Mauna Loa, the world’s largest active volcano has erupted after 38 years recently.


About the Mauna Loa Volcano

  • Mauna Loa is one of five volcanoes that together make up the Big Island of Hawaii, which is the southernmost island in the Hawaiian archipelago.
  • It’s not the tallest (that title goes to Mauna Kea) but it is the largest and makes up about half of the island’s land mass.
  • It sits immediately north of Kilauea volcano, which is currently erupting from its summit crater.
  • Kilauea is well-known for a 2018 eruption that destroyed 700 homes and sent rivers of lava spreading across farms and into the ocean.
  • Mauna Loa last erupted 38 years ago.
  • In written history, dating to 1843, it has erupted 33 times.


Some famous volcanoes

  • Any volcano that has erupted within the Holocene period (in the last 11,650 years) is considered to be “active” by scientists.
  • Dormant” volcanoes are those active volcanoes which are not in the process of erupting currently, but have the potential to do so in the future.
  • Mauna Loa was a dormant volcano for the last 38 years.
  • Extinct” volcanoes are ones which scientists predict will never face any further volcanic activity.
  • Ben Nevis — The tallest mountain in the UK, is an extinct volcano.
  • Krakatoa, Indonesia — One of the most catastrophic volcanic eruptions ever occurred in Krakatoa in 1883.
  • Mount Vesuvius, Italy — In 79 CE, Mount Vesuvius erupted in one of the deadliest eruptions in European history, killing as many as 16,000 and destroying the town of Pompeii.
  • Mount Fuji, Japan — It last erupted in 1707-1708 and had a devastating effect on the local population.
  • Eyjafjallajökull, Iceland — Sometimes referred to as E15, it is one of the many volcanic features of Iceland. In 2010, a relatively small eruption managed to bring air traffic in Europe to a complete standstill.
  • Kīlauea, Hawaii — Adjacent to the Mauna Loa, this is one of the most active volcanoes on the planet. It has been erupting intermittently since recorded history, with its eruption lasting from 1983 to 2018 being the longest continuous eruption ever recorded.
  • Mount St Helens, USA — Located in Washington State, Mount St. Helens was a major eruption that occurred on May 18, 1980 and it remains the deadliest and most economically destructive volcanic event in U.S. history.
