Wild winds disrupted the Pyeongchang Winter Olympics today as a 17-year-old American snowboarder made history by becoming the first Games gold medallist born this millennium.

Red Gerard, born on June 29, 2000, celebrated a storming win in slopestyle, which also made him the second youngest individual winner in Games history.

“I’m super-psyched!” Gerard said, adding: “I cannot believe it. I’m shaking right now, maybe from the cold or the excitement, I don’t know. But I’m ecstatic. I can’t believe it.”

Slopestyle was one of the events that did not fall victim to high winds today, when the showpiece men’s downhill skiing was aborted until Thursday following a pre-dawn meeting of ski chiefs.

Later, as the gusts continued to swirl around Pyeongchang, the women’s slopestyle qualification was scrapped with the competitors all going straight into Monday’s final.

A day of extremes started with a surprise earthquake alert, after a 4.7-magnitude quake rattled eastern South Korea, with its epicentre about 260 kilometres from the Games.

South Korea isn’t known for deadly earthquakes, but organisers gave assurances that the Olympic venues had been built to stand up to a major tremour.

“All the facilities in the Games area are built so they can withstand strong earthquakes over 7.0 . . . so I assure you there was no issue regarding these facilities,” said Sung Baik-you, spokesman for the Pyeongchang organisers.

The severe chill which has made Pyeongchang one of the coldest Games in history was set to worsen, with temperatures forecast to plunge to -14 degrees Celsius on Monday – with a real feel of -25C.

“People are advised to dress warmly and wear hats and gloves to keep themselves warm,” Sung warned.

On the second day of full competition, Simen Hegstad Krueger led a Norwegian sweep in the men’s skiathlon after recovering from an early fall and breaking a pole.

“It is an indescribable feeling,” Krueger said. “It is an amazing day but it started in the worst way with the fall after the first 100 metres and a broken pole.

“I was completely last in the group so I had to start the race again and switch focus to catch up with the guys. When I did it I was: ‘OK, take one lap, two laps, three laps and just get into it again, and try to do it on the final lap’.”

Dutchman Sven Kramer roared to a third straight Olympic title in the men’s 5,000m speed skating, and Germany’s Arnd Peiffer upstaged French hope Martin Fourcade to win the men’s 10km sprint biathlon.

From near-death to podium

Perrine Laffont claimed France’s first gold medal when she beat defending champion Justine Dufour-Lapointe to win freestyle’s women’s moguls.

And there was drama in the luge when reigning champion and hot favourite Felix Loch fluffed his final run to finish out of the medals and hand victory to Austria’s David Gleirscher.

In the slopestyle, Canada’s Mark McMorris staked an early claim for the most inspirational story of the Games after taking bronze – just 11 months after a near-fatal crash.

In a snowboarding accident last year, McMorris broke 17 bones and suffered a collapsed lung and ruptured spleen, leaving him fighting for his life.

“I don’t want to think too much about the past today, but I appreciate the fact I’m here on my snowboard,” he said, smiling.
