Why is Volcanology so important?
Volcanology deals with the formation, distribution, and classification of volcanoes as well as with their structure and the kinds of materials ejected during an eruption (such as pyroclastic flows, lava, dust, ash, and volcanic gases). Since that time volcanology has become an important branch of physical geology.
Why are lava lakes important?
Lava lakes (that differ basically from temporary lava ponds or lava pools) are of great significance because they allow close observations of important phenomena accompa- nying volcanic eruptions that cannot be studied on ‘normal’ volcanoes: dormant ones simply do not manifest these phenomena and erupting ones usually …

Who was the first person to study volcanoes?
Early History The eruption cemented Mount Vesuvius’ place in history as one of the most destructive volcanoes in history and started the science, with the detailed description by Pliny the Younger. The early history of volcanology was dependent on eyewitness accounts and written history of the time.
Is magma hot or cold?
Magma is extremely hot—between 700° and 1,300° Celsius (1,292° and 2,372° Fahrenheit). This heat makes magma a very fluid and dynamic substance, able to create new landforms and engage physical and chemical transformations in a variety of different environments.
Can a volcano erupt underwater?
More than 70 percent of all volcanic eruptions occur underwater and scientists are in the dark when it comes to understanding underwater volcanoes because the eruptions are cloaked from view by thousands of feet of water.
Who is the founder of Volcano?
Etymology. The word volcano is derived from the name of Vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn comes from Vulcan, the god of fire in Roman mythology. The study of volcanoes is called volcanology, sometimes spelled vulcanology.
