Well in my Holt Science and Technology textbook it says: They study the gases coming from active volcanoes and look for slight changes in the volicano's shape that could indicate than an eruption is near. If this is your directed reading homework. Next time try looking up the answers! all though sometimes i'm lazy too and don't feel like looking it up. Good Luck!

What are two factors scientists monitor that could indicate a volcano night erupt?
magma
What are two factors scientists monitor that could indicate a volcano might erupt?
s-waves and p-waves
Can you predict the exact day when a current volcano will erupt?
No. Although scientists can monitor signs that a volcano is getting ready to erupt they are nowhere near predicting the day a volcano will erupt. They might not even be able to predict the month or even the year that it will erupt.
What do we monitor about volcanoes to predict eruptions?
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 do gps sensors do for volcanoes?
In terms of volcano monitoring the GPS monitoring sites that can be places anywhere on the volcano are used to monitor specific movements of the mountain. The movements of a volcano can indicate many things about what is going on inside the volcano, for example if two GPS units on opposide sides of the volcano are moving further apart it would indicate the volcano is expanding. This could possibly be an indication of magma forcing its way up into the volcano and can also indicate a potential eruption in the future.

What instruments do scientists use to predict eruptions?
Scientists can not actually predict eruptions precisely, they can only detect changes in the earth that COULD precede an eruption and indeed eruptions could happen that were not predicted at all. They monitor volcanic areas with Seismometers (to detect earthquakes and sounds that may indicate the movement of magma). Monitor the gases and water coming out of volcanic areas to detect changes that could indicate magma is moving and also monitor the changes in level of the Earth's surface in volcanic areas to see if magma at depth is "inflating" the ground. Finally they use satellites to monitor changes in the heat of the ground in volcanoes. They also look at past event to try and determine the character of the volcano. With all this they try and inform officials as to what is happening so that people can be evacuated. Sometimes their predictions are correct and sometimes the volcano does not erupt. The scientists value life so the tend to err on the cautious side, recognising that there is a danger of the "cry wolf too often" effect. The decisions are hard.
How do scientists predict when a volcano will erupt?
They use five clues. 1) Frequency and type of earthquakes associated with the volcano 2) changes in slope 3) changes in gases released 4) changes in the volcano's surface temperature 5)changes in animal's behaviour hope those help ya honey ;) thx they really helped i got an a +
What is a volcano that is sleeping but scientists expect to erupted in the the near future?
Dormant volcano
How do scientists classify mount kilauea?
scientists classify Mount Kilauea as a shield volcano
How can scientists deactivate or stop a volcano?
With a nuclear weapon.
Why are laser beams used to monitor volcanoes?
Because laser beams are pulses of pure light - travelling at a known speed. The equipment times how long the pulses take to bounce back from the volcano - if the time differs from scientists calculations, the volcano has either expanded or shrunk - possibly indicating an imminent eruption.
