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.

Monitoring Volcanic Gases Measuring Volcanic Gases. Because volatiles play an important role in the generation, evolution and eruption of magma, it is critical that we use various tools to monitor gases both within and emitted from a volcano.he spectrometer is designed to measure the concentration of sulfur dioxide (SO2) in the volcanic plume that is emitted from the volcano. The device requires a standard, from which to analyze the ultraviolet light absorbed by the SO2 molecules in the plume.

Science 6 The geologist might find ash, cinders and bombs. These eruptions products indicate that an explosive eruption occurred. They could also be evidence of a pyroclastic flow. The rock formed from the magma produced by this eruption would be high in silica content.

Definitions &Translations Seismometers are instruments that measure motions of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources. Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources.

- 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.

What Types of Technology Do Volcanologists Use? Volcanologists also use a device called a spectrometer to measure how the gases being emitted by the volcano affect the light. Based on the light above a gas vent, they can tell if the volcano is emitting hydrogen sulfide or carbon and sulfur.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.

What instrument measures earthquakes? The instrument used to measure earthquakes is called a seismometer, which measures the motions of the ground. The old term for this was a seismograph (where the equipment for measuring and plotting the data was combined unlike in the modern equipment where these functions are separate).

- Since volcanic eruptions are caused by magma (a mixture of liquid rock, crystals, and dissolved gas) expelled onto the Earth's surface, we'll first review the characteristics of magma that we covered previously.hort-term prediction of volcanic eruptions involves monitoring the volcano to determine when magma is approaching the surface and monitoring for precursor events that often signal a forthcoming eruption. 1  Earthquakes-As magma moves toward the surface it usually deforms and fractures rock to generate earthquakes.

How are volcanoes and earthquakes related? These earthquakes are usually too weak to be felt but can be detected and recorded by sensitive instruments. Once the plumbing system of the volcano is open and magma is flowing through it, constant earthquake waves, called harmonic tremor, are recorded (but not felt).

Types of Volcanic Eruptions Volcanic Eruptions. The most common type of volcanic eruption occurs when magma (the term for lava when it is below the Earth's surface) is released from a volcanic vent. Eruptions can be effusive, where lava flows like a thick, sticky liquid, or explosive, where fragmented lava explodes out of a vent.

What Two Scales Are Used to Measure Earthquakes? The Mercalli scale also measures the effects of an earthquake at different locations. The Richter scale calculates the strength of an earthquake based on measurements of the amplitude of the largest wave recorded on a seismometer as well as the distance between the earthquake and the same seismometer. It was developed to measure earthquakes in California.

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.

Types of Volcanic Eruptions Here are some of the most common types of eruptions: In a Hawaiian eruption, fluid basaltic lava is thrown into the air in jets from a vent or line of vents (a fissure) at the summit or on the flank of a volcano.The jets can last for hours or even days, a phenomenon known as fire fountaining. Vulcanian eruption is a short, violent, relatively small explosion of viscous magma (usually andesite, dacite, or rhyolite). This type of eruption results from the fragmentation and explosion of a plug of lava in a volcanic conduit, or from the rupture of a lava dome (viscous lava that piles up over a vent).

- 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.

What instruments detect earthquakes? Report Abuse. 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.

- 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.
