The temperature of rocks in the volcanic cone increase.
Changes in shape of the volcanic cone. Most of the time the cone starts to swell or bulge just before a eruption.
A number of increases in small earthquakes or tremors around a volcano
Emission of gas and steam from a volcano.
active
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.
It is possible for Mount Vesuvius, the volcano that buried Pompeii, to erupt again as it is an active volcano. However, there is currently no imminent threat of an eruption. Scientists monitor the volcano closely to detect any signs of increased activity that could indicate a potential eruption.
False. A dormant volcano is not the same as an inactive volcano. A dormant volcano has not erupted in a long time but still has the potential to erupt again, while an inactive volcano is unlikely to erupt again.
The death of a volcano means that the volcano has become extinct and is no longer showing any signs of activity. This can happen when the volcano runs out of magma to erupt or when the volcanic system becomes inactive. Once a volcano is considered dead, it is unlikely to erupt again.
active
An "active" volcano.

There is no scientific evidence to suggest that Yellowstone will erupt in 2018. The volcano is closely monitored by experts, and any potential eruption would likely be preceded by warning signs.
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.
if an active volcano has recently erupted (like Eyjafjallajokull,) then logically it should erupt again, in this case, but it is physically impossible to predict an eruption unless you are a psychic.

active- or live volcano is one that is erupting or has shown signs that it may erupt in the near future dormant- volcano to awaken in the future and become active extinct- or dead volcano is unlikely to erupt again

They can put up some signs, or symbols such as an example like the typhoons signal...
