Oahu is one of the eight main islands of the Hawaiian archipelago. She is also The Gathering Place (“The collection point”) called. On Oahu is Honolulu, the capital of the U.S. state of Hawaii. With 1557 square kilometers, Oahu is the third largest of the islands, nearly one million residents make up about 75 percent of the population of the state. Oahu is 64 km long and 42 miles wide and is also the economic center of Hawaii. The coastline of the island is 336 kilometers.
Oahu has two volcanoes, the Waianae and Koolau to which are connected by a wide saddle with one another. Waianae is the remains of an ancient volcano that was situated on the western side of the O’ahu island. It is not a mountain range as such, but the parts of a single shield volcano. The eruption from the volcano decreased almost 3.2 million years ago. Thereafter, the activity of the volcano and the composition of the lava changed. The last eruption is believed to have happened almost 2.5 million years ago. Continuous erosion is still happening and the mountain is becoming smaller with time. The western side has significantly subsided due to erosion while the eastern side is also following the trend due to heavy rainfall and landslides. If you go to my site of choice for an interesting volcanic remnant, it would be Koolau range. It is a natural landmark site and the massive remains of the ancient volcano lie on the western landside as well as extends into the ocean. The highest point of the saddle of Mount Kaala with a height of 1220 meters above sea level. The longest river of the island is Anahulu River. The island is mountainous, reaching the Mount Kaala a height of 1225 meters. Honolulu extends over a large part of Oahu, outside the city are pineapple and sugarcane.
The many popular beaches attract tourists all over the world (mostly Japanese) to, especially the beach of Waikīkī, also known as the “metropolis of the South Seas”, behind which rise the extinct volcanoes Diamond Head and Punchbowl Crater. Alone has 38,000 hotel rooms Waikīkī. Unfortunately the beach was very fitted and it is only a very narrow sandy beach left. The beaches on the west coast around the world Pupukea offer the best conditions for surfing, here are the most important competitions held. Further noteworthy is the Hanauma Bay and the variety of fish.
