Volcano Watch — New Instrument Measures Lava Lake with Laser 

The night sky over Kīlauea summit lit up with the glow of lava Sunday, December 20th, 2020. Deep in the caldera, the gathered lake water was boiled by surging lava. A reddened plume escaped the crater, as lava took its place within Halemaʻumaʻu.

Photo and Video Chronology – Kīlauea – June 14, 2021

Kīlauea's summit is no longer erupting; lava supply to the Halemaʻumaʻu lava lake has ceased and sulfur dioxide emissions have decreased to near pre-eruption background levels. HVO field crews—equipped with specialized safety gear—monitor for new changes from within the closed area of Hawai‘i Volcanoes National Park with NPS permission.

    Low-lying areas of tropical Pacific islands

    Sea level is rising faster than projected in the western Pacific, so understanding how wave-driven coastal flooding will affect inhabited, low-lying islands—most notably, the familiar ring-shaped atolls—as well as the low-elevation areas of high islands in the Pacific Ocean, is critical for decision-makers in protecting infrastructure or relocating resources and people.

    The night sky over Kīlauea summit lit up with the glow of lava Sunday, December 20th, 2020. Deep in the caldera, the gathered lake water was boiled by surging lava. A reddened plume escaped the crater, as lava took its place within Halemaʻumaʻu.

    Kīlauea's summit is no longer erupting; lava supply to the Halemaʻumaʻu lava lake has ceased and sulfur dioxide emissions have decreased to near pre-eruption background levels. HVO field crews—equipped with specialized safety gear—monitor for new changes from within the closed area of Hawai‘i Volcanoes National Park with NPS permission.
