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.

Can scientists predict volcanic eruptions?
Yes, scientists can predict volcanic eruptions, but only to a certain extent of accuracy. One method is to use earthquakes. Earthquakes usually increase and become more violent before a volcanic eruption
What three methods do scientist's use to predict volcanic eruptions?
Four clues that scientists use to predict eruptions are... -studying dormant volcanoes -monitoring small earthquakes that occur before the eruption -studying the ratio of gases collected -studying active volcanoes
When can scientists predict the next big earthquake?
they use a radar and they use it to find earthquakes. might not be right but sorry tried
What other instruments might an amateur meteorologist use to help predict the weather?
anemometer to measure the wind speed
Mendeleev's periodic table was use ful because it enabled scientists to predict properties of unknown?
elements

Do scientists use volcanoes to predict earthquakes?
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.
What instruments do scientists use to predict tornadoes?
For long-term outlooks, scientists use computer models to predict the behavior of weather systems. This can predict the general risk for tornadoes across a region, but not wehat specific areas will likely be hit. On the short term, the rotation in a storm that may produce a tornado is detected using Doppler radar. The radar may also detect the tornado itself.

Do scientists use satellite data to predict earthquakes?
Yes, through the use of global positioning systemsscientists use satellite data to predict earthquakes.
What do scientists predict that polymer products will increase the use of?
Nuclear energy
What do scientists use the Hardy-Weinberg model for?
To predict changes in allel frequency
How do scientists predict tsunami?
they use satellites to see if there is high or low pressure.
What other instruments might an amateur meteorologist use to help predict weather conditions?
they use satellites and barometers and thermometers
