Can volcanoes erupt suddenly after years of inactivity
A volcano could be dormant for tens to maybe even hundreds of thousands of years, provided there are some bouts of unrest that suggest it has the potential to erupt again.
Even if the volcano has hot springs, mudpots, even geysers, those are hydrothermal features, not volcanic..
What is the youngest volcano
Alasdair BaverstockAlasdair Baverstock. Mexico is home to the world’s youngest volcano. In the past, its eruptions have scared and displaced the surrounding indigenous communities.
Can a diamond melt in lava
According to Wikipedia, the temperature of lava is between 700 and 1200 °C (973 to 1473 K). The melting point of Diamond at about 100,000 atm is 4200 K, which is much higher than the temperature of lava. So, it is impossible for lava to melt a diamond.

Volcanoes usually have a life of many thousands of years. Once a volcano has begun to erupt, it usually takes about ten years before that particular eruption comes to an end. Sometimes the eruption lasts for hundreds of years.
Can a dead volcano erupt
A dormant volcano is an active volcano that is not erupting, but supposed to erupt again. An extinct volcano has not had an eruption for at least 10,000 years and is not expected to erupt again in a comparable time scale of the future.
Can extinct animals come back to life
This story appears in the April 2013 issue of National Geographic magazine. On July 30, 2003, a team of Spanish and French scientists reversed time. They brought an animal back from extinction, if only to watch it become extinct again. The animal they revived was a kind of wild goat known as a bucardo,or Pyrenean ibex.
Are dormant volcanoes dangerous
Each categorisation has different levels of risk associated with it. For example, extinct volcanoes have almost no danger, but dormant and active ones aren’t so safe (because, again, they may erupt at any time). But, in general, it’s true that even minor volcanic activity can cause dangerous earthquakes and mudslides.
How can you tell if a volcano is going to erupt
How can we tell when a volcano will erupt?An increase in the frequency and intensity of felt earthquakes.Noticeable steaming or fumarolic activity and new or enlarged areas of hot ground.Subtle swelling of the ground surface.Small changes in heat flow.Changes in the composition or relative abundances of fumarolic gases.
Can you drink lava
You actually can drink lava. The problem is, you can only do it once. you’d burn your lips off before it goes down into your system. In the same sense that shoving chopsticks up your nose into your brain is “smelling” them, I guess pouring molten rock into your torso through your mouth is “drinking” it.
What was the first animal to go extinct
The Tecopa pupfish, a native of the hot springs of the Mojave Desert, has the distinction of being the first animal declared extinct under the provisions of the Endangered Species Act of 1973.
Where is Australia’s largest extinct volcano
Heard Island is one of the most remote locations in the world, lying in the Southern Indian Ocean about 4100km from Perth, WA. The landscape is dominated by the massive volcano, which is Australia’s largest volcano, and the largest mountain in Australian territory, towering 500m above Mt Kosciuszko.
Are volcanoes ever really extinct
Generally speaking, you could say that an active volcano is one that is currently erupting, or has erupted in the last 10,000 years. … An extinct volcano is “dead” — it hasn’t erupted in the past 10,000 years and is not expected to ever erupt again.
Do volcanoes die
Millions of years ago, we would have been able to see these volcanoes at the surface. They might have been spewing out lava and ash. But now, they no longer have their source of life. … Eventually, when volcanoes have rafted away from the heat source, they falter and die.
Who found the first volcano
The 79 A.D. eruption of Vesuvius was the first volcanic eruption ever to be described in detail. From 18 miles (30 km) west of the volcano, Pliny the Younger, witnessed the eruption and later recorded his observations in two letters.
What is the largest extinct volcano in the world
Tamu MassifThe world’s biggest volcano has lost its title after scientists discovered it formed via seafloor spreading rather than a single eruption. Tamu Massif is an extinct volcano in the Pacific Ocean, around 1,000 miles east of Japan. It covers an area of 120,000 square miles—roughly the size of New Mexico.
Is Mount Arayat an inactive volcano Why
Mount Arayat is a potentially active or a dormant stratovolcano located in the province of Pampanga on the island of Luzon, Philippines, rising to a height of 1,026 metres (3,366 ft). The volcano has a breached crater on its northwest side with a smaller andesitic dome in the collapse amphitheater.
What makes a volcano active dormant or extinct
Volcanoes are classified as active, dormant, or extinct. Active volcanoes have a recent history of eruptions; they are likely to erupt again. 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.
Has anyone cloned an extinct animal
An extinct animal has been resurrected by cloning for the first time—though the clone died minutes after birth. Findings revealed January 23 in the journal Theriogenology describe the use of frozen skin in 2003 to clone a bucardo, or Pyrenean ibex, a subspecies of Spanish ibex that went extinct in 2000.
Can we bring dinosaurs back to life
While dinosaur bones can survive for millions of years, dinosaur DNA almost certainly does not. But some scientists continue to search for it – just in case. So it looks like cloning a dinosaur is off the table, but an alternate way to recreate the extinct animals would be to reverse-engineer one.
Can a volcano erupt twice
How often do volcanoes erupt? Some small volcanoes only erupt once in their lives, while other volcanoes erupt multiple times. Kilaeua volcano in Hawaii, which has been erupting continuously since 1983, is the world’s most active volcano.

The Taal caldera is largely filled by Lake Taal, whose 267 sq km surface lies only 3 m above sea level. The maximum depth of the lake is 160 m, and contains several eruptive centers submerged beneath the lake. All historic eruptions took place from the 5-km-wide volcanic island in the northern-central part of the lake.
What is the oldest extinct volcano
MeijiThe oldest volcano in the chain is the inactive volcano Meiji, which is 85 million years old. So to answer your original question, volcanoes have been erupting on Earth for at least the last 4 billion years and were undoubtedly more active in the distant past than they are today.
Has anyone died from lava
Most of these deaths were caused by volcanic mudflows in the Philippines, pyroclastic flows in Indonesia, lava flows in the Democratic Republic of Congo and volcanic projectiles in Japan. Last year three tourists died in Italy when they fell into a pit in a volcanic crater. … Such lava flows don’t kill many people.
How do volcanoes die
Volcanoes go dormant because magma from the Earth’s mantle can no longer reach the volcano. For example, in Hawaii, the line of islands are slowly moving to the northwest. … This can also happen when the angle of subduction changes and magma begins to rise through the mantle in a different location.

One person has survived falling into much cooler lava in Tanzania in 2007, according to field reports from the Smithsonian. That lava was less than 1,000 degrees Fahrenheit, though, and the person who survived was still recovering and in pain more than five months later.
