Thank you for the comment. I am an Alaskan JUNKIE. Our son has lived in Fairbanks for the last 25 years and I try to read all I can about their earthquakes and North Slope Oil. I'm sure you could Google up TAP pipeline and the last major quake and find several stories. Thatis how I got my data about the amount of movement of the earth. There are also several pictures showing the rupture. For the record, the pipeline came within 2 or 3 feet of falling off their supports.
