Best Answer

Before an eruption, magma moves into the area beneath the volcano and collects in a magma chamber, or reservoir. As it comes closer to the surface, the magma releases gases. These events can offer valuable clues about the likelihood of an eruption.

What are some examples of volcanic activity leading up to the eruption?

Some examples of volcanic activity leading up to an eruption include increased seismic activity, such as small earthquakes or tremors, ground deformation or bulging caused by magma movement, increased gas emissions, such as sulfur dioxide, and the appearance of new fissures or vents on the volcano's surface through which magma can escape. These signs can help scientists monitor and predict volcanic eruptions.


What conditions makes it difficult to predict the occurrence of earthquakes?

Earthquakes and volcanic eruptions are extremely hard to predict because of their irregularity. This is due to the butter fly effect. For example, in California there had been a volcanic eruption every 30 years since the start of their records, so they a few years ago when it was scheduled to happen the government spent millions on "earthquake-proofing" the area. Nothing actually happened. The main way to predict earthquakes and volcanic eruptions is to look for patterns in the past but it is really not an accurate or reliable method. Earthquakes are a lot harder to predict as they can happen at any point down a convergent or conservative plate boundary spontaneously, where as with a volcano you can study it and look for signs such as bulges or changes of gas composition in the area that could indicate when it will erupt. However new methods of detection are being tested, the strangest being the use of some animals, snakes the most common, that behave in peculiar ways just before an earthquake. Breakthroughs like these and the use of new technologies, like GPS to monitor irregularities in the the shape of volcanoes, will make the prediction of earthquakes and volcanic eruptions much easier in the future


How can scientists stop a volcano from erupting?

Scientists can Predict eruptions to an extent. Once a volcano shows signs of unrest an elevated alert code can be given although a volcano can go quiet again with no warning. So although they can give a prediction of possible activity time and scale are not always certain


When is mount saint Helens going to explode next?

There is no way of knowing. The timing of volcanic eruptions cannot be predicted accurately, even when a volcano is getting ready to erupt. Currently Mount St Helens is not showing any signs of imminent activity.


When will mount saint helens erupt?

Predicting volcanic eruptions although part of the science of volcanology is the most difficult thing to successfully accomplish. The times between eruptions of volcanoes varies, and does not follow an exact pattern or time frame between eruptions. The only way that scientists have an idea of when a volcano will next erupt is when the volcano starts showing signs of unrest, and than it still depends heavily on what types of unrest the scientists are witnessing.

Can scientist predict when a volcanic eruption?

No. They have found there are signs that can give indications that one may happen.

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...

Are there signs of volcanic activity on Jupiter?

No there is no signs of volcanic activity on Jupiter because Jupiter is a gas giant and has no land masses on which to have a volcano on.


Is it safe to climb the volcano Kilimanjaro?

Somewhat. It is a challenge, as the climate changes considerably from the bottom to the top, and the ground is loose in some areas. It has not shown any signs of volcanic activity in many years, so you would not have to worry about eruptions.

Will Mount Vesuvius erupt soon?

It is not known. Volcanic eruptions are difficult to predict. The last eruption of Mount Vesuvius was in 1944. As of December 2016 Vesuvius is not showing any signs that would be cause for immediate concern.
