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.

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.

Volcano Watch — Campaign season is here! Another way HVO tracks changes on Hawaiian volcanoes
Geodetic surveys measure the change in shape of our volcanoes due to changes in magma supply and storage. The USGS Hawaiian Volcano Observatory (HVO) has a long history of using many different types of instruments and technologies over the decades to detect these changes.

New HVO webcam: [MKcam] Mauna Loa's Summit and Northeast Rift Zone from Mauna Kea
A new USGS Hawaiian Volcano Observatory webcam provides views of Mauna Loa’s summit and Northeast Rift Zone. The webcam view is to the south from its position on the slope of Mauna Kea. Near-live webcam views and a 24-hour animated GIF are available here: https://www.usgs.gov/volcanoes/...
Volcano Watch — What defines an eruption pause?
Kīlauea’s recent volcano alert-level change, from Watch to Advisory, has attracted some attention.
