The Black Rock Desert volcanic field in Millard County, Utah, is a cluster of several volcanic features of the Great Basin including Pahvant Butte, The Cinders, and Tabernacle Hill. [1] The field's Ice Springs event was an explosive eruption followed by lava flows that were Utah's most recent volcanic activity (1140–1440 AD).
Wah Wah Springs Caldera is a supervolcanic eruption remnant discovered in 2013 in Utah. It released 5,500 to 5,900 cubic kilometres (1,300 to 1,400 cu mi) of tephra, as the Wah Wah Springs Tuff, about 30.06 million years ago in the early Oligocene. It is the largest of the Indian Peak-Caliente Caldera Complex, and includes flows over 500 m ...
Large volcanic eruptions in the 1980s such as Mount St. Helens raised public awareness about the dangers emanating from volcanic activity. While most fatalities during volcanic eruptions occurred at silicic volcanoes, basaltic eruptions like these that occurred in Utah in the past are also potential sources of danger.
The Marysvale contains a variety of volcanic features, including stratovolcanoes, calderas, lava domes, and cinder cones. The field is an example of intraplate volcanism ; its earlier deposits are thought to be related to Farallon plate subduction , while the later bimodal assemblage (especially the basalts) have been linked to Basin and Range ...
The officials said the explosion, near the Sapphire Pool around 10 a.m. local time Tuesday, ... Hydrothermal explosions like that of today are not a sign of impending volcanic eruptions, and they ...
In October 2006, the United States Geological Survey (USGS) adopted a nationwide alert system for characterizing the level of unrest and eruptive activity at volcanoes. The system is now used by the Alaska Volcano Observatory, the California Volcano Observatory (California and Nevada), the Cascades Volcano Observatory (Washington, Oregon and Idaho), the Hawaiian Volcano Observatory and the ...
