Recent eruption of Kiluea Volcano on Big Hawaii Island.

23 December 2020.


According to the US Geological Survey Kilauea volcano within Hawaii Volcanoes National Park on the Big Island has erupted recently after a two year break.

About Kiluea Volcano:

  • Kilauea is the youngest and most active Hawaiian shield volcano, located on the southern part of the Island of Hawai’i, known as Big Island.
    Kilauea volcano is near-constantly erupting from vents either on its summit (caldera) or on the rift zones.
  • At present, Kilauea volcano is still having one of the most long-lived eruptions known on earth, which started in 1983 .
  • The Kilauea volcano was last active in 2018 due to an earthquake.
  • It is the most active of the five volcanoes that form the Island of Hawaii.
  • Structurally, Mt Kilauea has a recently formed Caldera.
  •  Caldera is a hollow structure formed after a volcano erupts large volumes of magma in short period of time. The ground surface then collapses downward into the emptied magma chamber. The collapse leaves a massive depression at the surface.
  • Kilauea is a Shield Volcano. Shield volcano is a type of volcano that is composed of fluid lava. It resembles a warrior shield and thus the name Shield volcano. The lava flow of Shield Volcano is greater than the Strato Volcano.
  • Between 1983 and 2018, Kilauea has erupted continuously.
  •  During the 2018 eruption, around two dozen lava vents erupted simultaneously from the summit.
  • The pit crater formed in the volcano is called Halemaumau.
  • The crater contained a lava lake.
  • Eventually water began to fill in the lake after the volcano began to erupt in multiple other locations.

What is Hawaii Hotspot?

  • It is a volcanic hotspot that is located near the Hawaii Islands.
  • The Hotspots are volcanic regions that are fed by the underlying mantle that is hotter than the surrounding mantle.
  • The position of a hotspot is independent of tectonic plate boundaries.
  • The tectonic plates usually move above the hotspots.
  • Volcanoes are created as the tectonic plates move above the hotspots.

Five Major volcanoes of Hawaii Island:

  • Kohala (Extinct),
  • Mauana Kea (Dormant),
  •  Hualalai (dormant),
  • Mauna Loa (active) and Kilauea (active).
  • The Island of Hawaii is currently growing due to volcanoes Mauna Loa and Kilauea
