...permafrost is on dry land either. The East Siberian Arctic Shelf, a vast expanse of shallow seafloor off Russia's northeast coast, was once wetland as well. It was submerged as melting glaciers drove sea level up at the end of the last ice age, but it still contains methane-rich permafrost, which Shakhova believes may now be becoming unstable. The numbers are not alarmingly large, she agrees, but what is worrisome is that no leakage was expected here. (See TIME's special report on the environment...
...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, not in the sea."

...Juan Fernández islands in the Pacific Ocean, killing at least eight people and leaving another eight missing, the Chilean emergency office said. Local reports suggested that many fishing villages on the mainland had also been hit by the wave. A warning could have allowed villagers on the coast to flee to higher ground. "The truth, even if it hurts, [is that] a division of the navy made a mistake," Defense Minister Francisco Vidal told reporters. He blamed the navy for not issuing a tsunami warning after the Feb. 27 earthquake rocked the South American country...
Bachelet, however, offered a different account, telling TIME that local firefighters had warned residents to evacuate after a strong quake in a simulation exercise two weeks before last weekend's tremor hit. "When I was in Constitución [a town north of Concepción on the coast], they told me that two weeks earlier, the local firefighters ran an earthquake rehearsal," she said. "They taught the population that if they could not stand up while it was trembling, it meant they had to go up into the hills because there was the possibility of a tsunami...
...force depend largely on the amount of vertical movement an earthquake causes at the sea floor. The 9.0-magnitude quake that caused the devastating South Asia tsunami of 2004 yielded potent vertical displacement of about 16 ft. (5 m); Chile's Saturday temblor, centered just off the Pacific coast about midway between the capital, Santiago, and Concepción, is thought to have involved significant vertical motion as well. Fortunately, no other countries in the Pacific Basin were affected by the Chile tsunami. "But it's hard to understand how the Chileans didn't foresee a major tsunami, at least...
