History of Kilauea Volcano & Past Eruptions

Kilauea’s origin is predicted to be in the 300,000-600,000 year range, although it did not emerge past sea level until 50,000-100,000 years ago. Geological surveys and examination of boring holes has revealed that there haven’t been any prolonged periods of inactivity in its history. Studies also show that the past 200 years of its existence are probably typical of its entire history. The volcano is composed mostly of lava flows with local pockets of explosive type eruptions. Kilauea has three particular spots that are susceptible to volcanoes – its summit and two rift zones. The caldera of the volcano has come and gone, while the eruption zones have stayed the same over the years. The most notable past eruptions are:

1924 – The Explosions of Kilauea

This volcano was highlighted by frequent earthquakes, steam-driven explosions and ten-ton rocks being blasted into the air. Before this eruption Kilauea was known as a mild, flowing lava volcano and not as a violent eruption producer. The picture below shows a 10 ton rock that was blasted 1 km from the volcano and its resulting crater.  Fortunately at this time there were no populated areas in the blast area so the economic impact was negligible.




1959/1960 – Summit Eruption & Kapoho Eruption

These eruptions together formed a summit-flank collapse, which experts say is how Kilauea should behave. It expels mass from the inside out the vent, then collapses on itself releasing lava flows. The eruptions damaged Koa-e’ Village and destroyed Kapoho Village, causing . The city was covered in a blanket of pumice and ash and lava flows destroyed buildings and flooded yards. The following pictures show some of the devastation of the city.
