Collection of geochemical data from Alaska (AVO) This collection is composed of whole-rock and EPMA tephra glass averages geochemical analyses of rocks from Alaskan volcanoes. Most of the data is from published papers, and some of it is unpublished data from AVO. It is contain analyses for approximately 13,000 samples. Nearly all of the collection is stored in a relational database; the collection is published and searchable at https://avo.alaska.edu/geochem/ Categories: Physical Item; Types: Collection, Map Service, OGC WFS Layer, OGC WMS Layer, OGC WMS Service; Tags: Chemistry, Geochemical Data, Geochemistry, Geological Collection, Tephra, All tags... Volcanic, Volcanic Rocks, Volcanoes, Volcanology, Fewer tags Digital elevation model of Kīlauea Volcano, Hawaiʻi, based on July 2019 airborne lidar surveys The 2018 eruption of Kīlauea Volcano on the Island of Hawaiʻi saw the collapse of a new, nested caldera at the volcano’s summit, and the inundation of 35.5 square kilometers (13.7 square miles) of the lower Puna District with lava. Between May and August, while the summit caldera collapsed, a lava channel extended 11 kilometers (7 miles) from fissure 8 in Leilani Estates to Kapoho Bay, where it formed an approximately 3.5-square-kilometer (1.4-square-mile) lava delta along the coastline. Rapidly-deployed remote sensing techniques were vital in monitoring these events. Following the eruption, the U.S. Geological Survey (USGS) contracted the acquisition of rigorous airborne lidar surveys of Kīlauea Volcano's summit,...

It includes rocks from AVO field projects as well as samples collected by AVO-supported graduate students as part of our efforts to better understand eruptive processes and mitigate eruption hazards. It is estimated that there are about 30,000 samples in this collection. The Alaska Division of Geological and Geophysical Surveys division of AVO has no direct...
