How does the movement of tectonic plates occur? The layer of the Earth called the mantle is continuously circulating like rice would in boiling water. Scientists use a network of satellites called the global positioning system to measure the rate of tectonic plate movement.

- Historically, the classical means for measuring expansion. coefficients has been the “dilatometer”. In this type of. instrument, the difference in expansion between a rod. made from the test material and a matching length of. quartz or vitreous silica is compared1,2. Their differential. expansion is measured with a sensitive dial indicator, or with an electrical displacement transducer.

What instrument measures earth tremors? Geophone is the instrument used for measuring earth tremors!!! By the way, the term geophone derives from the Greek word geo meaning earth and phone meaning sound. A geophone is a device which converts ground movement (displacement) into voltage, which may be recorded at a recording station.

The Science of Earthquakes Earthquakes are recorded by instruments called seismographs. The recording they make is called a seismogram. (figure 4) The seismograph has a base that sets firmly in the ground, and a heavy weight that hangs free. When an earthquake causes the ground to shake, the base of the seismograph shakes too, but the hanging weight does not. Instead the spring or string that it is hanging from absorbs all the movement. The difference in position between the shaking part of the seismograph and the motionless part is what is recorded.

Plate Boundaries Calculating a Rate. 1  To calculate the rate of plate motion, divide the distance the plate moves by the time it takes to move that distance. 2  For example, a plate takes 2 million years to move 156 km. Calculate its rate of motion. 3  Practice Problem The Pacific plate is sliding past the North American plate.

What is a Seismograph? - Definition, History & Facts The Seismograph-Measuring Earthquakes. A 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. 2  The epicenter, which is the location on the surface of the earth below which the earthquake occurred.

How Earthquakes Work The most common standard of measurement for an earthquake is the Richter scale, developed in 1935 by Charles F. Richter of the California Institute of Technology. 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.

Earthquake Glossary seismograph. A seismograph, or seismometer, is an instrument used to detect and record earthquakes. Generally, it consists of a mass attached to a fixed base.During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage.eismograph. A seismograph, or seismometer, is an instrument used to detect and record earthquakes.

How are earthquakes measured? Earthquake magnitudes are measured using seismometers. Based on the amplitude of the seismic waves, seismologists can make a preliminary estimate of the moment and Richter magnitudes of the earthquake. For a more accurate estimate of the energy released, seismologists use the moment magnitude scale (MW).

- Equation (٭). If the motion transducer in the seismic instrument measures the displacement of the mass relative to the base, the output of the transducer is proportional to the acceleration of the transducer base for a specific frequency range and the device is called an accelerometer.

- Geologists place tiltmeters on the sides of volcanoes tomeasure the displacement of the surface as magma moves inside thevolcano. Although most tiltmeters today are electronic, thetraditional tiltmeter, used for decades, consisted of two or morewater-filled metal cans placed some distance apart and connected bya hose.

What are the different scales used to measure the magnitude of earthquakes? How do they differ? The Richter Scale. Figure 1 - Charles Richter studying a seismogram. There are a number of ways to measure the magnitude of an earthquake. The first widely-used method, the Richter scale, was developed by Charles F. Richter in 1934.nother way to measure the strength of an earthquake is to use the Mercalli scale. Invented by Giuseppe Mercalli in 1902, this scale uses the observations of the people who experienced the earthquake to estimate its intensity. The Mercalli scale isn't considered as scientific as the Richter scale, though.

- Hundreds of small earthquakes are caused as magma rises up through cracks in the Earth's crust. Seismometers are used to detect earthquakes. Temperatures around the volcano rise as activity increases. Thermal imaging techniques and satellite cameras can be used to detect heat around a volcano.he higher the sulfur content of these gases, the closer the volcano is to erupting. Gas samples may be taken and chemical sensors used to measure sulfur levels. The techniques available for predicting and monitoring volcanic activity are becoming increasingly accurate.

Earthquake Monitoring The arrival times of the seismic waves at the seismometers, together with the locations of the seismometers and the speed at which the seismic waves travel to the seismometers are all used to determine the location of the earthquake.

Measuring Plate Motion Geodesy, the science of measuring the Earth's shape and positions on it, lets us measure plate motions directly using GPS, the Global Positioning System. This network of satellites is more stable than the Earth's surface, so when a whole continent moves somewhere at a few centimeters per year, GPS can tell.

I need major help with with 9th grade science it's about earth quakes help!!! it's only 4 questions? Tiltmeter: works like a carpenter's level, and measures vertical movement along a fault. Creep meter: Measures movement along a slip-strike fault, so it measures horizontal movement along a fault. Laser ranging device: detects changes in distance to a reflector. Basically, it's a device that bounces beams off a reflector to detect fault movements. GPS satellite system: Uses a network of Earth-orbiting satellites and measures tiny vertical/horizontal movements of markers set u on the opposite sides of a fault.
