Pu'u O'o lava over Chain of Craters Road |
We recently toured Hawaii Volcanoes National Park and drove
to the end of the Chain of Craters Road where it was covered in lava from Pu’u O’o in 2003.
Pu’u O’o is located on an eastern ridge of Kilauea Volcano that parallels
the southern coast of Puna. Pu’u O’o has been erupting for the past 30
years, since January 1983, sending lava down the southern side of the ridge to
the ocean. The lava has destroyed houses, roads, ancient Hawaiian sites, and beaches from Volcanoes
National Park to Kalapana.

Now the lava from Pu’u O’o is flowing a different direction.
Instead of the usual southern direction down the ridge to the coast, lava
is flowing down the other side of the ridge in a northeastern direction.
In the last few months the lava has flowed 5 miles through a forest
heading towards Puna’s eastern coastline. This new flow has been named
Kahauale’a 2.
Tim Orr at the USGS Hawaiian Volcano Observatory recently
gave a presentation about the Kahauale’a Lava Flow in an “After Dark in the
Park” on January 7. He presented a map with what he called “fuzzy”
predictions of where the lava might flow if the eruption continues.
These
predictions were made using topographic maps and plotting the areas the lava
would likely flow. At the current rate of flow, which stops and
starts, he predicts it will not reach a populated area for a year.
When we visit areas around Hawaii Island covered by lava
flows, we get philosophical about how fleeting buildings, beaches, and forests
can be.
We
hope this flow will not follow the predicted path of destruction.
