Tholeiitic‐alkalic transition at subglacial volcanoes, Tuya region, British Columbia, Canada Tholeiitic‐alkalic transition at subglacial volcanoes, Tuya region, British Columbia, Canada
Ash Mountain, South Tuya, and Tuya Butte are three small basaltic volcanoes in the Stikine volcanic belt of northern British Columbia. The volcanoes rise 700, 500, and 400 m above their bases and are about 3.2, 1.6, and 2.6 km3 in volume, respectively. They began eruptive activity under several hundred meters of overlying glacial ice, or water in an ice‐impounded lake, and undegassed...

Preliminary geologic map of the Mount Hood 30- by 60-minute Quadrangle, Northern Cascade Range, Oregon Preliminary geologic map of the Mount Hood 30- by 60-minute Quadrangle, Northern Cascade Range, Oregon
This map shows the geology of the central and eastern parts of the Cascade Range in northern Oregon. The Quaternary andesitic stratovolcano of Mount Hood dominates the northwest quarter of the quadrangle, but nearly the entire area is underlain by arc-related volcanic and volcaniclastic rocks of the Cascade Range. Most stratigraphic units were emplaced since middle Miocene time, and all...

Images of Kilauea East Rift Zone eruption, 1983-1993 Images of Kilauea East Rift Zone eruption, 1983-1993
This CD-ROM disc contains 475 scanned photographs from the U.S. Geological Survey Hawaii Observatory Library. The collection represents a comprehensive range of the best photographic images of volcanic phenomena for Kilauea's East Rift eruption, which continues as of September 1995. Captions of the images present information on location, geologic feature or process, and date. Short...

Volcanic activity in Alaska: Summary of events and response of the Alaska Volcano Observatory 1994 Volcanic activity in Alaska: Summary of events and response of the Alaska Volcano Observatory 1994
During 1994, the Alaska Volcano Observatory (AVO) responded to eruptions, possible eruptions, or false alarms at nine volcanic centers-- Mount Sanford, Iliamna, the Katmai group, Kupreanof, Mount Veniaminof, Shishaldin, Makushin, Mount Cleveland and Kanaga (table 1). Of these volcanoes, AVO has a real time, continuously recording seismic network only at Iliamna, which is located in the...

Hazardous Phenomena at Volcanoes Hazardous Phenomena at Volcanoes
Volcanoes generate a wide variety of phenomena that can alter the Earth's surface and atmosphere and endanger people and property. While most of the natural hazards illustrated and described in this fact sheet are associated with eruptions, some, like landslides, can occur even when a volcano is quiet. Small events may pose a hazard only within a few miles of a volcano, while large...

Volcanic investigations in the Commonwealth of the Northern Mariana Islands, April to May 1994 Volcanic investigations in the Commonwealth of the Northern Mariana Islands, April to May 1994
A team of U.S. Geological Survey geologists, a seismologist, and technicians gathered new geologic, seismic, and deformation data in the Commonwealth of the Northern Mariana Islands (CNMI). Nine volcanic islands on the active East Mariana Ridge north of Saipan were examined between April 20 and May 3, 1994. In addition, a new radio-telemetry seismic station was installed on the island of...

Geochemical data of fumarolically altered rocks, Valley of Ten Thousand Smokes, Alaska Geochemical data of fumarolically altered rocks, Valley of Ten Thousand Smokes, Alaska
Samples from a fossil fumarole originating in the 1912 ash-flow tuffin the Valley of Ten Thousand Smokes have been analyzed to ascertain chemical changes resulting from high-temperature fumarolic alteration and subsequent cooling and weathering of the protolith. Samples of the underlying, dominantly leached, dacite-rich portion of the ash-flow tuff adjacent to the fumarolic conduit and...
