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

Scientists can monitor the earthquake activity coming from a volcano as well as monitor how the ground deforms around and in the volcano as magma is pushed towards the surface. The scientists can then take an educated guess as to when the volcano may erupt. For quite volcanoes, scientists can look at the geologic record of volcanic eruptions and again make an educated guess as to when it may erupt again.

scientists can predict volcanic eruptions by using a seismograph. But that is just one method they use.

Usually they use seismograph recorder Based on the variations produced under the core Of the earth they try to figure out the Eruption of volcanoes ect.

Can humans able to predict volcanic?

volcanoes is the natural fenomenom most difficult to predict. That duty belong to the people at the seismic intitutions and seismic observatories. They are called geologists. Volcanologists monitor information from sensors near volcanoes to provide short-term forecasts of possible eruptions or changes in the course of existing eruptions. These sensors detect physical changes such as earthquake activity, shape of the volcano, and the release of volcanic gases.
