Photo and Video Chronology – Kīlauea – January 22, 2021

Kīlauea's summit eruption continues on the Island of Hawai‘i; the west vent in Halema‘uma‘u erupts lava into the lava lake. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear and PPE—monitor the current eruption from within the closed area of Hawai‘i Volcanoes National Park with NPS permission.

Volcano Watch — A closer look at Kīlauea’s newest lava

Every rock on Earth is made of up a unique combination of chemical elements, and lavas/tephra formed during Hawaiian eruptions are no exception. What is the geochemistry of Kīlauea’s newest tephra—and how can it help us understand the processes driving the ongoing eruption

Volcano Watch — Gas math—how we know how much sulfur dioxide volcanoes emit

Volcanic gases are an important part of eruptions—they help magma to rise within the earth and erupt, they can tell us how much lava is being erupted, and the volcanic air pollution (vog) they cause can be a hazard. So it is important for the USGS Hawaiian Volcano Observatory (HVO) to measure how much of what kind of gas is being emitted by our volcanoes.

New USGS Professional Paper — The 2008–2018 Summit Lava Lake at Kīlauea Volcano, Hawai‘i

Three chapters of USGS Professional Paper 1867, "The 2008–2018 Summit Lava Lake at Kīlauea Volcano, Hawai‘i" were recently published online. The 2008–2018 lava lake at the summit of Kīlauea marked the longest sustained period of lava lake activity at the summit in decades and provided a new opportunity for observing and understanding lava lake behavior.
