Haleakalā: The Volcano

I drove to the top of Haleakalā. It is 10,023 feet high. The Hawaiian Islands are the tops of volcanoes that grew from the ocean floor. Haleakalā is located on Maui, one of the biggest volcanoes in the world. The “crater” was actually formed by erosion. Most of the volcanoes on the Hawaiian Islands are shield volcanoes, unlike Japan and South America, which are composite.

    When was the last time that Haleakala erupted? Could it still erupt today?
    It was so windy up there!
    You should talk about the ua’u
    Haleakala was a really cool mountain
    Could you explain what a shield volcano is?

      Dear Owen,
      The last time Haleakalā erupted was in about 1790 near the town of Mākena. Yes, it still could erupt. It is even classified as an active volcano. Shield volcanoes pump out lava slowly.

    Ethan – What are the 3 biggest volcanic eruptions that we know of? Were there any interesting plants or animals way up at 10,023 feet? How do they survive?

      Dear Jay,
      The three biggest eruptions were:Tambora in 1815 and Krakatou 1883 which were both in Indonesia, and Santorini in 1470 in the Mediterranean. The most common plant is the Haleakalā Silversword. A common animal is the ua’u.

    Dear Ethan,
    That is an interesting fact. We have been following the news of the lava flow of Mount Kilauea on the big island of Hawaii. It is interesting that it has changed directions after so many years and it now flowing in the direction of the town. I wonder why? Do you know what kind of volcanoes are here in Oregon?

      Dear Mrs. Amri,
      Oregon has all 4 types of volcanoes. Some examples are Mount Hood and Crater Lake, which are composite.
      From, Ethan
