Recovery of Hawai‘i Volcanoes National Park

Kīlauea summit map
The new park map shows the changes that occurred to Halema‘uma‘u and Kīlauea caldera in 2018.


On the Road to Recovery

In 2018, a new eruption of Kīlauea volcano changed the island of Hawai‘i forever. From May through August, large lava flows covered land southeast of the park destroying over 700 homes and devastating residential areas in the Puna District. At the same time, the summit area of the park was dramatically changed by tens of thousands of earthquakes, towering ash plumes, and a massive collapse of Kīlauea caldera.

Although the eruption has ended, the park faces a challenging road to recovery. Damage to park infrastructure was severe and included wrecked buildings, massive rock falls, collapsed and cracked roads and trails, and numerous breaks to water and sewer lines. Recovery began in August, 2018 with assessment and stabilization of park infrastructure, restoration of utilities, and mitigation of safety issues. Most of Hawai‘i Volcanoes National Park is now open and welcoming thousands of visitors each day as the recovery process continues

USGS - Hawaiian Volcano Observatory: Then and now. It has proven difficult to exactly match past and present views of Kīlauea's summit to show the dramatic changes in the volcanic landscape, but here's our latest attempt. At left is a photo taken on November 28, 2008, with a distinct gas plume rising from the vent that had opened within Halema‘uma‘u about eight months earlier. At right is a photo taken on August 1, 2018, to approximate the 2008 view for comparison.
