...quake, which struck the Tibetan plateau at 7:49 a.m., is one of the largest recorded in the immediate area, which is rife with seismic activity. The May 12, 2008, Sichuan earthquake, which killed 87,000, was centered about 375 miles (600 km) to the southeast of the Qinghai temblor. So far at least 11 schools have collapsed in Qinghai, and the number of dead students stands at 66, with dozens more trapped, provincial education secretary Wang Yubo said. Two years ago as many as 6,000 students died in collapsed classrooms in Sichuan. The anger of their parents, some...
...strokes of luck from which science is made. The seismic shift continued to set off aftershocks almost every day, but Grant stayed to count her toads. When a full moon rose three days after the quake, a few toads risked a return. But then their numbers dropped again, remaining low until two days after the last major aftershock - a full 10 days after the first tremor. "It's never been reported to have happened before," says Grant. "Once they're breeding, then they're breeding. That...
...spikes in the amount of radon gas in the water. "Toads are very sensitive to their environment," she says. Now that at least one potential connection has been drawn between toads and earthquakes, she says, scientists could look for similar reactions in other toad populations that live in seismic areas and are being monitored by conservationists. She suggests exploring how toads respond to some of the changes she believes could have triggered their mass exodus. (See where toads place in TIME's top 10 invasive species...
...century later, it turns out that the Portuguese were right. Seismic tests over the past 50 years have shown that countries up the coast of East Africa have natural gas in abundance. Early data compiled by industry consultants also suggest the presence of massive offshore oil deposits. Those finds have spurred oil explorers to start dropping more wells in East Africa, a region they say is an oil and gas bonanza just waiting to be tapped, one of the last great frontiers in the hunt for hydrocarbons. "I and a lot of other people in oil companies working in East...
Further hindering an early warning for residents was a seismic-information system used by Chile's navy that initially provided inaccurate data on the location of the earthquake. Bachelet pledged an evaluation of the system. "There will be a moment in the future when we must evaluate [how our warning system functioned] in detail," she said. "We have a navy [measurement] system that has 19 installations along the coast. The information in the beginning was not exactly from the central point where the epicenter hit. It was thought in the beginning that the epicenter was down in the earth...
