Mauna Kea is a mountain and dormant volcano located on the top of the mountains of Okinai Island، with an elevation of about 4،207 meters (13،802 ft) above sea level.

Most of the mountains are under water. When measured from its oceanic base، Mauna Kea is over 10،000 meters (33،000 ft) tall، making it the tallest mountain in the world. Mauna Kea - like Mauna Loa، Hualalai and Kilauea - is made up of a series of hot spots. Hot spots or hot spots arise in the deep layers of the Earth's atmosphere، where hot magma comes out through reeds to the Earth's surface. In the case of Hawaii، the tectonic movement helped to increase the movement of the crustal layer or the lithosphere، so that a series of volcanoes formed in the middle of the Pacific Ocean over millions of years.

In contrast to the neighboring volcano، which is the active Mauna Loa

 volcano، the Mauna Kea volcano is dormant and is considered a "sleeping"

 volcano. Its age is estimated at about one million years، and the age of one of its oldest rocks is estimated at about 200،000 years، and its last activity was 6،000 to 4،000 years ago، when at least 7 volcanoes were active. This period was preceded by periods of calm of no less than 4،500 years، which makes the current state of calm of the volcano a temporary one.

At the top of Mauna Kea there is an astronomical observatory، which was built by a group of international observatories، which constitute the largest observatory in the world. Among them is the Keck Observatory، which has two mirrors، each with a diameter of 10 meters، and they form two telescopes with the highest observing capacity in the world. Due to the sensitivity of the telescopes to the slightest earthquake، the telescopes are set to monitor the celestial bodies using the 'Pointings' method. Any change in the mountain's position will be interpreted as the beginning of the restoration of its volcanic activity.

Deep drilling has been underway on the volcano since 2002، and by analyzing rock samples extracted from the heart of the volcano، scientists hope to find out what is going on in the depths of the earth.
