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.
Who discovered the first volcano?
The oldest volcano is probably Etna and that is about 350,000 years old. Most of the active volcanoes that we know about seem to be less than 100,000 years old.
Who discovered volcanoes on Earth?
Its volcanic activity was discovered in 1979 by Voyager 1 imaging scientist Linda Morabito. Observations of Io by passing spacecraft (the Voyagers, Galileo, Cassini, and New Horizons) and Earth-based astronomers have revealed more than 150 active volcanoes.
What created volcanoes?
On land, volcanoes form when one tectonic plate moves under another. Usually a thin, heavy oceanic plate subducts, or moves under, a thicker continental plate. When this happens, the ocean plate sinks into the mantle.
What is the most powerful volcano in the world?
The explosion of Mount Tambora is the largest ever recorded by humans, ranking a 7 (or “super-colossal”) on the Volcanic Explosivity Index, the second-highest rating in the index.
What is the deadliest volcano?
Which volcanic eruptions were the deadliest?
|Mount St. Helens, Washington||1980||573|
|Lassen Peak, California||1915||04|
|Mount Vesuvius, Italy||79 A.D.||3,3602|
Which is the youngest volcano in the world?
|Age of rock||1941–1952|
|Mountain type||Cinder cone|
|Volcanic arc/belt||Trans-Mexican Volcanic Belt|
|Last eruption||1943 to 1952|
What are 5 facts about volcanoes?
Check out these 10 facts about volcanoes…
- Volcanoes are openings of the Earth’s surface.
- The word volcano comes from the word ‘vulcan’.
- Volcanoes can be active, dormant or extinct.
- The liquid inside the volcano is called magma.
- Lava is the liquid that is expelled from the volcano.
- Lava is very, very hot!
How hot is lava?
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).
Who was the first person to discover volcanoes?
While it is not possible to know who first discovered volcanoes, the earliest record of a volcanic eruption was written by Roman author Pliny the Younger. He described the 79 A.D. eruption of Mount Vesuvius in such detail that geologists refer to large volcanic eruptions as “Plinian” in his honor.
When was the Volcanic Explosivity Index ( VEI ) invented?
Volcanoes have a similar scale called the Volcanic Explosivity Index (VEI). The scale was invented by Chris Newhall of the U.S. Geological Survey and Stephen Self of the University of Hawaii in 1982. The Volcanic Explosivity Index gives us a way to measure the relative explosiveness of volcanic eruptions.
Where does the science of Volcanology come from?
Volcanology (also spelled vulcanology) is the study of volcanoes, lava, magma and related geological, geophysical and geochemical phenomena ( volcanism ). The term volcanology is derived from the Latin word vulcan. Vulcan was the ancient Roman god of fire.
Where was the first volcanological observatory in the world?
In 1841, the first volcanological observatory, the Vesuvius Observatory, was founded in the Kingdom of the Two Sicilies.
