Photo and Video Chronology – Kīlauea – April 9, 2021

Release Date:

Kīlauea's summit eruption continues on the Island of Hawai‘i; Halema‘uma‘u west vent erupts lava into the lava lake, which was 225 m (738 ft) deep this morning, April 9. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear—monitor the eruption from within the closed area of Hawai‘i Volcanoes National Park with NPS permission.

HVO scientists collect detailed data to assess hazards and understand how the eruption is evolving at Kīlauea's summit, all of which are shared with the National Park Service and emergency managers. Access to this hazardous area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park.

Steaming talus on southern lava lake shoreline

The crusted-over southern shoreline of the lava lake in Halema‘uma‘u at Kīlauea's summit has accumulated talus (rubble) blocks on the surface since it solidified in February. On April 8, 2021, HVO field geologists noted steaming east of the talus (above the rubble in the photo) that was producing hazy viewing conditions. USGS photo by C. Parcheta.
