Show SLIGHT EARTHQUAKE SHOCKS REGISTERED THIS MORNING i- i I L The above Is a photograph of the Be seismogram made at the university Saturday night It will be observed that there there were three three distinct disturbances disturbances the first or upper 0 one ne coming from a distance of abo about t 1000 mii miles s and therefore not 10 local cal in In ln origin The second had Its origin much closer probably within a radius of mlles miles while the third shock represented on th the bottom line was wholly local and was the one felt so prom prominently In Salt Lake I. I I The unusual nature and the the severity of ot the the earthquake disturbances disturbances disturb disturb- ances which w were re felt In Salt Lake during Saturday ev evening were ex explained ox- ox planed th this s morning in an Interview wit with Dr Frederick J.
