Keith Perkins  got the phone alert and later heard the sirens going off in  his  southeast Alaska hometown of Sitka.
 He  said people on Facebook were chattering back and forth about whether this was real or not and what they should do.
Given the magnitude of the earthquake   Perkins  said  he  thought it best to head to the high school  a tsunami evacuation point  even though in the past  he  felt  his  home was at a "high-enough spot."
"I figured I'd probably just better play it safe "  he  said.
In Seward  at the southern end of Alaska's Kenai Peninsula  residents retreated to higher ground or left on the only road out of the city  fire chief Athey said. He described  it  as a controlled evacuation and compared  it  to folks driving home from a holiday fireworks show.

Germany's Audi has abandoned plans to sell its Italian motorcycle brand Ducati  its chief executive Rupert Stadler said  in a sign of confidence that the carmaker expects to be able to carry the costs of its transformation.
Steps to reduce costs by 10 billion euros ($11.8 billion)  cut red tape and deepen ties with fellow Volkswagen-owned brand Porsche are "gradually increasing our financial and organizational leeway for the strategic realignment " chief executive  Rupert Stadler  told reporters.
There is  therefore  no economic need to sell Ducati   Stadler  said. Volkswagen asked banks to evaluate options for Ducati and transmissions maker Renk earlier this year as seeks to become more nimble in its shift towards electric and self-driving cars following its diesel emissions cheating scandal.
"I can assure you that Ducati belongs to the Audi family " said  Stadler . "Ducati is the perfect implementation of our premium philosophy in the world of motorbikes."
While pushing the costly shift to zero-emissions and autonomous technologies  holding on to the profitable Ducati division and the lucrative Lamborghini brand has become more important   Stadler  said.
"Looking after a premium bouquet is as difficult as the work of a gardener "  Stadler  said. "Therefore I am pleased with every new flower  with every promising new branch " he added  predicting Lamborghini's sales would double on the back of its new sport-utility vehicle.
Separately   Stadler  said Audi will spend nearly half a billion euros over the next eight years on training staff for the digital age  with steps to develop as well as hire experts such as automotive app-designers and car robotics specialists.

DAYTONA BEACH  Fla. - The Daytona 500 is over  and  Dale Earnhardt Jr.  is off to the Winter Olympics in Pyeongchang  South Korea.
After retiring from full-time racing at the end of the 2017 NASCAR Cup Series season in November   Earnhardt  has been transitioning to broadcasting with NBC.  He  made  his  debut during the Super Bowl pre-game coverage  and - because NBC doesn't take over broadcasting NASCAR from FOX until July - the network is having him cover the Olympics.  He  left for South Korea on Monday.
"I was really nervous when they presented the opportunity to me  especially with geographically where it is and everything going on in the world  " Earnhardt  told For The Win ahead of the Daytona 500 weekend.
I gotta head to the airport at 4:45am. I had the bright idea that Iâd just stay up. Terrible plan. Damn Im sleepy. â  Ralph Dale Earnhardt Jr. (@DaleJr) February 19  2018
  He  added that similar to what  he  did with  his  Super Bowl coverage   his  angle will be the fish out of water.
At Daytona International Speedway on Saturday  Junior talked about how  he  wasn't sure what  he 'd be doing in South Korea because NBC had not yet told  him . And then when  he  addressed the media Sunday before the Daytona 500   he  joked about the right person hearing that because  he  was emailed a schedule that morning.
 Earnhardt  has interacted with bobsledders on social media  and they talked about giving the retired NASCAR driver an 85-mile-an-hour tour of Lake Placid. So whether it's bobsledding or skiing or another sport  someone asked Junior what he'd like to do at the Games.
"I don't want to do anything  " Earnhardt  said Saturday laughing. "I've been talking to the four-man (bobsledders) about coming up there  and that'll be way easier to do in the States than over in South Korea."
While he didn't provide any details about what he now thinks his Olympic schedule looks like  he told For The Win that he's most excited about the four-man bobsled event - which will take place after  Earnhardt  arrives - and the closing ceremony.
"I'm a little nervous  but I know (NBC) won't set me up to fail  " Earnhardt  said Saturday. "They want to have good TV  and they're not going to put me in a position where I won't be able to somehow help deliver that."
