Quake Follow up Tremors Unlikely. Chicago, Ill. -AP-
It's unlikely there will be any follow up tremors to the earthquake which shook up residents of 22 states, a seismology authority said Sunday. "I expect none whatsoever. We have nothing to worry about," said Father Donald Roll, director of seismological studies at Loyola University. "That was kind of a safety valve. The pressure which had built up has been released."
The quake was centered in southern Illinois about 120 miles east of St. Louis, said the national earthquake center in Washington, D. C. It measured 5.5 on the Richter scale.
[In Wisconsin, the tremors were felt from Milwaukee to La Crosse. There were no injuries, however, and little damage was reported although many people said the shaking frightened them or made them dizzy.]
[Several persons reported that downtown Milwaukee buildings swayed and shook because of the quake. The quake was also noticeable in some private homes when pictures tilted on walls, plates rattled on shelves and small cracks appeared in plaster.]
The quake occurred shortly after 11 a.m. and was felt in Illinois, Arkansas, Minnesota, Ohio, Tennessee, Missouri, Kansas, Georgia, Kentucky, West Virginia, North Carolina, South Carolina, Indiana, Nebraska, Iowa, Alabama, Mississippi, Michigan, South Dakota, Pennsylvania, and Oklahoma in addition to Wisconsin.
(A much more detailed series of articles about this quake were written in the Sunday, November 10, 1968 issue of the Milwaukee Journal starting on page 1.)
