The Geology Behind Italy’s Catastrophic Quake

At least 73 people died in the mountains of central Italy this morning when a magnitude 6.2 earthquake and a series of at least 40 aftershocks shook the Umbria, Lazio and Marche regions.


State geologist’s death ‘devastating’ as agency moves to UA

The uneasy transition of the Arizona Geological Survey from freestanding state agency to the University of Arizona College of Science must now proceed without the leadership of its director, M. Lee Allison.

Interim Geologic Map of the Ogden 30′ x 60′ Quadrangle, Box Elder, Cache, Davis, Morgan, Rich, and Summit Counties, Utah, and Uinta County, Wyoming

OFR-653DM cd cover

By: James C. Coogan and Jon K. King

The Ogden 30’x60′ quadrangle covers the populous Wasatch Front near Ogden, Utah, and the adjacent Wasatch Range, and extends eastward into Wyoming near Evanston, Wyoming. It covers parts of the Ogden, Weber, and upper and lower Bear River drainages. The Ogden quadrangle is economically important because of the gas and oil fields on the east margin of the map area, the cement plant near Devils Slide, numerous sand and gravel operations, water resources, and recreational interests.



2016 Crawford Award

The prestigious 2016 Crawford Award was presented to UGS geologist Bob Biek in recognition of his work in mapping the Panguitch 30’ x 60’ quadrangle (UGS Map 270DM). Bob’s mapping makes several significant contributions to our understanding of the geology of southwest Utah, including correcting significant aspects of Cretaceous and early Tertiary stratigraphy that have caused geologists problems for decades, and unraveling the enormous and complex Markagunt gravity slide. The Markagunt gravity slide study was initially published with co-authors Dave Hacker and Pete Rowley in Geology. Recognizing the significance of this work, the Geological Society of America recently agreed to fund a Thompson Field Forum on mega-gravity slides to be held in southern Utah in 2017. Additionally, UGS Map 270DM recently received the national Charles G. Mankin Award for geological mapping from the Association of American State Geologists.

The Crawford Award recognizes outstanding achievement, accomplishments, or contributions by a current UGS scientist to the understanding of some aspect of Utah geology or Earth science. The award is named in honor of Arthur L. Crawford, first director of the UGS.
