Vent Sites      

 

 

 There have been numerous discoveries found on the East Pacific Rise, an underwater mountain range about 500 miles southwest of Acapulco and particularly close to the Galapagos Islands.

These vents are normally found along the crest of mid ocean ridge, a 46,000 mile long chain of mountains that wraps around the earth. They tend to form in linear zones a few kilometers long by a few hundred meters wide. A few vents have also been found at seamounts (Seamounts are isolated submarine elevations of at least 700m of volcanic origins). Hydrothermal vents are normally found at depths of greater than one mile.
