It is impossible to precisely predict when a volcano will erupt or how large that eruption will be. However in attempting to make a prediction, scientists (geologists called vulcanologists) will look at the history of past eruptions to determine how the volcano has behaved in the past, this will tell the scientist roughly how often the volcano erupts and the type/size of these eruptions. If the volcano is considered to be 'active' or dangerous, the scientist will map the volcano determining it shape, and height precisely and install GPS sensors, tilt meters and seismographs on the volcano at strategic positions. These will then be monitored (usually from a remote location as the instruments will be capable of sending in their data by radio).
When the volcano starts to become active, earthquakes will be detected (starting deep and getting shallower and shallower as magma rises up in the volcano's Plumbing). As the magma reaches the upper magma chambers the volcano will inflate (get bigger / higher) and the tilt meters will tilt. When this happens the scientists will issue a warning that the volcano is likely to erupt.
===============================================
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.

Scientists study Volcanoes so, they can predict when they will erupt.
Scientists like Dr. Lopes study volcanoes to better understand their behavior, predict eruptions, and mitigate their hazards to help protect communities living near volcanic regions. Studying volcanoes also contributes to our knowledge of Earth's geology and the processes that shape the planet.
eruptive vent, the location of the eruptive vent, and the character of the eruptive vent, also volume, mass, and height
False. Nobody can prevent a volcanic eruption, though scientists have some ability to predict eruptions.
Scientists study volcanoes and earthquakes to better understand the processes of the Earth's interior and how these events impact the environment and human populations. By studying these natural phenomena, scientists can improve early warning systems, develop strategies for disaster management, and contribute to a greater understanding of the Earth's geological evolution.

Volcanologists are scientists who study and monitor volcanoes. They analyze volcanic activity, predict eruptions, and assess potential hazards to help protect nearby communities.
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...
Yes, scientists use volcanoes to predict earthquake activity, because volcanic and earthquake activity go together. Volcanic eruptions spew out lava whose source is in the magma of the mantle. Earthquakes are caused by heat from the mantle making crustal [or lithospheric or tectonic] plates move.

There are so many reasons why scientists monitor volcanoes. The main objective it to fully understand how they happen and also observe patterns that would aid in predicting volcanoes before they can happen.
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.
Scientists are interested in learning about volcanoes erupting primarily so that they can predict future eruptions. More than 80% of the land today was made by volcanoes. Other reasons scientists might study volcanoes include learning about the different minerals found in the lav, or finding out more about the inside of Earth.
Scientists predict that it will last 155 years.
