About Kilauea Volcano:

  • It is the youngest and most active Hawaiian shield volcano, located on the southern part of the Island of Hawai'i, known as Big Island.
  • It is near-constantly erupting from vents either on its summit (caldera) or on the rift zones.
  • Kilauea has a large summit caldera with a central crater, Halemaumau, which is according to Hawaiian legends the home of the fire goddess Pele.
  • Until 1924, it contained a lava lake.

What is a Shield Volcano?

  • Shield volcanoes are a type of volcano that tend to erupt basalt lava, a type of lava that is very fluid when erupted. 
  • Although shield volcanoes are the largest volcanoes on Earth, they do not form soaring mountains with conical peaks like composite volcanoes. Instead, they are broad volcanoes with gentle slopes.
  • Eruptions at shield volcanoes are only explosive if water somehow gets into the vent, otherwise they are characterized by low-explosivity fountaining that forms cinder cones and spatter cones at the vent.
  • The Hawaiian shield volcanoes are the most famous examples.
