Here, a Hawaiian Volcano Observatory geologist takes images and measurements of lava fountain heights during the ongoing Kīlauea summit eruption on December 31, 2024; the eruption began on December 23 and has continued in episodic pulses. Geologists conduct shifts throughout the week to monitor the eruption and note any changes. On December 31, fountain heights reached approximately 80 feet (25 meters) and lava flows continued to cover the floor of Halemaʻumaʻu crater. Observatory staff wear personal protective equipment such gas masks to protect themselves from volcanic gas emissions that can quickly change with the winds and eruptive activity. USGS photo by H.
