Introduction to Volcanoes
A Volcanologist is a geologist person who studies the processes involved in the formation and eruptive activity of volcanoes and their current and historic eruptions.

Volcanologists can't sit around in one place and wait for the volcano to start
erupting. They must travel all over the
world in order to study them.
A volcanologist’s work is simply set
in the Earth's most dangerous
place - VOLCANOES!
What Volcanologists wear
By - Parvathi
Where they work
There are two types of work that
volcanologists undertake on a daily basis.
One is fieldwork: spending a few months of the year camped out by a volcano, spending upwards of ten hours a day examining it.
Other times they're in an office, analysing the
data they've collected or putting together
proposals and funds for further research.
The type of equipment that a volcanologist would wear in the field depends on what they are doing. When they work on a volcano they wear Long Sleeved Shirt to protect from sharp died lava. They might use heavy work gloves if they are working on fresh lava flows and a rock-climbing helmet if working in an area where there is a lot of rock fall. If needed they might wear a fire-retardant flight suit,
a gas mask or a flight helmet.
They get a lot of salary .The starting salary
range is $37,000 to $50,000 per a month
and the highest range of salary is about
100,000 which is quite a rare salary.
David Alexander Johnston
David Alexander Johnston (December 18, 1949 – May 18, 1980) was an American USGS volcanologist who died during the 1980 eruptions of Mount St. Helens in Washington. He was the first to report the eruption, transmitting "Vancouver! Vancouver! This is it!" before he was swept away by a lateral blast.
David Alexander Johnston
Johnston's remains were never found, but state highway
workers discovered remnants of his USGS trailer in 1993. Johnston's career took him across the United States, where he studied Augustine Volcano in Alaska, the San Juan volcanic field in Colorado, and long-extinct volcanoes in Michigan. Johnston was a meticulous and talented scientist, known for his analyses of volcanic gases and their relationship to eruptions.
David Alexander Johnston
His work, and that of fellow USGS scientists convinced authorities to close Mount St. Helens to the public before the 1980 eruption. His story became intertwined within the popular image of volcanic eruptions and their threat to society, and a part of volcanology's history. To date, Johnston, along with Harry Glicken, is one of two American volcanologists known to have died in volcanic eruptions.
