USGS HVO Information Statement — Magnitude-4.5 earthquake northeast of Pāhala, Island of Hawai‘i
The U.S. Geological Survey's Hawaiian Volcano Observatory (HVO) recorded a magnitude-4.5 earthquake located beneath the south part of the Island of Hawai‘i, in the district of Kaʻū, on Thursday, June 17, at 4:32 p.m., HST.
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.

Nearshore water quality and coral health indicators along the west coast of the Island of Hawaiʻi, 2010–2014
Coral reefs worldwide are experiencing rapid degradation in response to climate and land-use change, namely effects of warming sea-surface temperatures, contaminant runoff, and overfishing. Extensive coral bleaching caused by the steady rise of sea-surface temperatures is projected to increase, but our understanding and ability to predict where...

The Value of U.S. Coral Reefs for Risk Reduction
Summary of the report, “Rigorously valuing the role of U.S. coral reefs in coastal hazard risk reduction”
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.

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...
