What is a Hydrothermal Vent. The Havre volcano stretching between 3000 and 4000 feet below sea level experiences a pressure between 92 and 122 times that of sea level which scientists suspect dampened its explosiveness and shaped the various types of lava formations. 5232019 The underwater volcano is enormous rising nearly a half mile 08 kilometers from the ocean floor.
Its the length of a 31-mile 5 km race and lies about 31 miles 50 km off Mayottes eastern. This is what happened to form the Hawaiian islands. Underwater volcanic activity is a constant process that shapes the features of the ocean.
