"Possibly within our lifetime, possibly many generations from now, a large destructive earth­ quake will occur in thfe Eastern United States," Arch Johnson, director of the Tennessee Earth­ quake Information Center, recent­ ly told Congress. "The New Madrid seismic tone is its most likely site, hut we can­ not exclude the possibility of other locations." The New Madrid zone got its name from three massive earth- t.4 and above on the scale and 203 aftershocks that struck in the winter of 1811- 1812, ringing bells as far away as Boston and causing the Mississip­ pi River to flow upstream for a while. Scientists say If a New Madrid earthquake of a magnitude above 8 struck today, there would be widespread death among the 13 f people living in the area from Arkansas to Indiana. Destruction would exceed $50 billion. Otto Nutttl of St. Louis Unlversi- told a House subcommittee i is enough energy In the fault today to produce a magnitude 7.8 earthquake and the longer the wait, "the bigger the earthquake will be." "And while we wait for It, we will see moderately large earth­ quakes of magnitude about 6 to 6.5 occurring every 75 to 100 years," he says. ' Johnson told Congress the large amount of structural damage wrought by a maximum magnitude earthquake in a populated region of the East will be like a nuclear war, without radiation. But, he noted, nuclear war Is not a certainty. "The same statement is not true about a major destructive earth­ quake," he said. "Thus any research, any response and mitigation efforts we engage in now and in the future will not be wasted. "They are going to / pay dividends either for our -- or for future -- generations," he told Congress. Predictions vary on the likelihood of a major quake along the New Madrid, ranging fjrom the near future to about 700 years* because scientists know littt* about intraplate earthquakes. In the West, earthquakes occur crustal m plate boundaries such as along the fault. But to the East, the quakes occurwithin one plate and are too infrequent to associate patterns with active faults that may lie deep within Earth. Scientists are concerned about a major earthquake hitting east of the Rockies -- which they con­ sider the Eastern United States-* for several reasons. More people are exposed because of the high population density; buildings are not constructed with earthquake protections; seismic waves travel farther in the East, and most of the nation's nuclear plants areln. the region mk "The,earthquake threat Is most commonly associated with the West where there is a large to greit earthquake every S6 to 100 years," Samuel Speck of the Federal Emergency Management Agency says. "However, while not occur trouble for professor earthquake occurs in the ibootevery five years." About 280 people met in St. Louis last weekend for a National Earthquake Conference spon­ sored by PEMA By United Press International MADISON, Wis; -- /n economics professor is catching a -'lot of flak from a female colleague because be said doing housework 11 neiily as easy as relaxing. University 6f Wisconsin economist Glen Cain says modern conveniences make housework easier and such activities as shop­ ping, child care, arranging fur­ niture and flowers are "quasi- lebure." Such reasoning does women "an enormous disservice," says Kstheryn Clarenbach, director of Women's Education Resources at theUW-Extension. Clarenbach said housework is easier than It was 80 years ago but SO is virtually every other occupa­ tion. "But try telling the mother of even one or two children, who is also employed 40 hours a week out of the home, that her leisure time is on the rise," she said. Cain's research was prompted by Studies showing that women continued to do the same amount of housework after finding outside jobs. Such studies conflict with the economic theory that leisure time increases as personal income in­ creases. battle continues in Congress By Paula Schwed United Press International WASHINGTON - Democratic congressmen and an administra­ tion official sparred Tuesday about whether to spend more than $900 million a year to provide com­ puters to public schools snd train teachers to use them. Rep. Doug Walgren, D-Pa., chairman of the House science subcommittee holding the hear­ ing, said students frequently know more about computers than their M teachers. Another problem Is that expensive computer equipment Is not available in many school districts. Rep. Timothy Wirth, D-Colo., sponsor of legislation to finance teacher training and buy com­ puters at a cost of $300 million An­ nually for 10 years, said the number Of computer-related jobs is expected to reach 30 million by 1990. If disadvantaged children do not have access to computers, Wlrth said, it "threatens the develop ment of a class of technical il­ literates who will be shut out of participation to our economy," But Gary Bauer, deputy under secretary at the Department of Education, called Wlrth's measure and related bills "ex­ cessively costly" and said they would lead to inappropriate federal involvement iii local schools. Bauer said 17 states already have lgws requiring or recommending some form of com­ puter literacy in their schools: Rep. Albert Gore, D-Tenn., said more is needsd. He proposes set­ ting up a $15 million corporation that would encourage develop­ ment of challenging program! tor computer students. "Our schools are being swept up in a tidal wave of technology without any idea of how to make wise use of it," Gore said. >• He laid computers do hot mere­ ly provide children with technical mastery but also allow them to ex­ periment, create, calculate quick­ ly and proceed at their own pace. Statistics show there were 31,000 computers in elementary and secondary schools four years ago and 395,000 last fall. The number ts expected to double annually for the next five years. There are 40 million children in public schools In the country. A1983Johns Hopkins University survey of all schools showed that the 12,000 wealthiest schools were four tithes as likely to have com­ puters as the 12,000 poorest. Pending in both houses of Con­ gress Is legislation that would en­ courage donation of computers to schools by providing more favorable tax treatment of such charitable deductions. The tax change, which passed the House during the last Con­ gress but died in the Senate, was suggested by the Apple Computer Co. of Cupertino, Calif. Apple had promised to provide one computer free of charge to every elemen­ tary, middle and secondary school in the country. Rep. Thomas Downey, D-N.Y., said the "Apple bill" had scant chance of becoming part of a $49 billion, 3-year tax package, aimed at reducing the deficit, that is cur­ rently in conference. Extinct" genes to provide clues By United Press International BERKELEY, Calif. - Scien­ tists for the first time have recovered genes from an extinct animal that was half zebra, half horse and cloned them, they Tussdaj ofCattfornia also said they now hope to reeeter genes from giant ground sloths and saber-toothed cits. * - . • • Russell Higuchi, a researcher on the project, emphasized that the reiults offer no realistic hope that genetic engineers can recreate living replicas of extinct The strange zebra-horse, once common and known as a quagga, disappeared from Earth 100 years ago after centuries of roaming the grasslands of South Africa, the researchers said. The DNA wps extracted from mummified tissue in a young, stuffed quagga In a West German museum, the scientists said. It Is the first time genetic material, from en extlnet organism has been isolated and grown In quantity through genetic engineering, the researchers said. . The frent half Of the quagga was striped like a zebra, and the back half built and colored like a horse. The lest known quagga, a mare, died Aug. 12,1883, in a zoo in Ant­ werp* Their first goal, the scientists said, is to answer a much-debated question among taxonomists: was the quagga a zebra, or a horse? They said it would probably take about a year to find the answer. Formal announcement of the accomplishment was made at a meeting in St. Louis of the American Society of Biological Chemists. It opens up the possibility that gene fragments from other vanished creatures can be duplicated, said UC biochemist Allan Wilson, in whose Berkeley laboratory the work was done. "Imagine being able to compare the genetic differences of an in­ sect today and its ancestor 26 million years old," said Wilson. When European settlers first ar­ rived in South Africa in the 18th century, quaggas were the most common animals on the plains. But they were hunted to extinction over the years that followed. Stnta ww Interest tops list of farm costs By United Press International URBAN A -- Interest rates con­ tinued to squeeze farth budgets forcing the average central Il­ linois farm family with two children to dig into their savings to meet all their expenses last year, a University of Illinois study shows. Interest was the highest single expense Item, exceeding fer­ tilizer, the next highest, by $10,000, according to k recently completed study that sampled 257 individual farm and family business records. Ninety-four per­ cent of the families in the sample were located In 12 central Illinois counties. In 1983, the average farmer paid more than $22,000 in interest --15 percent of the total cash farm receipts. "It doesn't take much to get from 15 percent to 25 percent," said Del Wilken, extension farm management specialist. "And normally, when interest payments begin to exceed 25 percent of the total cash farm receipts, it often signals financial troubles with cash flows and with the ability to repay debt." Interest, including payment on operating, intermediate and real estate debt, has almost doubled in the last four years, Wilken said. "In 1979, interest paid was 12 percent of the total farm expense -- including all the cash operating expenses. This increased to 21 per­ cent in 1983," he said. Total living expedites for these families increased from $22,300 in 1982 to $23,335 In 1983, Wilken said. When capital items are included -- items that cost more than $200 and last longer than one year -- the total living cost increased from 824,844 to $26,495. According to Wilken, average family savings in 1983 dropped $11,000 from the year before. Cash operating expenses other than in­ terest costs dropped 7 percent.
