OverviewPlease note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. An asphalt volcano is a rare type of submarine volcano (seamount) first discovered in 2003. Several examples have been found: first, along the coasts of America and Mexico, and, recently, all over the world; a few are still active. Resembling seamounts in structure, they are made entirely of asphalt, and form when natural oil seeps up from the Earth's crust underwater. In 2007, seven more such structures were discovered off the coast of Santa Barbara, California. The largest of these domes lies at a depth of 700 ft (213 m). The structures were larger than a football field and about as tall as a six-story building, all made completely out of asphalt. The unusual features were first noted by Ed Keller on bathymetric surveys conducted in the 1990s, and first viewed by a team led by David Valentine in 2007, utilizing DSV Alvin. Samples were brought up for testing at the university campus and the Woods Hole Oceanographic Institution. Full Product DetailsAuthor: Frederic P. Miller , Agnes F.
