A way of classifying volcanoes is by their frequency of eruption. A volcano can be ACTIVE if in the last 10.000 years it´s had some eruption and it has presented signs of activity how gas emissions or earthquakes. Now there are about 500 active volcanoes in the world, the majority along the Pacific 'Ring of Fire'.
If a volcano didn´t present any activity in 10.000 years, this volcano is considerate DORMANT, this doesn´t means that this volcano can be present some eruption in the future.
The last way in wich a volcano can be presented is EXTINCT. Extinct volcano is this that is unlikely to erupt again, because the volcano no longer has a lava supply.

Hi Alex!
In fact, we have a volcano here in Spain in Hierro island which is recently in the news, can you give us any more information about the kind of volcano it is. Thank you for your explanation
The Hierro volcano island is Vulcaniano. The Hierro is the youngest island and is the island with the highest density of volcanoes in the Canary Islands, it has got more than 500 craters. The only knew documented eruption in the Hierro Island was the Black Spine located in Playa Verodal that erupted in 1793 along with a strong earthquake but now there are a new volcano in the sea surface that can produce a new surface.
Ok Alex. I was waiting to see if something happened at the end but... still waiting. Hopefully it would be a nice experience for people to see and nothing else.
Thanks for the information
