This photo of Kraut Creek was taken behind the gymnasium on the Appalachian State University campus, and shows a major nonconformity (a surface of erosion or non-deposition) at the point of the arrow. The underlying rock is the 1200 million year old Cranberry Gneiss, and the overlying sediment (which is a point bar deposit) is, at the oldest, only a few thousand years old. Near Zionville, NC, US 421 crosses a massive debris flow that moved down the side of Rich Mountain into the adj ...

Available: http://pubs.usgs.gov/gip/earthq1/how.html ) An earthquake is the vibration, sometimes violent, of the Earth's surface that follows a release of energy in the Earth's crust. This energy can be generated by a sudden dislocation of segments of the crust, by a volcanic ...

In this site you can find information on geological faults. To find out what these things are and to learn something of their importance, visit the introduction first. You can also choose topics from the column of icons. Most of this material relates to the first year course in structural geology in Leeds (EARS 1053). However, more advanced materials lie behind if you keep exploring. Alternatively you can choose to scroll through the picture gallery.

Geological faults A fault is a discontinuity in a rock mass; locally it can be seen as a plane. It is along this surface that stresses buily up in the earth's crust are relieved by the motion of the two bodies of rock with respect to each other, i.e. an earthquake. The names for the two blocks are derived from old mining nomenclature. The block on top along the fault is known as the hanging wall; the block on the bottom is called the footwall. In a normal fault, the stress is caused by str ...

TOUR OF THE HAYWARD FAULT Introduction to the Hayward Fault The Hayward fault extends from San Jose 120 km or about 74 miles northward along the base of the East Bay Hills to San Pablo Bay. Two types of fault movement occur along faults. One type is the catastrophic rupture of the ground that generates large earthquakes. A large earthquake, estimated to have been about magnitude 7, occurred on the Hayward fault in 1868 and was the "great" earthquake of the Bay Area prior to 1906. Descriptio ...

The Nasca Lines Project (1996- ) Since 1996 I have been collaborating with David Johnson, a teacher, videographer and independent scholar from Poughkeepsie, New York, on a project linking the famous Nasca Lines or geoglyphs with sources of subterranean water. Dave and I met by accident in the Nasca Valley when I was doing preliminary research for my survey of the lower drainage and Johnson was working as a videographer for the Catholic Church documenting the church's activities in Nasca. Whil ...

Plate Boundary Structure Along the San Andreas Fault Author: Furlong, Kevin The San Andreas plate boundary through California represents perhaps the best studied major fault zone in the world. Even with the large amount of geological and geophysical data which have been collected, much is still unknown about the causes, timing, and triggering of major earthquakes along the boundary. In our research at Penn State, we are focusing on improving our picture of the three- dimensional ...

Hop on the bus and let's go for a field trip! Everybody has FUN on the bus. It's early in the morning, and can you believe we're standing on a levee in Watsonville? But look, you can see the San Andreas Fault from here! Let's get a closer look at those offset streams. Can you see the right-lateral fault? "Boy, Cari, isn't that one of that one of the nicest landslides you've ever seen?" Todd sure likes to point. That there is one deep quarry. The joints in that granite have sure ...

THE NEW MADRID FAULT The New Madrid Fault System extends 120 Miles southward from the area of Charleston, Missouri, and Cairo, Illinois, through New Madrid and Caruthersville, following Interstate 55 to Blytheville and on down to Marked Tree, Arkansas. It crosses five state lines and cuts across the Mississippi River in three places and the Ohio River in two places. The Fault is Active, averaging more than 200 measured events per year (1.0 or more on the Richter scale), about 20 per month. Tr ...

Welcome to the UF3 Home Page UF3 is Utah Faults, Fluids, and Fractures - a consortium of researchers at Utah State University and the University of Utah who conduct research on one or more aspects of fault development, fluid flow in fractured or faulted rocks, structural analysis applied to hydrogeologic problems, and mathematical modelling of structures and fluid flow. Our work integrates geology, hydrogeology, mechanics, and probability to solve problems on the flow of fluids in ...
