ANCHORAGE, Alaska — A powerful 7.8 earthquake has struck the Alaska Peninsula, triggering a tsunami warning that sent residents fleeing to higher ground before it was called off without any damaging waves. According to the U.S. Geological Survey, the 7.8 magnitude quake struck Tuesday at 10:12 p.m. local time. The quake was centered in waters 65 miles (105 kilometers) south-southeast of Perryville, Alaska at a depth of 17 miles (28 km), deeper than an earlier estimate.

An Iowa grandmother won half the 7 million Powerball prize and she didn't even know it at first.Lerynne West, 51, bought her tickets at Casey's General Store in the small town of Redfield, Iowa, while grabbing pizza and coffee with her sister. She said it was a special day because she had bought her first home and was moving in that day.West thought she put the lottery ticket in her purse, but she accidentally left it on the floor of her sister's truck. It lay there for a couple days.When a friend texted the day after the drawing to ask if she had won, West said she hadn't had a chance to check. She rifled through her purse and realized she didn't have the ticket. She quickly called her sister, who found it.West looked at the photo of the ticket her sister sent her and checked the numbers on the lottery's website -- she had won!"I told my sister to get in her truck and get that ticket and get up here right now! And, drive slow," West said in an Iowa Lottery press release.West's ticket and a ticket purchased in New York split the 7 million Powerball jackpot in the October 27 drawing. The holder of the New York ticket has not come forward, according to the Iowa Lottery.West opted to take home 8.1 million in a lump sum, minus what's taken out in taxes. Her other option was a 3.9 million annuity that would be disbursed over 29 years. She is the winner of the largest lottery prize to date in Iowa. 1435

An American Christian missionary is thought to have been killed by tribespeople from one of the world's most isolated communities on a remote island hundreds of miles off the coast of India, according to officials.The 27-year-old American, identified as John Allen Chau, came to India on a tourist visa but came to the Andaman and Nicobar islands in October with the express purpose of proselytizing, Dependra Pathak, Director General of Police of the Andaman and Nicobar islands, told CNN."We refuse to call him a tourist. Yes, he came on a tourist visa but he came with a specific purpose to preach on a prohibited island," Pathak said.Chau did not inform the police of his intentions to travel to the island to attempt to convert its inhabitants.The island, North Sentinel Island, is inhabited by the Sentinelese people, who are protected under Indian law. Just more than a dozen people are officially thought to live on the remote island in the Andaman and Nicobar archipelago. 989

Anyone scared of snakes on the ground may not want to read this story — because the reptiles are also in the sky.The paradise snake, which is native to south and southeast Asia, has been known to scientists for some time. But they never really understood how the species — and others like it — are able to glide through the air.Researchers at Virginia Tech conducted controlled tests with the snakes in an indoor environment. They discovered that the undulating motion the snakes exhibit while gliding stabilizes them, which allows them to fly further. Previously, researchers thought the snakes' movements in the air were the same movement they used when slithering on the ground.Now, researchers say they want to learn how the snakes generate lift and how they can turn in the air.Luckily, while the paradise snake is poisonous, its venom is weak compared to other species. Like almost all snakes, the paradise snake is considered harmless to humans. 960
