well , that is a good question ! About 1,300 has happened in the last 10,000 year. Most of these are shield volcanoes. Shield volcanoes are found under water or and form easily. three quarters ( 3/4 ) of volcanoes are shield volcanoes. SO if you subtract all of the shield volcanoes from the amount of volcanoes that have happened in the last 10,000 years it will come up to 6,000 eruptions in the last 10,000 years. This is not including under water or shield volcanoes. WELL, that's all . BYE ! (:
Approximately 200 volcanoes erupted in 2007. Not all these eruptions were huge and some were ongoing eruptions that have been going on for years.
Krakatau has erupted many times.... it's biggest and most important was in 1883
mt etna first erupted on 1500BC so you do the math its last eruption was in 2008
There are so many but you are most likely talking about Eyjafjallajökull.
Igneous rocks are rocks formed by magma. so the best place to find igneous rocks would be by volcanoes or where a volcano once erupted.

I found a website that listed 8. We have already had 22 in 2008. See this link: http://www.volcano.si.edu/world/find_eruptions.cfm So many volcanoes erupted in the world that nobody knows, they couldn't count how many volcanoes erupted since the beginning of the world

So far, only once.
It is not so much that volcanoes tend to occur on islands as much as many islands are formed by volcanoes. Subduction zones and hot spots often cause volcanoes to develop on the sea floor. Erupted material then piles up to form islands.

With some exceptions, volcanoes are generally not dangerous to people. Your chance of being killed by a volcano is 1 in 80000 over your lifetime, which is far less than your chance of being killed in say a motor vehicle accident (1 in 67). There are also two classifications for inactive volcano's. Volcanoes which have not erupted for a significant amount of time are known as dormant volcanoes. Volcanoes which have not erupted in human history are known as extinct volcanoes. Extinct volcanoes are never expected to erupt again, and are therefore not dangerous unless they have been misclassified. So no, I do not think that all volcanoes whether active or inactive are dangerous. The only dangerous volcanoes are dormant volcanoes that explode suddenly with little or no warning.
because it is a volcano and it nearly erupted because volcanoes that erupt are always shorter than normal

Volcanoes have been erupting on the Earth a very Long time so no one on Earth at this very moment will not know.
