Exploring an active volcano

Episode 15

Reading the tiltmeter data it was clear that the pressure was building again, an eruption appearing likely in the next day or two. The last episodes have produced ever higher lava fountains, I expect episode 15 to go even higher and I truly wish to see it when it happens.

Right on schedule the first lava appeared, a little rivulet of lava overflowing the north vent onto the crater floor. If the pattern repeated this would be followed by high lava fountains in the next ten hours or so. Episode 15 was on.

Tomorrow it would be, and as tomorrow was also a holiday for me, Prince Kūhiō Day, I would be free to make another volcano run!!

We are a go.

The same plan… a 2am alarm, hit the road, 4am in the park, hike to the Keanakāko’i viewpoint.

Twin Craters

On the west end of the park is a vast area I had never ventured into, the Kaʻū Desert. This was going to change, the two hikes on the top of the list for this particular stay in the park were Mauna Ulu and the Kaʻū Desert. Having accomplished the prior it was time for the latter.

There are two sets of trailheads to enter the Kaʻu Desert. Several of the trailheads are along Highway 11 on the north side of the area. To avoid leaving my car on the side of the main island belt road I chose to use one of the trailheads along the Hilina Pali Road inside the park. Here one can find the Maunaʻiki Trail leading to Twin Craters.

Mauna Ulu

Mauna Ulu first erupted in May 1969 and would continue for the next five years. In the course of those eruptions lava would occasionally fountain over 1,700ft high while flooding much of the surrounding area, eventually constructing a lava shield nearly 400ft above the original ground level.

In many ways the Mauna Ulu eruption was very similar to the Pu‘u ‘Ō‘ō eruptions that would start a decade later and continue for well over three decades. It is the Pu‘u ‘Ō‘ō eruptions that formed my first memories of Kilauea with television news of homes burning in the Royal Gardens subdivision and visits to the ocean entries at Kalapana. While Pu‘u ‘Ō‘ō remains somewhat remote, Mauna Ulu is far more accessible.
