What is a high angle fault?

It is generally accepted as a fault which dips greater than 45 degrees.  It can be either a reverse or a normal fault.

Go to www.usgs.gov.  It's a great site that gives you all sorts of information about earthquaktes, faultlines, etc. I'm not sure if you can view all of North America, but as there are so many faultlines, it may be best to view it in smaller areas.  Good luck and enjoy exploring!

In Geology Fractures in bedrock are structure of a specific region of the earth's crust. A crack or fault in a rock.The solid rock that underlies loose material, such as soil, sand, clay, or gravel. The very basis; the foundation. The lowest point.In Geology a fracture in the continuity of a rock formation caused by a shifting or dislodging of the earth's crust, in which adjacent surfaces are differentially displaced parallel to the plane of fracture. Also called shift.  There are many fault lines across the United States

Normal fault: hanging wall moves down relative to the footwall.\n\nReverse fault: hanging wall moves up relative to the footwall.\n\nSorry don't have time to search for fault diagrams...\n\nwriting lesson plans right now\n\nyou really should do your own homework. :P

It's usually used as a verb meaning to hit or throw something in a high arc

I assume you mean earthquake ;)\n\nTo answer your question, no. Historically, the fault line under Los Angeles and San Francisco is the worst. It is part of the Ring of Fire.\n\nThese articles will explain more:\nhttp://www.crystalinks.com/rof.html\nhttp://en.wikipedia.org/wiki/Pacific_Ring_of_Fire

No amount of engineering can as yet stop a fault from moving. A house, skyscraper, dam, nuclear power plant built on a fault can be destroyed in an instant.\nJoints can not be grouted closed or cemented over, especially if you are building a levee or a dam. Mainly because it is so difficult to map the full extent of the joints.\nFolds can cause variation in the depth and hardness of solid rock.\nUnconformity's are simply that. Unconformity's, a beak in the uniformity of the soil or rock thus affecting the safe placement of support structures and thus the future stability of the building.

Patterns of seismic activity along a fault line.\n\nScientists set up seismographs to measure this activity. Movement along faultlines is not uncommon. But we do not usually feel it b/c it is not strong enough. They, however, can detect these slight movements w/ their sensitive equipment.\n\nThere are some other signs as well. An increase in geologic activity near a faultline can give clues. Uplifting of land is one. Increases in geothermal activity may be another.

The tectonic plates were already broken before oil was drilled, it has always been that way since the earth cooled. Oil drilling is not the reason earthquakes exist.

The entire San Andreas fault system is more than 800 miles long and extends to depths of at least 10 miles within the Earth.

Indonesia is on the boundary of the Asian Plate and the Indian-Austrailian Plate. This boundary is a transform fault (or a strike-slip fault). It is roughly the same type of fault as the San Andreas Fault in Califormia. Java just happened to be where the focal point of the earthquake occurred. It was an unlucky event for them.

Los Angeles and San Francisco would be the big ones but there are a lot of smaller ones in the same danger area. Basically anything that is on or near the San Andreas Fault. Check the map at the link--- actually explore the rest of the site, too--- good info there!
