Best Answer

In order to try to predict a volcanic eruption, scientists monitor the distribution of earthquakes near the volcano, the quantity, temperature, and composition of gas emissions, and look for deformation of the volcano itself. All of these can be used to determine if magma is moving underground, how close it is to the surface, and even how obstructed it is.

What devices monitor volcanoes to predict when they will erupt?

Seismometer


True or false scientists can prevent volcanoes eruptions by carefully monitoring volcanoes?

False. Nobody can prevent a volcanic eruption, though scientists have some ability to predict eruptions.


Can meteorologists predict volcanoes?

The fact of whether or not geologists can measure or predict a valcano is silly each valcano is different and it is of nature thus there is not way to predict what it will do and when it will do it.


Can you predict when volcano?

scientists are almost able to predict volcano eruptions because of all the signs we get that we can compare to what has happened before other volcanoes erupted...


What is the device used to predict volcanoes?

Volcanoes eruptions cannot be predicted; some sign are perhaps an increasing seismic activity, increased release of volcanic gases, increased temperature.


Do shield volcanoes produce quiet eruptions and explosive eruptions?

Shielf volcanoes generally produce "quiet" eruptions. Explosive eruptions are rare.


Name the different types of volcanoes according to their shape?

There are three types of volcanoes which have different shapes and types of eruptions. * Shield Volcanoes - are low and flat and have small, flowing eruptions. * Composite Volcanoes - are a mixture between shield volcanoes and cone volcanoes, their eruptions are explosive. * Cone Volcanoes - are the tallest and largest volcanoes, and they have VERY explosive eruptions.


Which volcanoes have only nonexplosive eruptions?

shield volcanoes.


Do shield volcanoes produce quiet or explosive eruptions?

Eruptions at shield volcanoes are almost always non-explosive.


Where will there be volcano eruptions?

No one can predict.Also, there will be volcano eruptions at volcanoes mostly.


Can you predict when volcanoes occur?

Sort of, before volcanos erupt there is often a lot of detectable seismic activity. Howeer you can have similar seisimc activity without an eruption; and there have been eruptions were there was little seismic activty immediately prior to the event.Seismologists are getting better at predicting eruptions, but they still have a lot of work yet to do.


Volcanoes typically have the most explosive eruptions?

Large explosive eruptions are generally characteristic of stratovolcanoes.
