Kīlauea, Hawaii, USA - January 15, 2025 [Note: no sound] A time-lapse video released on January 15, 2025, captures the awe-inspiring power of Episode 4 of the ongoing Kīlauea summit eruption. The video opens with USGS Hawaiian Volcano Observatory geologists collecting tephra falling on Crater Rim Drive, a closed area within Hawaiʻi Volcanoes National Park, as the sound of glassy lava particles tinkling on the road echoes in the background. As the time-lapse progresses, dramatic shots show lava fountains reaching heights of up to 100 meters (328 feet) from the summit. The video also captures the mesmerizing sounds of the vents, likened to the ocean, as molten lava cascades onto the cone surrounding the vent.
