Formation of volcanoes
Sometimes volcanoes arise on person’s eyes. Parikutin's origin
The peasant closed the crack with a stone but the steam went out much stronger. By the end of the day there were started explosions. Volcanic bombs and ashes began to fly out as the heated flow of lava. In a year the mountain grew up to 430 meters height. What was the reason of Parikutin's origin?

There are a lot of volcanoes under the ocean. A volcano top over the water surface forms the volcanic island. E.g., Hawaiian Islands have volcanic origin. Volcanoes of Hawaian Islands, such as Mauna-LoaThere are a lot of volcanoes under the ocean. A volcano top over the water surface forms the volcanic island. E.g., Hawaiian Islands have volcanic origin. Volcanoes of Hawaian Islands, such as Mauna-Loa, Kilauea, are erupted without explosions. In the craters of these volcanoes there are lakes of liquid lava, which is thrown up on the huge height up to 280 meters during the eruption, and then is speeded over slopes. Because of liquid lava's outpouring, these volcanoes have the shield shape that is why they are called shield-shaped volcanoes.

Mauna Loa's most recent eruption occurred from March 24, 1984, to April 15, 1984. No recent eruptions of the volcano have caused fatalities, but eruptions in 1926 and 1950 destroyed villages, and the city of Hilo is partly built on lava flows from the late nineteenth century. In view of the hazards it poses to population centers, Mauna Loa is part of the Decade Volcanoes program, which encourages studies of the most dangerous volcanoes. Mauna Loa has been intensively monitored by the Hawaiian Volcano Observatory (HVO) since 1912. Observations of the atmosphere are undertaken at the Mauna Loa Observatory, and of the Sun at the Mauna Loa Solar Observatory, both located near its summit. Hawaii Volcanoes National Park covers the summit and the southeastern flank of the volcano, including a separate volcano, Kilauea.

Kīlauea is located on Hawai’i Island, Hawai’i, in the United States.
Kilauea is an active volcano in the Hawai’ian Islands, one of five shield volcanoes that together form the Island of Hawai’i. In Hawai’ian, the word kīlauea means "spewing" or "much spreading", in reference to the mountain's frequent outpouring of lava. Issuing lava continuously since January 1983, Kīlauea is currently the most active volcano on the planet, an invaluable resource for volcanologists, and also the planet's most visited active volcano. Kīlauea is the most recent of a series of volcanoes that have created the Hawai’ian Archipelago, as the Pacific Plate has moved and is moving over the Hawai’i hotspot.
