It depends on the volcano to determine how long it takes to erupt. Mauna Loa in Hawaii erupts almost all of the time and for a long time. While Mt. Saint Helens in Washington hasn't had a huge eruption in almost 30 years.
From the time when a volcano starts having activity for the first time in years, it may take seconds, weeks, or even months before you actually have an eruption.
What else can I help you with?
Do volcanoes erupt at the end of the year?
Volcanoes can erupt at any time of year.
What are valcanoes that no longer erupt called?
Volcanoes that no longer erupt is called an extinct volcano. An extinct volcano is defined as a volcano that has not had an eruption in at least 10,000 years, and is not expected to erupt again in a comparable time scale of the future.
How long does a specific volcano erupt for?
Volcanoes erupt until their lava is gone or until the pressure beneath the volcano is released. There is no way of knowing ahead of time how long that will take. Some volcanoes blow up once and never again, and then there's Kilauea volcano in Hawaii, which has been erupting since 1983.
What is a volcano that is quiet for a long time but may erupt again?
A volcano that is quiet for a long time but may erupt again is known as a dormant volcano. Dormant volcanoes are inactive for a significant period of time but still have the potential to become active and erupt in the future.
Do all volcanoes take the same amount of time to erupt?
No ... it depends on how big the volcano is and the mass ... so the answer is no.
What volcano that has erupted in a long time and is unlike to erupt again?
Mount Rainer in USA,these are called dormant volcanoes.
What is this answer True or false all volcanoes at some point can erupt even if it was dormant for a long time?
True. All volcanoes have the potential to erupt again, even if they have been dormant for long periods. Dormant volcanoes can become active again due to changes in geological conditions, such as the movement of magma beneath the surface. However, predicting exactly when a dormant volcano will erupt can be challenging.
What time of year do volcano's occur?
Volcanoes can erupt any time of year, there is no volcano season.
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.
Do volcanoes erupt more at night or day?
Volcanoes can erupt at any time, regardless of whether it is day or night. The frequency of eruptions is not directly influenced by the time of day. Eruptions are generally monitored continuously, regardless of the time.
Which are the three types of volcanoes?
Active- it has erupted recently and is expected to erupt again Dormant- hasn't erupted in a long time and is not expected to erupt again Extinct- has never erupted and isn't expected to erupt (aka "mountain")
What season volcanoes erupt?
Seasons are to do with weather and climate. A volcano may erupt anytime not in summer or winter, that is irrelevant. Volcanoes do not erupt in a season, the reason they erupt is due to the build up of magma in the Earth's crust below the place they erupt. Some volcanoes are: extinct, nothing happening for a very long time dormant, they have not erupted for a long time but might become active in 500-1000 years active, they 'dribble or spew' all the time new ones which erupt sometimes after other thermal activity becomes apparent sometimes unexpectedly but usually in an area where there are other volcanoes or thermal activity. An example is the Volcanic Plateau in New Zealand which is part of the Pacific Rim of Fire where many extinct, dormant and active volcanoes are situated.
