- Hualalai is a dormant volcano
on the Big Island of Hawaii. The last time it erupted was in
1801, and it could erupt again. Near the Kona airport is a lava
tube that was formed during that eruption. lava tubes are created
when very fluid lava forms an insulating crust on top of the
flow. This keeps the lava from cooling quickly, and therefore
allows it flow great distances. This particular lava tube is
quite large and is very easy to access.
