Reports of Hearing and Not Hearing the 1992 eruption of Mount Spurr Reports of Hearing and Not Hearing the 1992 eruption of Mount Spurr
Observations of locations where the August 18th, 1992 eruption of Mount Spurr was heard and not heard around Alaska.
Geologic Map of the Summit Region of Kilauea Volcano, Hawaii Geologic Map of the Summit Region of Kilauea Volcano, Hawaii
This report consists of a large map sheet and a pamphlet. The map shows the geology, some photographs, description of map units, and correlation of map units. The pamphlet gives the full text about the geologic map. The area covered by this map includes parts of four U.S. Geological Survey 7.5' topographic quadrangles (Kilauea Crater, Volcano, Ka`u Desert, and Makaopuhi). It encompasses...

The U.S. Geological Survey Volcano Science Center’s response plan for significant volcanic events The U.S. Geological Survey Volcano Science Center’s response plan for significant volcanic events
This publication describes the U.S. Geological Survey Volcano Science Center (VSC) Response Plan for Significant Volcanic Events (hereinafter referred to as “the plan”) that has been developed for U.S volcano observatories over the past several years in consultation with the lead scientist, or Scientist-in-Charge (SIC), of each of the five U.S. Geological Survey (USGS) volcano...

The 2018 eruption of Kīlauea: Insights, puzzles, and opportunities for volcano science The 2018 eruption of Kīlauea: Insights, puzzles, and opportunities for volcano science
The science of volcanology advances disproportionately during exceptionally large or well-observed eruptions. The 2018 eruption of Kīlauea Volcano (Hawai‘i) was its most impactful in centuries, involving an outpouring of more than one cubic kilometer of basalt, a magnitude 7 flank earthquake, and the volcano’s largest summit collapse since at least the nineteenth century. Eruptive...

Geologic map of Okmok Volcano Geologic map of Okmok Volcano
The geologic map and description of map units presented here cover approximately 880 km2 of northeastern Umnak Island, Aleutian Islands, Alaska. This report focuses on Okmok Volcano and its eruptive products and updates the mid-20th-century geologic map of Byers (1959). Mapped deposits reflect the state of the volcano just prior to the 2008 eruption. Published information about other...

Damage assessment for the 2018 lower East Rift Zone lava flows of Kīlauea volcano, Hawaiʻi Damage assessment for the 2018 lower East Rift Zone lava flows of Kīlauea volcano, Hawaiʻi
Cataloguing damage and its correlation with hazard intensity is one of the key components needed to robustly assess future risk and plan for mitigation as it provides important empirical data. Damage assessments following volcanic eruptions have been conducted for buildings and other structures following hazards such as tephra fall, pyroclastic density currents, and lahars. However...

A look ahead to the next decade at US volcano observatories A look ahead to the next decade at US volcano observatories
Volcano monitoring, eruption response, and hazard assessment at volcanoes in the United States of America (US) fall under the mandate of five regional volcano observatories covering 161 active volcanoes. Working in a wide range of volcanic and geographic settings, US observatories must learn from and apply new knowledge and techniques to a great variety of scientific and hazard...

The ~400 yr B.P. eruption of Half Cone, a post-caldera composite cone within Aniakchak caldera, Alaska Peninsula The ~400 yr B.P. eruption of Half Cone, a post-caldera composite cone within Aniakchak caldera, Alaska Peninsula
Aniakchak volcano is a historically active caldera located on the central Alaska Peninsula. The largest eruption from Aniakchak since the ~3,400 yr B.P. caldera-forming eruption occurred ~400 yr B.P. from Half Cone volcano, an intracaldera composite cone on the northwest floor of the Aniakchak caldera that was largely destroyed by the eruption. The ~400 yr B.P. eruption produced a widely...
