Dike break perils 70,000intyphoon-strickenislesMANILA, The Philippines (UPI) — A major dike burst today in the Philippines’ typhoon-devastated central plains, sending floodwaters to rooftop level and endangering at least 70,000 nearby residents.The official Philippine News Agency said authorities sent out an urgent call for motor boats and amphibian trucks to evacuate an estimated 10,000 families — or 70,000 persons — living along the Amedo Dike, 60 miles north of Manila.The death toll caused by floods and high winds spawned by slow-moving Typhoon Olga stood at 53. The number of refugees totaled 139,500, according to official figures, and was expected to increase.The floods first hit the Manila area and then extended into the rice-growing areas of central Luzon.President Ferdinand Marcos went on nationwide radio and television to declare the entire main island of Luzon a disaster zone. More than half the nation’s 42 million population isconcentrated on the island.The presidential proclamation broadened the list of goods covered by price controls to include candles, matches, canned goods, fish and instant coffee. The decree was aimed at combatting profiteering andhoarding.Marcos reported the loss of at least 15,000 acres of ricelands ready for harvesting and said one province, Nueva Ecija, 90 miles northeast of Manila, was almost entirely under water.He said improved weather conditions were forecast the next few days but warned “it is necessary for our people to steel themselves for furthersacrifice.”Olga was reported to be more than 200 miles west-northwest of Manila late Monday, and moving slowly at less thanthree miles per hour, with peak winds of 70 miles per hour, toward the South China Sea.Another typhoon, Pamela, was reported slowly moving about 300 miles northeast of Iwo Jima today.The Japanese meteorological agency reported Pamela’sforce was diminishing. The agency said the typhoon was expected to veer east and there was little danger it would strike Japan’s main islands.Pamela earlier inflicted $300 million in damage on Guam. President Ford declared the American island a major disaster area.
