This is the presentation that was originally scheduled as the USGS Public Lecture on March 27 but had to be canceled due to "Code Orange" alert status. Click here see the 'flyer' for that lecture. (160 KB PDF file)

Summary

* This powerful magnitude 7.9 quake ruptured the fault for 184 miles, creating offset as great as 29 feet and causing thousands of landslides

* The quake's shaking was felt in Anchorage and produced effects as far away as Louisiana

* Although the ground shifted 14 feet beneath the Trans-Alaska Oil Pipeline, the pipe did not break, a tribute to careful geologic studies and creative engineering

* The San Andreas Fault is similar to the Denali Fault and produces comparable quakes, but unlike the Denali, runs through densely populated urban areas

* Will intensified monitoring of the Denali Fault enable us to forecast where and when the next major quake will strike on that system?
