Tag: 上海东泰大厦 Storm Surge Carries Huge Boulders
(Visited 18 times, 1 visits today)FacebookTwitterPinterestSave分享0 A typhoon carried 180-ton rocks 150 feet up a beach—the largest transport recorded in recent times.Watch the video clip in a story on Live Science titled “Super Typhoon Shoved Car-Size Boulders Onto Philippine Beaches.” The scene is pretty scary. Waves destroy a house in seconds in an eyewitness video of the “super typhoon” Haiyan that struck the Philippines in November, 2013. With sustained winds of 195 mph and powerful surges of sea water, the storm carried limestone boulders the size of stretch limos as far as 600 feet inland, and 30 feet uphill. One 30-foot stone estimated weighing 180 tons was carried along the beach 150 feet.“If we didn’t know this occurred from a typhoon, people would have started drawing tsunami maps,” said Andrew Kennedy, a coastal engineer at the University of Notre Dame in Indiana who counted hundreds of boulders during a damage survey soon after Haiyan hit. “There are so many, and they went so far.“How could a common typhoon have the power of a tsunami? A mechanism identified in the 1950s was apparently responsible: infragravity waves.Robert Weiss, a coastal scientist at Virginia Tech in Blacksburg, modeled Haiyan’s waves and storm surge, concluding that rare, tsunami-like waves called infragravity waves were responsible for scattering the huge boulders like they were seashells. This kind of wave forms when ordinary wave sets — the groupings coveted by surfers — merge into one large, long-period wave at steep drop-offs close to shore.This will make it difficult for investigators of prehistoric storm damage to distinguish between the two mechanisms, but it also underscores the tremendous power of moving water.Instant CanyonsAnother example of rapid change from moving water can be seen today in the northwest US. CMI posted an article from 2002 by John Morris, geologist with ICR, about a canyon near Walla Walla, Washington that formed in six days. Initially 10 feet deep and 6 feet wide, it grew to 1,500 feet long, 120 feet deep and 120 feet wide when water was diverted into it back in 1926. Five million cubic feet of material were removed in less than a week.The eruption of Mt. St. Helens also showed the power of fluid motion. A mudflow in 1982 carved a “miniature Grand Canyon” at 1/40th scale through sediments laid down by the initial 1980 eruption (see ICR article). These canyons were observed to form in a matter of hours or days, but it’s also probable that other canyons were formed rapidly before observers were present. It is now thought that Yellowstone’s Grand Canyon, for example, was carved quickly by water that breached ice dams, then eroded through rock weakened by hydrothermal activity (Yellowstone.net).Mars CanyonOn Mars, the major canyon system Valles Marineris is long enough to stretch across the United States. Arizona’s Grand Canyon would fit in one of its tributaries. Just this week, geologists presented evidence that it was carved by glaciers. According to Space.com, researchers using data from the Mars Reconnaissance Orbiter suggested the glacial origin due to high concentrations of jarosite, a rock that only forms on Earth in very acidic water. “Getting an evaporating pool of water halfway up a 3-mile-high cliff is tricky, and the more we looked into the geologic context surrounding the deposit, the less likely a liquid water origin seemed,” one geologist said. Remote sensing also detected evidence of opal in the canyon walls.These stories indicate that changes can happen quickly under the right conditions. “Mr. Slow-and-Gradual” Charles Lyell did not know about infragravity waves. Catastrophism became much more widely accepted a century after him, but his doctrine of millions of years of gradualism continues to infect popular thinking. It also played a major role in Charles Darwin’s views of evolution.Arizona’s Grand Canyon is often still portrayed as a result of slow-and-gradual deposition of sediments. The Tapeats Sandstone, though—the bottom layer of sediments above the Great Unconformity—is littered with house-size boulders. The observational experience with Typhoon Haiyan should indicate the amount of flood surge power required to transport these boulders; it sure wasn’t some spring shower. There are also major folds in the Tapeats, some of them continuing up into other formations above. One fold at Carbon Canyon upturned the sandstone 90 degrees. These folds must have occurred rapidly when the sediments were still soft, because there is no sign of cracking.What will it take to get science out of the rut dug by Charles Lyell? Reinforcement by the media and simplistic interpretive programs have deepened that rut into a canyon that’s hard to get out of. But we should, to get a better overview of the landscape.
Tag: 上海东泰大厦 Federer makes quick work of Monaco at US Open
Roger Federer reached the quarterfinals at a 30th consecutive Grand Slam tournament by making quick work of the 36th-ranked Juan Monaco 6-1, 6-2, 6-0 at the U.S. Open.Federer’s fourth-round match against Monaco didn’t get started until nearly midnight, and thanks to his superb play, it was over shortly before 1:15 a.m. Tuesday.Federer played brilliantly right from the start, taking the first five games – and 20 of the first 25 points – in only 12 minutes. He didn’t miss a beat in the second set, hitting four aces in his opening service game and finishing with 14.Five of Federer’s record 16 major championships have come at Flushing Meadows. In the quarterfinals, Federer will face 11th-seeded Jo-Wilfried Tsonga of France, who eliminated No. 8 Mardy Fish of the United States in five sets Monday.Tsonga upset Federer in the Wimbledon quarterfinals two months ago, coming all the way back after dropping the first two sets.”He’s a tough player. … I look forward to that match,” Federer said. “If I play as good as I did today, sure I have a chance.”Federer compiled a 42-4 edge in winners against Monaco.The start of their match was delayed because the preceding match in Arthur Ashe Stadium – No. 1 Caroline Wozniacki’s 6-7 (6), 7-5, 6-1 victory over No. 15 Svetlana Kuznetsova – lasted 3 hours, 2 minutes.”You have to be ready,” Federer said.Wozniacki, seeking her first Grand Slam title, trailed by a set and 4-1 in the second before coming back to beat the 2004 U.S. Open champion.advertisement”I knew that I had to do something,” said Wozniacki, who faces No. 10 Andrea Petkovic of Germany next. “I had to do something different.”She managed to turn things around thanks to a combination of her own increasingly aggressive play and Kuznetsova’s increased mistakes. Kuznetsova’s 40-20 edge in winners was rendered meaningless by her 78 unforced errors, 52 more than Wozniacki, who reached the U.S. Open quarterfinals for the third year in a row.Tsonga made it this far in New York for the first time, and unlike Fish, he’s already tasted this sort of success. Tsonga made it to the final of the 2008 Australian Open before losing to Novak Djokovic, and got to the Wimbledon semifinals this year – where he again lost to Djokovic.On Monday, Djokovic extended his 2011 record to 61-2 by beating No. 22 Alexandr Dolgopolov of Ukraine 7-6 (14), 6-4, 6-2. Their 16-14 tiebreaker in the first set lasted nearly a half-hour all on its own, with Djokovic saving four set points and finally converting his sixth when Dolgopolov pushed a forehand long to close a 13-stroke exchange.Both men called that tiebreaker the key to the match. One tiny piece of evidence: Dolgopolov double-faulted twice in the opening game of the second set to get broken, and Djokovic was on his way.Asked whether he considered winning that energy- and will-testing tiebreaker to be a physical or mental triumph, Djokovic replied: “Combination of both. But in the end, it was more mental, just to hang in there, try to play right shots at the right time.”Djokovic now meets his Serbian Davis Cup teammate and friend Janko Tipsarevic, who is seeded 20th and made it to the first Grand Slam quarterfinal of his career by beating 2003 French champion and U.S. Open runner-up Juan Carlos Ferrero of Spain 7-5, 5-7, 7-5, 6-2 in a match that lasted more than 3 hours.”Strange feeling,” Djokovic said. “We are professionals. Certainly we both want to win the match when we play against each other. So you kind of forget about friendship. You put that aside.”Most players complained about the wind, which gusted at up to 20 mph (32 kph) and kept changing directions, making even serve tosses difficult.Serena Williams handled those conditions much better than former No. 1 and 2008 French Open champion Ana Ivanovic and beat her 6-3, 6-4 to return to a Grand Slam quarterfinal for the first time in 14 months. She missed about 11 of those with a series of health scares but looks really good so far at the U.S. Open.Against Ivanovic, Williams hit nine aces overall, only lost serve once, and finished off the match with four consecutive unreturned serves that ranged from 99 to 111 mph.”I didn’t even go for winners at any point,” said Williams, who hit only 16. “I just tried to get it over because it was so windy. It was definitely tough.”She’s seeded only 28th because of all of that time away, but now has won her past 16 matches heading into a quarterfinal against No. 17 Anastasia Pavlyuchenkova of Russia. Pavlyuchenkova got past 2010 French Open champion Francesca Schiavone 5-7, 6-3, 6-4 in a match with 21 double-faults and 16 service breaks in 31 games.advertisement”I’m going to say that I don’t want to go out there and enjoy just being on center court playing against Serena,” Pavlyuchenkova said. “I would like to do well, try to fight, and with my effort, I’ll try to beat her.”
