Thousands of Chinese fled for cover in fear of an earthquake on Tuesday, alarmed not only by warnings from seismologists but also by an unusual mass movement of frogs, state media said.For the second time this month, residents observed a huge migration of frogs and toads, the state-run Xinhua news agency said.Residents of Zunyi, a southern city that saw little damage in China's massive earthquake last week, noticed the amphibians' march on Monday, Xinhua said, quoting Vice Mayor Zeng Yongtao.Thousands of residents camped out in fear overnight in downtown Zunyi, the news agency said. "We don't know what else we can do," Zunyi resident Liu Yong was quoted as saying.Their decision to move outdoors coincided with a warning from seismological authorities that there may be another big aftershock in southwestern China's Sichuan province on Monday following last week's massive tremor.The May 12 earthquake, which left more than 71,000 people dead, missing or buried in rubble, also came after reports of unusual movement of toads.Internet blogs showed footage of toads covering the streets of Mianyang in the days before the town in Sichuan province was ravaged by the earthquake.Many people, at least in retrospect, took the toads as an omen of disaster. Others, however, said that the toads had come to welcome the Beijing Olympic flame.Local forestry officials had said the toads' movement was simply because it was mating season, although their explanations were attacked on China's lively Internet discussion boards.
