Just kidding, the Galapagos tortoises are fine:A volcano on the largest of the Galapagos Islands erupted for the third straight day Tuesday, but experts said it didn't threaten villagers on the island or the super-sized tortoises that gave the remote archipelago its name. Oscar Carvajal, chief technician of the Galapagos National Park on Isabela island, said tortoises and land iguanas were not threatened because the lava flows were down the northeast slopes of Sierra Negra volcano where there were no animal populations. "The lava flows have not affected the species because they are on the other side. There are no problems with tortoises or land iguanas. Only a small amount of vegetation has been burned in the interior of the caldron and on the flanks," Carvajal said. The 4,920-foot high Sierra Negra volcano began erupting late Saturday, sending three rivers of spectacular lava flow down its northeastern slopes.in 1998.
