... Kilauea is the most active of the 5 volcanoes that together form the island of Hawai’i. It formed underwater between 300,000 and 600,000 years ago and first emerged above the surface of the Pacific Ocean about 100,000 years ago. It is the second youngest volcano formed by the Hawaiian hotspot. It is ...

Shield Volcanoes Composite Volcanoes Cinder Cone Volcanoes
... Cinder cone volcanoes are smaller than shield volcanoes and composite volcanoes. If the eruption contains thick magma, the gas pressure shatters the rock within the volcano into small pieces. In other cases, the lava in the air may harden and fall as fragments. These small pieces are called cinders. ...
