Volcano Watch — Seismicity preceding the 2020 eruption of Kīlauea Volcano
Pele returned to the summit of Kīlauea on the evening of December 20, 2020. Incredible video documents the start of the new eruption in Halema‘uma‘u and the dynamic ongoing activity. There was no significant change that suggested lava would erupt again so rapidly, but there were subtle signs of restless behavior around Kīlauea’s summit in the months prior to the eruption.
Photo and Video Chronology – Kīlauea – March 4, 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.

Organic geochemical investigation of far‐field tsunami deposits of the Kahana Valley, O'ahu, Hawai'i
Far‐field tsunami deposits observed in the Kahana Valley, O'ahu, Hawai'i (USA), were investigated for their organic‐geochemical content. During short high‐energy events, (tsunamis and storms) organic and chemical components are transported with sediment from marine to terrestrial areas. This study investigates the use of anthropogenic based...

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.

Volcanic aquifers of Hawai‘i—Hydrogeology, water budgets, and conceptual models
Hawai‘i’s aquifers have limited capacity to store fresh groundwater because each island is small and surrounded by saltwater. Saltwater also underlies much of the fresh groundwater. Fresh groundwater resources are, therefore, particularly vulnerable to human activity, short-term climate cycles, and long-term climate change. Availability of fresh...

Demand for freshwater on the Island of Maui is expected to grow. To evaluate the availability of fresh groundwater, estimates of groundwater recharge are needed. A water-budget model with a daily computation interval was developed and used to estimate the spatial distribution of recharge on Maui for average climate conditions (1978–2007 rainfall...

Fish die-offs are important signals in tropical marine ecosystems. In 2010, a mass mortality of pufferfish in Hawaii (USA) was dominated by Arothron hispidus showing aberrant neurological behaviors. Using pathology, toxinology, and field surveys, we implicated a series of novel, polar, marine toxins as a likely cause of this mass mortality. Our...

The USGS recently published "Unoccupied Aircraft Systems (UAS) video of the 2018 lower East Rift Zone eruption of Kīlauea Volcano, Hawaii." The Data Release contains UAS footage from the 2018 eruption of Kīlauea Volcano’s lower East Rift Zone, on the Island of Hawai‘i. A subset of the videos collected were used for monitoring the fissure 8 lava channel and for measuring flow velocities.
A new chapter of USGS Professional Paper 1867, "The 2008–2018 Summit Lava Lake at Kīlauea Volcano, Hawai‘i" was 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.
