Why are the Hawaiian Islands arranged in a straight line?

The Hawaiian Islands are located in the central North Pacific and are the largest secondary archipelago among the Polynesian Islands, with a total of 132 islands.

The word "Hawaii" comes from the Polynesian language. Around the 4th century AD, a group of Polynesians arrived in canoes across the waves and settled here. They named the island "Hawaii", which means "primitive." "Home". The first European to discover the islands was the British navigator Captain James Cook, who landed on the Hawaiian Islands in 1778. In 1898, Hawaii was annexed by the United States and became the 50th state of the United States in 1959.

The unique islands of the Hawaiian Islands have attracted the attention of the world. This archipelago is composed of many islands and sea hills of various sizes, which are all formed by volcanoes. However, now only the southeastern Hawaiian Island in the entire archipelago. There are 5 modern volcanoes on the island, of which only 2 are active: Mauna Loa and Kilauea. The other volcanoes are no longer active.

The volcanoes on Hawaii Island have a flat appearance. It is flat, like a giant shield lying flat on the ground, and the top of the mountain is the crater. When a volcano erupts, a lava lake often appears in the crater. There is a lava lake in the Kilauea crater called "Halimomo", which means eternal. The house of flames covers an area of ??100,000 square meters, and the magma in the lake is more than 10 meters deep.

According to research, most modern volcanoes are either located on the boundaries where the crustal plates converge, or are distributed among the plates. On the separated boundary. The volcanoes in the Hawaiian Islands are located deep inside the Pacific Plate, and the volcanic activity here is very frequent, and the amount of magma emitted by the volcanoes is also amazing.

It is even more magical. Yes, the large and small islands of the Hawaiian Islands are almost aligned in a straight line, and the volcanoes are older from southeast to northwest. The Hawaiian Island at the southeastern end is a modern volcanic island that is only over 70 years old, while the volcanic island at the northwest end is older. But he is over 40 million years old.
