Underwater Data Back Up Theory of Hawaii’s Origin

It is said that the Hawaiian Islands are a result of the already formed volcanoes which resulted and formed mantle plume. Mantle plume is the “upwelling hot material from deep within the earth.” This is simply a theory that has experienced several negative comments and views toward this theory. One of the factors that could influence this theory is the idea of seismetic imagining. This simply means that the seismic waves that would be traced would settle the matter. The seismic waves travel from the earthquake through the mantle that is below the island of Hawaii. Although this idea forms of seismetic imaging, it is quite hard to place this device under or around the state of Hawaii. Instead, the network of recoverable seismeters are arranged on the ocean floor. With the help from both the seismeters on the ocean floor and on the island itself, it can be said that there is a matle plume on the ocean floor right below the island of Hawaii. It was discovered that it is nearly nine hundred miles into the mantle. Another way to discover this idea of mantle plume, was the scheme of shear waves. These are waves that travel slower off the earthquake, traveling through parts of the mantle. The images that they were able to see were three-dimensional figures of the mantle. The images that were found completely support the data and ideas of the plumes that are found in the lower mantle.

Hawaii’s origin, which is partly formed from volcanoes, has formed a trail in the mantle. The volcanoes are one of the features that occur around the plate boundaries and plate tectonics. The mantle plume has an unusual amount of hot rock within the mantle itself. These mantle plumes are the cause of volcanoes, more or less called hotspots. Hotspots are one of the reasons for the development of the Hawaiian Islands. The mantle plume theory discussed has supported evidence from the Hawaiian-Emperor seamount chain, which deals with the idea of the Hawaiian Islands. They were formed through these seamount chains, which is a underwater mountainous region.
