SERIOUSLY? well they are dangerous because, its hot lave/magma and it kills what ever is in its path. that is including:
-plants
-people
-houses
-cars
-grass
-animals
-trees
etc..
Volcanoes are also dangerous to aircraft flying near them.
No
Yes.
yes
Yes.
If it erupting then yes.
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.
I think any volcano is potentially dangerous. It was once thought that volcanoes were extinct but now scientist think volcanoes are active or dormant. So any volcanoe could erupt and be dangerous. Some are more likely to than others.

This is called an evacuation, though the term does not just apply to volcanoes.
no in 1902 a man named charles william said all volcanoes are all dangerous
They are not studied as much because they are less dangerous than magmatic volcanoes because there has been hardly any deaths from mud volcanoes.
