Volcanic Eruptions on Jeju Island

Volcanic Eruptions

• Jeju Island is a volcanic island, formed as a result of volcanic activity that began around 2 million years ago.
• The island is home to a total of 368 parasitic volcanoes, including the iconic Hallasan Mountain, which is the highest peak on the island.
• The volcanic eruptions on Jeju Island were primarily effusive, characterized by the flow of lava rather than explosive eruptions.
• The eruptions were likely caused by the movement of the Eurasian tectonic plate, which led to the formation of the island's unique volcanic landscape.

Lava Tubes

• Lava tubes are natural tunnels formed when the surface of a lava flow cools and solidifies, while the molten lava beneath continues to flow.
• Jeju Island is home to numerous lava tubes, many of which are accessible for exploration.
• The lava tubes on Jeju Island are notable for their well-preserved state, with many featuring unique formations such as lava stalactites and stalagmites.
• The most famous lava tube on the island is the Manjanggul Lava Tube, which stretches for over 9 kilometers and features an impressive array of formations.
• The lava tubes provide valuable insights into the geological history of the island and offer a unique glimpse into the island's volcanic past.
