4 tons is how many pounds
Is 4 tons greater than 2000 pounds? 1 ton equals 2,000 ...
use autoclaves to imitate the interior of a volcano. simulate volcanic explosions with computer programs. study lava samples. listen to the sounds of the interior of a volcano.
The main purpose of the monitoring is to learn when new magma is rising in the volcano that could lead to an eruption.
The Economic Research Institute estimates that volcanologists average $111,182 a year in 2020 – a relatively high salary when compared to other scientists. However, salaries can range anywhere from $77,818 and $138,104 a year, and some volcanologists can even earn bonuses, depending on the employer and region.
Most employers prefer a degree in geosciences, but a degree in physics, chemistry, biology, math, engineering or computer science are also accepted, along with coursework in geology. Be prepared to take classes that include mineralogy, petrology and structural geology.
noun. the study of volcanoes and volcanic phenomena.
They know when a volcano is about to burst So they can get people out first. The main purpose is to protect So people don’t feel the effect. Volcanologists also study the past, The old eruptions and how long they last. Volcanoes leave lots of deposits behind Made up of residue of all shapes and kinds.
The stronger eruptive types are Pelean eruptions, followed by Plinian eruptions; the strongest eruptions are called “Ultra-Plinian.” Subglacial and phreatic eruptions are defined by their eruptive mechanism, and vary in strength.
Why a dormant volcano is not a dead one. … A dormant volcano is one that is “sleeping” but could awaken in the future, such as Mount Rainier and Mount Fuji. An extinct volcano is “dead” — it hasn’t erupted in the past 10,000 years and is not expected to ever erupt again.
You have to go back to school to get a doctor of philosophy (Ph. D.) degree in geology. This will probably take four to five years of additional study and research after you have completed a B.S.
A geosciences degree is generally preferred by employers, although some geoscientists begin their careers with degrees in environmental science or engineering. Some geoscientist jobs require a masters degree. Geologists are licensed in 31 states.
Skills
Volcanoes are classified as active, dormant, or extinct. … Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future. Inside an active volcano is a chamber in which molten rock, called magma, collects.
Ben Kennedy is an associate professor of Geological Sciences at the University of Canterbury. His work involves physical volcanology and fieldwork, geoscience education, experimental volcanology, interpreting volcano monitoring data, measurements of volcanic rock properties, and calderas and magma plumbing.
Typical activity: “nonexplosive” or weakly explosive
Hawaiian eruptions are typically gentle because their lava is highly fluid and thus tends to flow freely both beneath the surface and upon eruption. In contrast, lava of volcanoes located along plate margins, such as Mount St.
What are some things volcanologists and seismologists look for to detect unrest? Small releases of lava Earthquakes Changes in magma chamber dynamics detected geophysically Increased gas release at the summit Sudden snow melt at the summit Changes in topography such as swelling What would make a slope.
Another way that gas is usually released is out of the top of volcano, which is the main vent for the gas. 0:29:15 – As previously mentioned, measuring gas released from the vent is what they are doing by flying over in the helicopter and also with the robot in the 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 …
David Alexander Johnston (December 18, 1949 – May 18, 1980) was an American United States Geological Survey (USGS) volcanologist who was killed by the 1980 eruption of Mount St. Helens in the U.S. state of Washington.

If the weather is good, volcanologists have the opportunity to put in about a 10-hour day that includes walking, observing, sketching, taking notes, photographing and sampling. Once the data is collected, however, it must be analyzed.
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 …
Nonetheless, the International Association of Volcanology and Chemisty of the Earth’s Interior, which is the main professional organization for volcanologists, currently has around 1500 members from around the world. This includes people from many sub-disciplines that study every aspect of volcanoes.
The temperature of lava flow is usually about 700° to 1,250° Celsius, which is 2,000° Fahrenheit. Deep inside the earth, usually at about 150 kilometers, the temperature is hot enough that some small part of the rocks begins to melt. Once that happens, the magma (molten rock) will rise toward the surface (it floats).
The Philippines sits on a unique tectonic setting ideal to volcanism and earthquake activity. It is situated at the boundaries of two tectonic plates – the Philippine Sea Plate and the Eurasian plate – both of which subduct or dive beneath the archipelago along the deep trenches along its east and west seaboard.
volcanologist
A volcanologist is a geologist who studies the eruptive activity and formation of volcanoes and their current and historic eruptions.
I think most volcanologists would agree that their science began with the detailed description of the AD 79 eruption of Vesuvius by Pliny the Younger. He described the earthquakes before the eruption, the eruption column, air fall, the effects of the eruption on people, pyroclastic flows, and even tsunami.
