Recommended: Significance of Hawaiian Island Plumes

How do hot spots support plumes? Mantle plumes produce hot spots with heat. Gillian R. Foulger (2010), a professor of Geophysics at Durham University, said that the term ‘hot spot’ carries with it the presumptions that the volcanism in question is fed by an unusually hot, highly localized source. Some plumes rise beneath the centers of oceanic plates said Charles, Diane, and Lisa (2010). The mantle plumes start from the mantle which is above the core making the plume rise forming a tail and a head rising to where the lithosphere is located, the head of the plume when it touches the lithosphere forms a volcanic activity that is what we call a hot spot. In this essay, I will talk about how and where plumes and hot spots are form, important …show more content…

Different studies have showed that the mantle plumes and the hot spots have different shapes and size. An evidence that we have that backs up the hot spots and plumes is the Hawaiian Island. The Hawaiian Island it said that its formed right in the middle of an Ocean, the Pacific Ocean, during the time that the Hawaiian Island had formed, there was a lot of studies to do because scientist had no idea of how it could be possible for an island to form in the middle of a plate away from its boundaries. A scientist, Wilson, “suggested in the 1960’s that the convection in the underling mantle produced what we now know as a hot spot, and that the islands arose from the magma poking through the sea flow as the plate moved over the hot spot.” This Hawaiian Island Chain is one of the proofs that we have that show the plate movements over the hot spots where also earthquakes help a lot in the hot spot formation. It is said the Hawaiian hot spot appears to be deep and wide and it’s said that as wide as where it could feed three volcanoes at the same time. Robert and Barbara Decker wrote, “The Hawaiian hot spot, whether of deep or shallow origin, seems to be ide enough to feed three volcanoes at the same time.” But of course, this doesn’t end here, after Wilson’s theory, many scientist questioned

Mauna Loa is the oldest of them, Kilauea is the most active, and Loihi is so young in comparison to the others that it hasn’t even breached the ocean’s surface.

How Did Hawaii Change

866 Words | 4 Pages

Hawaii and its inhabitants changed tremendously after the arrival of Captain Cook in 1778 during his third voyage into the Pacific. About 1,300 years earlier, the Polynesians first settled on the island of Hawaii. The rest of the Hawaiian islands- Kahoolawe, Maui, Lanai, Molokai, Oahu, Kauai, and Niihau- were then settled into 300 years later at about 900 A.D. It was not until the Tahitians arrived that the islands were individually ruled by a high priest and the Hawaiians began to believe in gods and demigods. During this time, social class, the art of hula, and the sport of surfing were created as well as conflicts concerning land division between the ruling chieftains.

The Hawaiian Island Chain

Geology of the Hawaiian Island Chain The chain of Hawaiian Islands formed as the Pacific plate moved over a hot spot in the mantle of the Earth. The plate slowly moves northwestward at a rate of about 32 miles per million years. The northwestern islands are older and generally smaller due to prolonged exposure and erosion. Plate tectonics, types of volcanoes, hot spots, and sea mounts, are all an important part of the geology of the hawaiian island chain.

Yellowstone National Park: Supervolcano In America

859 Words | 4 Pages

Many science organizations have agreed that the probability of another super eruption is a low probability chances are quite slim with estimates being a minimum of 1 in 730,000. Technology has gotten better and scientists are better able to detect a possible eruption before it happens due to the many warnings that would appear. There are some warnings before volcanic eruptions occur such as multiple minor earthquakes, land uplift, gas releases through the many small holes which help relieve pressure. In an article by the NSF which stands for National Science Foundation scientists believe that another eruption wouldn’t occur for another 1-2 million years because based on research of its caldera cluster the volcano is undergoing its dying cycle rather than its ramping up cycle. The foundation states that “by studying the pattern behavior of the cycles and its previous eruptions by examining the rock minerals in the vicinity they’re given better clues to suggest the volcano is on its calm stage”.
