Are all volcanoes 100 percent predictable?

Answer 1

yes they can be predicted there are very different ways so it can be be animals if they change there reactions they are predicting a earthquake i know because my geography teacher told me lol

Answer 2

Before a volcano erupts, there will always be warning signs.

Bernard Chouet, a scientist with the US Geological Survey, described last week on the BBC2 programme Horizon how he was able to predict volcanic eruptions by detecting a particular type of tremor in the ground. These "long period events" were sure signs, he said, that pressure was building up inside the volcano.

The BBC flagged this up as a revolutionary technique, but Bill McGuire, director of the Benfield Hazard Research Centre at University College London, says this type of seismic monitoring is standard. "There are lots of different methods of monitoring volcanos now but the two ways that unequivocally tell us that a volcano's getting ready for eruption are still the old ones - earthquake activity and ground deformation," he says.
Before a volcano erupts, magma (molten rock) rises towards the surface, breaking rock en route. As more pushes up, the rocks around it vibrate. This results in earthquakes that can sometimes cause damage to buildings but are nothing like the big tectonic quakes seen on the west coast of the US or recently in Turkey.
Any sudden change in quake activity around an active volcano will, hopefully, give scientists enough time to sound warnings.

The magma also causes ground deformation. "As magma rises into a volcano, it has to make space for itself and that means that the ground has to swell," says McGuire. Every year, his team travels to Mount Etna to measure the relative positions of several reference points using sophisticated GPS recording receivers. Any changes in position - of the order of tens of centimetres - could mean the onset of an eruption.
David Rothery, a researcher in the volcano dynamics group at the Open University, uses another method of detecting potential eruptions. Many volcanos have craters at the summit but it is usually too dangerous to put instruments there. He peers at craters from space using satellites that measure infrared radiation, and looks for any sudden changes in heat activity. He says that, depending on the volcano, scientists will get anything from several months to a few days notice of an eruption.

In theory, then, eruptions shouldn't cause casualties. But this always depends on the evacuation plans for danger areas. Before Vesuvius erupts again, for example, 600,000 people will have to be evacuated, possibly at only a couple of weeks' notice. "It's a matter of political will, it doesn't come down to the science in the end," says McGuire.

Answer 3

Yes it can. if you were to monitor the volcano then you will see what it's currently doing and if it shows signs of eruptions it's because of the activity going on with the magma and volcano. Hope this helped!

Answer 4

Geologists can fairly accurately measure a volcano's activity, pressure build-up etc. Many volcanos that are labelled as 'active' now have permanent monitoring stations in the neighborhood that warn if the pressure starts to build up beyond a 'safe' level. The chances of a vulcano erupting in the very near future can now be fairly precisely predicted and today you often read when a vulcano erupts somewhere, that the population living nearby already had been evacuated.

Answer 5

Volcanoes are largely unpredictable due to their nature. Some signs are given prior to eruption but it cannot be precisely predicted.

Answer 6

with the tech we have these days probably about 98.7 are predicted

Answer 7

because its lava erupts when it wants too
