Halemaumau Crater

A view of Halemaumau Crater and Jaggar Museum in Hawaii Volcanoes National Park

The latest eruption at Kilauea Volcano has recently been declared paused. It was never an especially dramatic eruption, but when I went down a few days after it began (here) the sky was illuminated by the activity. In recent weeks though, the lava lake formed by the eruption crusted over completely and lava from the active vent was also hidden from view.

The photos are two views of Halemaumau Crater, taken before this latest eruption. In the top one, the collapsed floor of the crater is on the left. This is what the new lava lake was filling up. On the ridge, to the right side of the photo, is the low profile of the Jaggar Museum, which was closed after the 2018 eruption and likely won’t reopen.

The bottom photo shows the easternmost edge of Halemaumau Crater, which wasn’t greatly impacted by this eruption or the events of 2018. Consequently, the walls of the crater are quite green and the floor is dotted with plants. These plants are mostly ohia trees, which are among the first plants to grow in lava fields, in part because their roots will tap into lava tubes to find moisture and nutrients.
