There is an increase in seismic activity (mini-quakes, vibrations, rumblings), and more smoke and lava spray showing above the crater.

An "active" volcano.

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.
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.
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
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.
It depends, a volcano can erupt once and never erupt again. Or, a volcano can erupt multiple times a day.
Yes. If it doesn't erupt and never has erupted then it is not a volcano.
The Lake Toba super volcano is a dormant volcano and there is currently no indication that it will erupt again in the near future. However, it is monitored closely by scientists for any signs of potential activity.
You're probably thinking of the second, much larger volcano in Iceland that began showing signs that it may be about to erupt after the start of the Eyjafjallajökull eruption. That volcano is named Katla.
