Kilauea, United States - September 17, 2024

Amid the fiery eruption within the secluded confines of Nāpau Crater at Hawaiʻi Volcanoes National Park, USGS Hawaiian Volcano Observatory geologists embarked on a daring mission. On a recent expedition, they successfully collected a sample of the active lava flow from Kīlauea's middle East Rift Zone, employing a daring technique to preserve its pristine state.

In a display of scientific ingenuity, the team transferred the molten lava into a metal bucket, quenching it rapidly with water. This immediate cooling was crucial to halt the crystallization process, preserving the lava's geochemical composition exactly as it was when it flowed from the earth.

These samples, now being analyzed in the lab, hold the key to understanding the inner workings of Kīlauea's magma chamber and the paths magma takes as it ascends to the surface. Such data are invaluable for predicting future volcanic activity and refining safety measures for the surrounding communities.
