COULD A MAJOR EARTHQUAKE HIT SOUTHERN UTAH?

thespectrum.com

A series of springtime lectures starts Friday with a presentation on faults and earthquakes in southwestern Utah, scheduled for noon at the Interagency Information Center, 345 E. Riverside Drive in St. George.

Bill Lund, senior scientist with the Utah Geological Survey, is scheduled to give a presentation on the structure of active earth in southwestern Utah and give insight as to whether the region could experience an earthquake similar to those that recently affected Haiti, Turkey, Chile and Japan.

The April Brown Bag Program series, sponsored by the Dixie/Arizona Strip Interpretive Association, Bureau of Land Management, National Park Service and U.S. Forest Service, will feature lectures each Friday of the month, covering topics such as the geology of Kanab Point, the history of Pioche, and a musical Earth Day celebration.

Lectures are free to attend, but space is limited and those interested are encouraged to obtain tickets in advance from the Interagency Information Center.

For more information, call 435-688-3246.

A just-released map presents southwestern Utah’s geology in unprecedented detail. There is also an innovative 3-D version of the map and a virtual field trip for online viewing. The Utah Geological Survey (UGS) created all versions of the map.

The new geologic map covers 2000 square miles of southwest Utah. It stretches from Zion National Park on the east, through the St. George area, to the Beaver Dam and Bull Valley Mountains on the west, and from the Arizona border north through the Pine Valley Mountains.

St George 30′ x 60′ 3-D Geologic Map and Virtual Field Trip

map-overlayThrough the use of computers and the Internet, and virtual globes such as Google Earth, we now have a way around the inherent limitations of depicting the third dimension on a standard paper geologic map. To help users gain this 3-D advantage, the UGS created an overlay of the new geologic map of the St. George 30′ x 60′ quadrangle in southwest Utah. This 3-D visualization brings the map to life, dramatically showing the relationship between geology and topography. A virtual field trip for the St. George 30′ x 60′ quadrangle, which uses placemarks to highlight selected geologic features, was also created.

Stories a Trench Can Tell—Determining St. George Earthquake Threat

Geologists are digging into the Washington fault about three miles south of the Utah-Arizona border in Arizona. “The fault is three miles east of St. George and runs through the nearby city of Washington,” said Bill Lund, UGS senior geologist. “There is evidence of surface rupturing earthquakes. Our goal is to figure out how often the fault has moved and how large the earthquakes have been. That will help us understand the potential for future earthquake activity.”
