What is the role of a volcanologist?
A volcanologist, or volcano scientist, is a geologist who focuses on understanding the formation and eruptive activity of volcanoes.
What a volcanologist does and explain why it is important to study volcanoes?
In fact, most of a volcanologists' work is done studying the remains of either dead or dormant volcanoes, or by monitoring currently present volcanoes that may be active or “reawakening.” Basically, the goals of volcanology are to understand how and why volcanoes erupt, how to predict eruptions, their impacts on the …
Where do volcanologists study?
In addition to working with the USGS, some volcanologists work in state geologic surveys, especially in states like California, Oregon, and Washington, where volcanoes are plentiful. But probably the largest number of volcanologists teach in university geology departments.
How can scientists volcanologists explore volcanoes?
Scientists use a wide variety of techniques to monitor volcanoes, including seismographic detection of the earthquakes and tremor that almost always precede eruptions, precise measurements of ground deformation that often accompanies the rise of magma, changes in volcanic gas emissions, and changes in gravity and …
How do volcanologists predict volcanic eruptions?
Sensitive tiltmeters and surveying instruments can measure and record the slightest changes, which help volcanologists determine, for example, roughly how deep a magma source is, how fast it is moving, and where on a volcano it might erupt.
How do volcanologists study past volcanic eruptions?
Volcanologists use many different kinds of tools including instruments that detect and record earthquakes (seismometers and seimographs), instruments that measure ground deformation (EDM, Leveling, GPS, tilt), instruments that detect and measure volcanic gases (COSPEC), instruments that determine how much lava is …
How are volcanoes being studied?
Volcanologists look to predict when vents are active or about to erupt. They use seismographic data to register subterranean activity such as magma moving, gas emissions, temperature increases, or surface deformation caused by magma moving through underground conduits.
How do scientists study volcanoes for kids?
They use satellite images, fly over the volcanoes with planes, and may even use robots. Volcanology is a special type of geology that focuses on volcanoes. In order to study volcanoes, a scientist has to have a good understanding of the physical geology of the earth.
What data do volcanologists collect?
Volcanologists use many different kinds of tools including instruments that detect and record earthquakes (seismometers and seimographs), instruments that measure ground deformation (EDM, Leveling, GPS, tilt), instruments that detect and measure volcanic gases (COSPEC), instruments that determine how much lava is …
What instruments do volcanologists use to predict volcanic eruptions?
The seismometer is an established tool for predicting volcanic eruptions and volcanologists sometimes set up dozens of them in areas of frequent volcanic activity such as Hawaii. If there is an eruption scientists can use the seismometer data to calculate its center.
How do they study volcano?
Scientists use a wide variety of techniques to monitor volcanoes, including seismographic detection of the earthquakes and tremor that almost always precede eruptions, precise measurements of ground deformation that often accompanies the rise of magma, changes in volcanic gas emissions, and changes in gravity and …

How do volcanologist and geologist identify the kind of volcano existing in a certain place?
The volcanologist's standard tool is a rock hammer, which is used to chip off and collect samples from rocky outcrops. Volcanologists are looking for igneous rocks so that they can learn more about where these rocks have come from and whether they were formed during a volcanic eruption.
How do geologists study volcanic eruptions?

What is used to measure volcanoes?
Seismographs. Seismographs measure movement in the planet's crust. Volcanic eruptions are closely related to the seismic activities that also cause earthquakes and tremors, so seismographs are also often used to monitor volcanoes.
Does a geologist study volcanoes?
A volcanologist is a geologist who studies the eruptive activity and formation of volcanoes and their current and historic eruptions.
What do scientists study about volcanoes?
Volcanology (or vulcanology) is the study of volcanoes, their formation and historical activity. Geologists who specialize in observing volcanic activity and visiting active sites are known as volcanologists.
