A volcano rumbles for approximately 5 minutes and 25.3 seconds before erupting. It then continues to slightly rumble whilst the eruption is going on.

Is Magma found in the ocean?
It can be! There really is no place it can not exist so long as there is volcano to support its existence. There are thousands of volcanos under water!
What is an Atoll formed around?
A long extinct oceanic volcano, when the volcano died the sea floor under it slowly dropper causing the volcano to sink beneath the ocean. As it sank a ring shaped coral reef formed around it and continued growing as the volcanic remnant and the reef on top of it continued sinking. Finally only the reef (and the islands on it) remained visible surrounding a lagoon. No sign of the volcano can be seen on the surface, but sonar scans reveal its remnant as a seamount on the seafloor.
Which type of volcano forms a large cone-shaped mountain from alternating layers of lava flow and volcanic ash?
A volcano that forms very large lava flows and builds itself up that way is known as a shield volcano. This type of volcano may not always erupt from a central summit vent but can have satellite vents (Rift Zones) that will form long channels of lava flows going down the slopes. These volcanoes are often times known as erupting in a very placid style and although can have explosive eruptions are very very rare. A volcano of this type would be either KIlauea or Mauna Loa on the big island of hawaii.
Why do earthquakes usually cause more destruction than volcanoes?
are you asking which is more dangerous because if so volcano's are very dangerous but they don't happen as often as earthquake's. earthquakes would be more dangerous because they happen very often tearing down many home and countries also volcano's are pretty bad as well but there aren't very many of them so the answer would be an earth quake.
How long do you have to stipple dry before you paint it?
a day to make sure
How long do a volcano last?
Depends on the volcano, how big it erupts too.
How do you survive a volcane?
Be a long distance a way from the volcano when it erupts.
What is a volcano that does not erupt called?
It can be called an active, dormant or extinct volcano. An active volcano erupts regularly and frequently, however, it might not erupt at some times. A dormant volcano rarely erupts. Therefore, it does not erupt for most of the time. An extinct volcano does not erupt anymore.
Do volcanoes erupt only once?
Most volcanoes are active for a long time before dieing. So no an average volcano erupts more than once in its lifetime.
How long does it take for a volcano to turn into a mountain?
After it erupts a certain amount of times it will start to form into a mountain
What is the different of active and inactive volcano?
Active Volcano erupts from time to time while a inactive volcano hasn't erupted in a long while and may not erupt in the future again. But your never sure if a volcano is truly inactive or not!
What is volcano that erupts often?
Volcanic activity is classified by how often a volcano erupts. A volcano may be active, intermittent, dormant, or extinct.Active volcanoes erupt constantly.Intermittent volcanoes erupt fairly regularly.Dormant volcanoes are inactive, but not long enough to determine whether they will erupt again or not.Extinct volcanoes have been inactive since the beginning of recorded history.
How long does it take for an volcano to erutp?
It varies from volcano to volcano. The super volcano under Yellowstone National Park erupts an average of once every 600,000 years. Others may erupt once, then go extinct. Others may erupt once a century.
What is a dormant volcano?
A dormant volcano, or a sleeping volcano, is a volcano that has been quiet for a long period of time, but has signs that it will erupt again.A dormant volcano is a volcano that hasn't worked for many yearsA dormant volcano is a volcano that is not currently in the process of erupting.
How long after a volcano erupts does the land become fertile again?
The volcanic dust spread over arable land enriches the soil because it contains minerals.
Can volcanoes extinct?
No. If a volcano erupts then it is not extinct; during its period of inactivity it would have been dormant. To add to this. Two examples are the long-dormant Soufrière Hills volcano on the island of Montserrat, thought to be extinct before activity resumed in 1995 and Fourpeaked Mountain in Alaska, which, before its September 2006 eruption, had not erupted since before 8000 BC and had long been thought to be extinct. I am sure the odds are the same as winning the lottery every year for life.
What are the dangers the Yellowstone National Park volcano poses to the US?
When the volcano erupts, it will destroy most of the North American continent. Its plume of gas and dust will change weather worldwide, causing at least a year long period of cold and snow.
