Interview Questions.

Question 1. Tell Me Which Were The Largest Eruptions?

Answer :

The size of volcanic eruptions is decided via the amount of lava emitted. The largest eruption over the last 2 centuries changed into Tambora in Indonesia in 1815.
Large volcanic eruptions are greater frequent than asteroid influences of comparable magnitude.
Question 2. Which Are The Most Active Volcanoes?

Answer :

Many volcanoes have been in continuous eruption for many years. Etna, Stromboli, and Yasur were erupting for loads or heaps of years.

The following 4 volcanoes emit the most lava. Kilauea (Hawaii), Mt Etna (Italy), Piton de l.  A. Fournaise (Réunion), Nyamuragira, (D.R. Congo)

Geo Physics Interview Questions
Question three. Tell Me How Do You Know When A Volcano Cannot Erupt Anymore?

Answer :

When there are not any signs of an active magma chamber below the volcano (no unusual seismic pastime, no volcanic gasses escaping and so forth.), and whilst there hasn't been any activity for a long time span (at least 10,000 years).

Question 4. Tell Me What Are The Most Famous Eruptions?

Answer :

Some volcanic eruptions for the duration of history were significant of their contribution to technological know-how. The following volcanoes were huge for their contribution to know-how about eruptions, or took place near big populations.

Question 5. Tell Me How Do You Think They Have Affected The Solar System The Most?

Answer :

Volcanism is a chief thing on all of the terrestrial planets, so it has had a huge have an effect on in forming the Earth, Mars, and Venus.

Question 6. Tell Me What Is The Largest Volcano You've Studied?

Answer :

Misti is simply over 19,000 ft excessive which is effortlessly the best volcano that I actually have ever studied. However, because it's miles an island and a massive part of the volcano is underneath sea-degree Erebus is the overall biggest volcano that I even have ever studied.

Question 7. Tell Me Which Eruptions Caused The Greatest Fatalities?

Answer :

Volcanic eruptions aren't the most dangerous of herbal screw ups. They reason much less fatalities than earthquakes, hurricanes and famines.

In the past two hundred years, there had been over two hundred,000 deaths in volcanic eruptions. Four causes ended in 91% of the fatalities - 

famine and epidemic disease (30%), pyroclastic flows (27%), lahars (17%), and tsunamis (17%).

Question 8. How Long Do Eruptions Last?

Answer :

It is tons more hard to expect the cease of an eruption than to predict its starting. The desk below gives the period of time that volcanoes erupt. 

Explosive eruptions cease whilst enough decompression is attained to purpose magma chamber fall apart and healing of the initial pressure conditions.

Question nine. Tell Me Has Worldwide Volcanic Activity Been Increasing Recently?

Answer :

We from time to time are being requested if the variety of presently energetic volcanoes and ongoing eruptions, or global volcanic pastime, has been increasing lately. Should we be concerned "globally"
The cutting-edge stage of volcanic hobby is completely regular, at the contrary (if not at the low cease of averages over a long time).
The principal difference is that there is faster and greater records available, in addition to accelerated media insurance and public hobby close to international volcanic activity. This would possibly give the impression that volcanic activity is on the growth (which it is not).
Question 10. Where Is Long Valley Caldera Located?

Answer :

Long Valley Caldera is in imperative jap California, essentially at the metropolis of Mammoth Lakes.

Question 11. Tell Me In Your Opinion, How Have Volcanoes Affected The Earth The Most?

Answer :

volcanoes are chargeable for forming the ecosystem that's pretty vital.

Question 12. Tell Me Where Are The Most Active Volcanoes?

Answer :

Kilauea volcano on Hawaii is the arena's most energetic volcano, observed by Etna in Italy and Piton de la Fournaise on La Réunion island. 

After that, it's miles tough to determine the precise order at the listing, but the following are very close: Stromboli, Merapi, Erta Ale, Ol Doinyo Lengai, Unzen, Yasur, Ambrym, Arenal, Pacaya, Klyuchevsky, Shiveluch, and Erebus.

Question thirteen. Do You Know How Many Volcanoes Erupt Every Year?

Answer :

The volcanic explosivity index is a scale from 1 to eight to degree the magnitude (erupted volume) and intensity 
(eruption column top) of an eruption. 
The VEI is not used to explain eruptions of lava that are non explosive. 
Ancient eruptions are determined by using the extent of deposits. 
Modern eruptions are decided by using the found column height.
Question 14. Tell Me Which Were Largest Eruptions In Past 250 Years?

Answer :

The length of volcanic eruptions is determined through the quantity of lava emitted. The largest eruption during the last 2 centuries turned into Tambora in Indonesia in 1815.

Laki fissure, Iceland 1783
Tambora, Indonesia 1815
Cosiguina, Nicaragua 1835
Askja, Iceland 1875
Krakatau, Indonesia 1883
Tarawera, New Zealand 1886
Santa Maria, Guatemala 1902
Ksudach, Kamchatka 1907
Katmai, Alaska, USA 1912
Agung, Indonesia 1963
St. Helens, USA 1980
El Chichón, Mexico 1982
Pinatubo, Philippines 1991
Chaiten, Chile 2008
Question 15. Tell Me Can Volcanic Eruptions Affect Climate?

Answer :

Large volcanic eruptions can reason global climate change or even be answerable for mass extinctions.
Major eruptions in Kamchatka Peninsula, Russia have a disproportionate  effect on international climate, because of the low troposphere elevation at those latitudes, and the ease of dispersal of ash, aerosol, and gas.
Most mass extinctions over the past 500 million years coincide with eruptions of huge igneous provinces. The Cretaceous-Tertiary extinction become synchronous with the Deccan flood volcanism.
There is a fantastic feedback among glacial variability and atmospheric CO2 concentrations: glaciation increases volcanic eruptions, raises atmospheric
CO2, and reasons greater glaciation. Conversely, waning volcanic hobby at some stage in an interglacial could lead to a reduction in CO2 and the onset of an ice age.
Question 16. Tell Me Which Is The World's Most Beautiful Volcano?

Answer :

The traditional symmetrical volcano cone form is one of the maximum spectacular attractions in nature. Of the world's 1500 energetic volcanoes a few stand out as being surprisingly lovely.
Mt Fuji is Japan is renowned for its beauty. There are several different volcanoes which have an excellent more lovely form.
Kronotsky volcano in Kamchatka is even greater beautiful than Fuji, and Mayon volcano in Philippines is one of the maximum incredible in its form.
Question 17. Which Are The World's Most Dangerous Volcanoes?

Answer :

Classification of the sector's most risky volcanoes is challenge to discuss. Below are indexed a number of the maximum risky volcanoes due to their explosive history and proximity to massive populace centres.

Question 18. Tell Me How Dangerous Are Volcanoes?

Answer :

Volcanoes are normally less dangerous than other herbal dangers along with earthquakes, tsunamis and hurricanes.

Volcanoes have a critical of dangers (e.G. Lava flows, ash fall, pyroclastic flows, weather modifications on a worldwide scale) that relate into one of a kind risks or dangers. The risks when journeying an lively volcano rely on which chance zones of the volcano are visited and for the way lengthy.

Question 19. Do You Know Why Are Volcanoes Called Active Even When There Is No Eruption?

Answer :

An lively volcano is a volcano that has had at least one eruption during the beyond 10,000 years. An active volcano is probably erupting or dormant.
An erupting volcano is an energetic volcano this is having an eruption.
A dormant volcano is an lively volcano that isn't always erupting, however presupposed to erupt again.
An extinct volcano has not had an eruption for at least 10,000 years and is not anticipated to erupt once more in a similar time scale of the destiny.
Question 20. Explain Me What Is A Volcano?

Answer :

The word "volcano" comes from the Roman God of Fire. Also the small volcanic island of Vulcano inside the Aeolian Islands off Sicily, was called after that god. Apparently, this island become pretty energetic in Ancient instances and those believed its crater changed into the chimney of the Vulcanus' forge, where the new lava and ash popping out from the crater have been the seen evidence of his interest to forge weapons for the other gods. 

On Hawai'i, the humans attributed volcanic pastime to the lovely, but capricious and at times negative goddess Pele, who cherished hearth and hated water.

Question 21. Tell Me Who Is A Volcanologist?

Answer :

Volcanologists are specialists who look at volcanoes, whether or not dormant, active or extinct. They observe those volcanoes to determine whilst volcanoes erupt, the way it happens and why eruption occurs.
