Eruptions in Volcano Sangay
Recently there has been a severe eruption in Ecuador’s volcano Sangay. After the eruption in Ecuador’s Sangay volcano, the ash clouds that came out of it reached an altitude of 8,500 meters (about 28, 890 ft.) in the sky.
Along with this, the movement has also increased in the world’s largest volcanic Mauna Loa located in the Hawaiian Islands. This volcano has slowly started to blaze and scientists have feared that a volcanic eruption could occur at any time.
Sangay Volcano
- Sangay Volcano is one of the most active volcanoes in the world along with Ecuador. This volcano is formed as a result of the convergence of the Nazca Plate and the South American Plate.
- Sangay is the southernmost, mixed volcano (a volcano composed of alternating layers of lava and ash) located in the northern volcanic region of the Andes. It is 5230 meters high.
- Sangay National Park located in the eastern part of the Andes Mountains in the central part of Ecuador. It is a World Heritage Site.
Mauna Loa Volcano
- Mauna Loa is the largest Shield Volcano in the world.
- Mauna Loa Volcano is located on the island of Hawaii and, it is one of the most active volcanoes in the world.
- It is noteworthy that the island of Hawaii is located in the Pacific Ocean.
Volcano:
- A volcano is a natural hole or crack on the crust through which molten matter, gas or steam, ash, etc. come out of the earth.The molten material inside the earth, which comes out of the volcano, is called Lava.
- It is very hot and red in color. The lava becomes solid and black, which is later known as the volcanic rock. There is so much gas in the lava that it does not come out at once. Bubbles in lava occur due to the release of these gases. When the flow of lava stops, steam is seen evaporating for some time.
- These gases are only helpful in bringing the molten rock up, but it is necessary that there is a weak layer somewhere on the crust, which is broken, torn or pierced, through which Gas helps in making the lava a path upwards.
Types of volcanoes
Generally, volcanoes are classified as follows:
- Active volcanoes
- Dormant volcanoes
- Extinct volcanoes
- Active Volcanoes: Those volcanoes, which are erupted periodically. Some of the active volcanoes in the world include Mauna Loa of the Hawaiian Islands, Etna and Stramboli of Sicily, Vesuvius of Italy, Cotopaxi of Ecuador, Baron Island Volcano of Andaman and Nicobar and Taal Volcano of the Philippines, etc.
- Dormant Volcanoes: Those volcanoes are called dormant volcanoes, which have been calm for years but, there is a possibility of volcanic eruption anytime. The dormant volcanoes of the world include Visuvius of Italy, Fujiyama of Japan, Krakatoa and Indonesia of Indonesia and Narcondam volcano of Andaman and Nicobar etc.
- Extinct volcanoes: Such volcanoes are called extinct volcano, which have been quiet for a long time and have stopped erupting. Some of the dead volcanoes in the world include Popa of Myanmar, Kilimanjaro of Africa, Chimbarajo in South America, Monaco of the Hawaiian Islands, Koh Sultan of Iran, etc.
