This 24-minute USGS video recounts the eruptive history of HALEMAUMAU and tells the story of KILAUEA Volcano's current summit eruption, from its start in 2008 through today. It begins with a Hawaiian chant that expresses traditional observations of an active lava lake, and describes the formation and continued growth of the summit vent and lava lake. USGS-Hawaiian Volcano Observatory scientists share their insights on the eruption—how they monitor the lava lake, how and why the lake level rises and falls, why explosive events occur, the connection between KILAUEA's ongoing summit and East Rift Zone eruptions, and the impacts of the summit eruption on the Island of HAWAII and beyond.
Events surrounding volcanic eruptions and damaging earthquakes in HAWAII have often been described in journals, letters, and newspapers articles in the English language; however, many Hawaiian-language newspapers were in circulation through all but the earliest decades of the 19th century. Any modern reconstruction of the history of Hawaiian eruptions or earthquakes should take advantage of all available sources, and so we seek to add the Hawaiian-language newspaper articles, journals, stories, and chants to the volcano and earthquake literature. These sources have been used in many recent volcanological studies.
These proceedings are transcripts of oral presentations (illustrated with PowerPoint slides or charts) that were collected during a workshop in which Hawaiians and scientists came together to discuss KILAUEA volcanism. The presentations provide excellent introductions to Pelehonuamea chants, describe approaches to scientific field work that respects Hawaiian values and sacred areas, and discuss the importance of recovering and preserving Hawaiian place names.
Authors Trusdell and Lockwood published Geologic map of the northeast flank of Mauna Loa volcano, Island of Hawai‘i, Hawaii. This map refines knowledge of hazards and risks from Earth's largest active volcano. It encompasses the northeast flank of Mauna Loa from the 10,880-ft elevation to sea level, including the towns of Hilo and Volcano. The map shows the distribution of 105 lava flows from more than 30,000 years B.P. to A.D. 1984.
On March 19, 2008, a new volcanic vent opened in HALEMAUMAU at the summit of KILAUEA. Nine years later, the eruption continues. The vent has grown to a gaping crater that's roughly 195 m by 255 m (about 640 x 840 ft) in size. A lava lake within the vent rises and falls, with spattering on the lake surface sometimes visible from the Jaggar Museum Observation Deck. HVO geologist Matt Patrick recently presented an HAWAII Volcanoes National Park "After Dark in the Park" program about this ongoing eruption.
Volcanic Air Pollution Hazards in Hawaii is an updated fact sheet that provides information on the science of Kīlauea's volcanic air pollution, known as "vog." It also addresses impacts to human health, agriculture, infrastructure, and the environment, and guides readers to relevant resources for living with vog.
Noxious sulfur dioxide gas and other air pollutants emitted from KILAUEA Volcano on the Island of HAWAII react with oxygen, atmospheric moisture, and sunlight to produce volcanic smog (vog) and acid rain. U.S. Geological Survey scientists, along with health professionals and local government officials are working together to better understand vog and to enhance public awareness of this hazard.
Hazards associated with the Kamokuna ocean entry an ongoing concern November 09, 2016
People who venture too close to KILAUEA Volcano's Kamokuna ocean entry—by land or by sea—are at risk from multiple hazards associated with lava flowing into the sea. The white plume formed by the interaction of lava and seawater is a corrosive mixture of super-heated steam, hydrochloric acid, and tiny particles of volcanic glass, all of which should be avoided. Lava deltas (new land formed at the ocean entry) can collapse without warning. Should the lava delta shown here collapse, fragments of molten lava and blocks of hot rock would be thrown both inland and seaward, potentially impacting people on the cliff above the ocean entry and in the boat in front of the delta.
