SHOCKS RECORDED AT THE UNIVERSITY Salt Lake, April 0. Ages and ages ago, perhaps when dinosaurs were only pollwogs In size, a slice of the west side of the W.asatch range began be-gan to slip. Intermittently, through the succeeding ages, this west side of the Wasatch fault plane, as scientists scien-tists know It, slipped down and the east side slipped up. These slips have a real name of their own, too. Tectonic displacement is the formal and formidable appellation. All of which may seem foreign to any place but a geological classroom. But it isn't. There was one of the slips yesterday. The uninitiated called it an earthquake. It was, generally gen-erally speaking, but scientifically speaking it was a tectonic displacement. displace-ment. But it was only the dying ages. It was, according to Professor Fred Pack of the University of Utah, one of the last that will be recorded in all probability. The seismograph at the University recorded a slight disturbance, beginning begin-ning at 0:06 3-5 o'clock yesterday morning and continuing for almost exactly one minute. A few perhaps felt it. at least some said they did. In Ogden the shock was felt for about two seconds, according to advices from there. "The earthquake was undoubtedly purely local,"' said Professor Pack last night. "At?cs ago a great crustal block on the western slope of the Wasatch cracked away. It extended from the-site the-site of Nephi to the site of Collin-ston, Collin-ston, a distance of about 120 miles. Intermittently thereafter the block slipped down. Now its movement is practically all past. The shock yesterday yes-terday was probably one of the last movements of that block. Earthquakes Earth-quakes are caused by volcanoes and tectonic displacements, or the slipping slip-ping of crustal blocks, such as the one from the Wasatch. We have no volcanic disturbances to cause earthquakes, earth-quakes, and we will have but little more of this tectonic displacement."
