Taking a Look at the Ogasawara Archipelago

It is believed that this volcanic area was caused by a localised hot spot within the Pacific plate. A concentration of radioactive elements inside of the mantle may have caused this hot spot to develop. The hot spot is stationary so as the Pacific plate moves over it a line of volcanoes are made. This is more proof that the Earth’s crust is moving as suggested by Wegener.

south Tokyo. It is made up of 161 small islands, and in the northern part of the main island is

The Island of Hawaii sits on (almost in the middle of) the Pacific Plate. The Pacific Plate is a giant jigsaw piece of the Earth’s crust that is slowly moving in a northwesterly direction. It moves about four inches a year. There is a basically stationary hot spot deep within the Earth’s mantle. Heat from this hot spot makes molten lava and rock (magma) that rises through the Pacific Plate and erupts continuously on the ocean floor. After thousands of eruptions and over many many years, an island forms a rocky

Essentially, the key fact that makes the islands of Hawaii so unique and worthy of studying is that nearly the entire mountain range is built entirely by volcanic activity and each island is the top of an enormous volcanic mountain. These exceptional qualities fuel the study of how the islands themselves were created, in order to answer the curiosities behind the composition of some of the most extravagant volcanoes in the world.

The island of Iwo Jima is located in the volcanic islands locate 750 miles south of mainland Japan. The island is small covering an area of only 21km2 consisting of a combination of volcanic rock and limestone. (GSI of Japan, 2015) The topography of the island is unique to many others in the area, it has Mt. Suribachi a volcanic vent dominating the southern portion of the island reaching the islands highest point of elevation at 582ft. (GSI of Japan, 2015) The remained of the island is extremely flat and lacks features which allowed the construction of two airfields on the island. The island continues be raised from volcanic uplift, this uplift beaches

Most Americans have never even heard of the place called Iwo Jima until the year of 1945 began. Iwo Jima is a tiny island in the Pacific Ocean. It is only about 5 miles long and 3 miles wide. It is located about 750 miles south of Japan. Iwo Jima means the “Sulfur Island” in Japanese. The island is formed entirely out of black volcanic rock. The beaches that run along parts of the island are coarse black volcanic sand. In 1945, there were very few small trees and bushes as the landscape. Iwo Jima was a small and dark place that smelled like sulfur. In 1945, it became an important part of the United States history.

Mark Twain once described the Hawaiian Islands as “The loveliest fleet of islands that lies anchored in any ocean”. Hawaii is the most unique of the states of America. To further understand the geography of Hawaii, one must understand how Hawaii was formed, how Hawaii was populated, and understand what Hawaii came to be today.

Out of the six islands that make up Hawaii, the island of Oahu is the third largest and second oldest. Oahu is located in the middle of the Pacific Ocean and plate at a latitude and longitude of 21.4389° N, 158.0001° W (Wikipedia, 2016). The island was created from the pacific plate hot spot, a still active intrusion of magma. A hot spot is a geological feature where hot magma from the inside of the earth leaks out onto the Earth’s crust through cracks in the lithosphere. Once the ejected magma hardens it adds to the surface of the Earth, increasing the land elevation in the area surrounding the hot spot. Over millions of years, the collected cooled magma breaks the surface of the ocean, forming a small island. The islands of Hawaii were all formed from the same hot spot in the center of the pacific. The pacific plate moves in the Northwest direction relative to the North American plate due to typical plate tectonics. While this occurs, the hot spot in the pacific remains in the same place ejecting magma on to the Earth’s surface. The movement of the plate has

The Axial Seamount is an underwater volcano. In the Northeast Pacific, it is actually the most active underwater volcano. The volcano is on top of a divergent plate boundary. This volcano is on the Juan De Fuca ridge and the Pacific Plate. This volcano is one of the best-studied volcanoes along the global mid-ocean ridge (Interactive Oceans).

Currently with japan having so many earthquakes because of its location on 4 plates, we dont really know about volcanic earthquakes but nevertheless it exists.

Waimanalo was created by a catastrophic landslide that happened millions of years ago. We had a caldera that was made of basalt and basalt being so brittle breaks very easily.

Did the BIkinians had a fun time with their lives in Bikini Atoll? Nope, did not. Many Bikinians went through tough times because of the contamination of the air when the nuclear bomb was released in Bikini Atoll. The United States should have never conducted a nuclear bomb test in the Bikini Atoll because this can destroy their environment, the people, and also they were forcing the Bikinians and this was an awful experience. They also tested them vehicles.

The Big Island’s volcanoes are thriving and gigantic. With five volcanoes making up the island, the whole place is covered with cooled lava and even some fresh lava. With cool weather and small towns the place is a perfect paradise. MMS Team 8A went to the Big Island and got to explore Hilo town. Hilo town is a small, old town that has cool weather and neat shops. The group got to hike and see the volcano and the crater. They also went to the Jaggar Museum and saw a volcano and the lava in it. Big Island and Oahu are different because of the volcanoes, weather, and the cities and they are the same because of their location, physical makeup, and their ocean.

In the Northeast Pacific ocean lies Axial Seamount. We only discovered Axial Seamount in the 1970s. Axial Seamount is an underwater volcano 1400, below sea level. It sits on two large rift zones trending about 50 km (31 mi). It is located on the Juan de Fuca Ridge. When it erupts, it produces a mile wide lava flow, and it rises 13 meters (43 ft) so it is thicker.(Wikipedia) It is also one of the youngest volcanoes in the chain of
