I think the volcano is the most dangerous because it can cause massive forest fires and can cause plants and animals to die An example of a volcano that erupted is Mount St Helens ( May 18th, 1980 ) this volcano did not erupt out of the top of the volcano like most volcanos do, it erupted out of the side of the mountain therefore causing massive destruction of the surrounding areas because most people thought it was going to erupt out of the top of it. The areas around the mountain are barren, there is no plants, trees, etc proveing that this volcano was very destructive.
