this all has to do with where the volcano is located. some volcanos are located in places where ther is more activity underneath, and other have not so much activity. the more activity, the more violently the volcano will erupt.

∙ 14y agoA volcano erupts quietly if its magma is low in silica. Low-silica magma has low viscosity and flows easily.

∙ 12y agoBecause the pressure of magma is different in each volcano.
Because of the amount and pressure of gases in the magma tubes of a volcano.

Hope this helped

How many times does a volcano erupt in a century?
Very varied. Some volcanoes erupt almost continuously, others erupt at periods of some hundreds of years.
How many times does volcanoes go off?
It depends on the volcano. Some volcanoes can erupt very often, while others will only erupt once every hundred years.
Are all volcanoes destructive?
Volcanoes are only destructive to people and property when they erupt. Volcanoes can lie dormant for decades before they erupt. The Hawaiian Islands were all formed from eruptions of volcanoes in the ocean.
How often do active volcanoes erupted?
They're all different. Some erupt multiple times a day, some are dead (never erupt) :)
What is the difference between Compare volcanoes that form on land with volcanoes that form in the ocean.?
Land Volcanoes eat lamas and underwater volcanoes eat camals
What type of volcano does and does not erupt?
Active volcanoes erupt. Dormant volcanoes are quiet - but may erupt again some day. Extinct volcanoes have "closed up shop" for good, and will never erupt again.
Why do some volcanoes erupt while others erupt quietly?
This is because of the time of volcano it is and the type of lava it excretes. A steep volcano will erupt with basaltic lava which is runny and can clog at the top. A shield volcano, however is different as the thick lava emitted just glops onward.
Do volcanoes erupt after 10 centuries?
Some do. Most volcanoes will erupt more frequently than that, but some do go 1000 years or more between eruptions.
How many times can an active volcano erupt?
As many as it wants. Some volcanoes erupt often, some infrequently
How many times does a volcano erupt in a century?
Very varied. Some volcanoes erupt almost continuously, others erupt at periods of some hundreds of years.
When a volcano erupts will they erupt again?
Yes. Many volcanoes erupt more than once during their "lifetime." Some volcanoes are hundreds of thousands, even millions of yeas old and erupt periodically.
What causes some volcanos to erupt quietly?
the preasure of the magma is not putting that much preasur
Why do some volcanoes erupt in under water?
because they were formed under the sea so when they erupt the can form tsunamis
Do all volcanos erupt?
no all the volcanoes do not erupt.there are three types of volcanoes extinct,average and active. no because there are dome mountains that do not erupt and they are full of lava and they will erupt in more or less than 300 years.
How many times does volcanoes go off?
It depends on the volcano. Some volcanoes can erupt very often, while others will only erupt once every hundred years.
Are all volcanoes destructive?
Volcanoes are only destructive to people and property when they erupt. Volcanoes can lie dormant for decades before they erupt. The Hawaiian Islands were all formed from eruptions of volcanoes in the ocean.
Do all volcanoes erupt all of the time?
No. Many volcanoes are dormant or inactive.
