Necessarily, the seismographs never see daylight, and the station workers must work by red light or in complete darkness when handling undeveloped records. a combined system, the stations can pinpoint the area in which the quake occurred, the direction from which it came, and its magnitude on the Richter scale. Mr. Bellow notes that Utah experiences "ast least 30 earthquakes per month." "More than that actually occur," he said, "but generally only 30 or so can be located on three or more, stations."

R.

City traffic will really disturb the readings." "To compensate, they have to turn their magnification way down."

The Wood- - Anderson readings, are maintained at the University. The readings are also recorded on 35mm film at Dugway, and sent through the University to the Atomic Energy Commission. SIMPLY PUT, a seismometer is a permanent magnet set in a coil, so that movements in the earth's crust cause the magnet to move, creating an electrical current. This current is registered a galvanometer and through transformed into a light signal, which is recorded on photographic records from the Mr. Bishop looks over the The "at the station. photographic records are previous day developed by the station operators and forwarded to the University of Utah for reading by University Seismologist R. Steve Bellon. From the school, the charts will be sent to National Oceanic and Atmospheric Administration (NOAA) offices in Washington, D.C long-perio- d LONG PERIOD seismo- meters have a longer pendulum holding the magnet, and thus pick up smaller vibrations, from great distances. Variance in temperature can affect the magnets and give a false reading so part of the operator's job is the careful checking of any movement in the machines due to a rapid or extreme temperature change. As a preventive measure, the long- - period machines are covered in insulating styrofoam. Equally important to the station's operation is. the calibration of time. All stations must be precise in working with time to insure accurate correlation of data from the network. TO THIS end, each station is hooked into Greenwich Mean Time, and dailv calibrations of this system become an integral part of station operation. The Dugway console regulating the time marks on the daily charts is accurate to 11000 of a sees oud, while the graphs are accurate to 151000 of a second. "Time is the single most important factor," Mr. Bishop said. And at 2358 hours, Creenwich Mean Time, every day, someone stands ready to make the neces- sary calibration to the Dugway unit. In his five years as station operator, Mr. Bishop has learned enough about seisinography to give at least a surface reading to the charts. "I'M NO seismologist," he says, "but it's interesting to see how well I can read what's hap. pening over the world." "The press picks up local quakes and gives them pulicity even when they're small, but a big quake in the ocean somewhere goes unnoticed," he said. hut Unpublicized, maybe unnoticed?

Performing at Halftime A, Marching at Provo There's no business like band business A welcome sight at Dugway High School football games and other events this school year is the appearance of the Dugway Marching Band for the first time in the past four years. As many Dugwayites can testify having seen the band members practicing at 7 o'clock in the morning and again in the evenings the fine results achieved by the band is the result of many hard hours of work. THE BAND, under the direction of Mr. Allan Cook, high school music teacher, started practicing on their own last summer and has increased in size throughout the year. It now numbers 50 members with 35 being seventh through ninth grade students. Many honors have already been achieved by the band as they received a Superior Rating in sound and marching in the Region Nine Band competition hosted by Dugway. The band was also rated very high at the Brigham Young University Band Day commemorating homecom ing at Provo gaining a third place standing out of over 20 bands participating. The bands next appearance will be at Logan tomorrow afternoon during halftime ceremonies of the Utah State homecoming. It will also be a homecoming for Mr. Cook, a native of Ogden and graduate of Utah State University last June. THE . BAND will also present two concerts at Dugway in the coining months, one at Christmas and the other next Spring. Mr. Cook stated, "It is certainly gratifying to work with the hand memliers, they have so much pride in the band and so much pride in themselves. I also want to thank the community for their great assist- ance and certainly the parents of the band memliers."
