Hawaii Beach Observation

8. The waves of the beaches that I observed were all not very big at the time of my observation. The waves were also not going very fast due to the time that I observed at. The weather at the time was cloudy, and I did not see many people at the beaches because it is early in the morning. I also noticed that some of the beaches in Hawaii have rocks near them, while some are surrounded by different types of sand colors. The colors of the waters at different beaches are also different, some are in lighter colors, while the other ones in darker colors.
9. Hawaii is caused by a “hot spot”, which makes it geologically a unique place. Hawaii is in the middle of the Pacific Plate, which is the largest on Earth. The plate may have moved across the
Lava tube is a natural tunnel that is formed by the flowing lava. It is formed when the lava hardens and flows on the outside.
15. The four types of sand found on Hawaiian beaches are black, green, red, and white sand. They are all different in their compositions because of the ways that they were formed. For example, the black sand is from lava or the erosion of black volcanic rocks, and the red sand is formed from the erosion of a cinder cone.
16. Loihi, the new island that is forming in the Pacific Ocean, and is about 30 kilometers off the coast of the Hawaii Island. It is 969 meters below the sea surface and 3,500 meters above the ocean floor.
17. This new island is forming because the Pacific Plate is moving in a northwest direction, and as it moves toward the “hot spot”, new volcanoes will form, which makes Loihi the “new” volcano.
18. In Hawaiian, Loihi means long, which also describes the shape of this new island being long. It has two curving rift zones in both the north and the south summit, and has a caldera that is about 3.7 kilometers long. We know what the new island looks like because there are scientific equipment that scientists used to map out what Loihi look
It is the volcanic hazard that has the greatest threat to Hawaii and it is also the most common hazard there. Lava flows will form either during nonexplosive activity or explosive eruption. Lava flows will destroy everything that is in its path. It can totally damage everything that it goes through, for example, it can destroy an entire town. Scientists have created a map that divides the five volcanoes in the Hawaiian Island into zones that are ranked based on the possibility of the lava flowing through these zones.
Tsunami A large ocean wave that is caused by earthquakes or eruptions of volcanoes. The word tsunami comes from the Japanese words for wave and harbor. Earthquakes beneath the ocean floor, volcanic eruptions and anything that displace large amount of water can cause tsunami. The effects of tsunami include damage of properties, the death of humans, serious flooding and diseases. The Pacific Tsunami Warning Center can give warnings hours before a tsunami’s arrival in
