strain monitoring are highly sensitive instruments with precision of less than 1 part per billion (i.e. less than 1 inch in 16,000 miles). They are usually installed in boreholes where surface noise is greatly reduced.

Measuring Earthquakes The Richter Scale, named after Dr. Charles F. Richter of the California Institute of Technology, is the best known scale for measuring the magnitude of earthquakes. The scale is logarithmic so that a recording of 7, for example, indicates a disturbance with ground motion 10 times as large as a recording of 6.

- 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.

Measuring Earthquakes Measuring Earthquakes. The recent earthquake that hit northeastern Japan was measured at 9.0 on the Moment Magnitude Scale (MMS). Scientists known as seismologists use the MMS to determine the magnitude (strength) of an earthquake. The MMS measures the total energy of an earthquake, called the seismic moment.
