Strong wind ripped off part of the metal roof of a university's gymnasium and the thermal insulation layer of a hotel in Beijing. It also blew away a man who was mending his own roof in Shijingshan District. The man landed on the top of a 15 meter-high tree and was rescued by firefighters.
The Central Weather says the 5.6 magnitude quake struck at 8:04 a.m. Tuesday in rural Kaohsiung county, about 28 miles (45 kilometers) southeast of the city of Tainan.

The US National Weather Service (NWS) issued winter weather advisories and winter storm watches for large swathes of the United States including in the Chicago area in the midwest which has been in the grips of an extreme cold snap for nearly a week, with temperatures plunging to below zero (negative 17 degrees Celsius).
Dozens of delays or cancellations were reported Tuesday at Chicago's O'Hare International Airport, the country's second busiest, where hundreds of flights have been cancelled over the past week as the city was slammed by blizzard conditions.
Agony for holiday travelers was also reported at several other airports as the storms in the Northwest and Midwest caused a ripple effect across much of the rest of the country, snarling holiday air traffic at major airports in San Francisco; Houston, Texas; Boston, Massachusetts; New Jersey and New York, officials said.

Bison walk toward the corral during the recent annual roundup at The Nature Conservancy's Tallgrass Prairie Preserve in Pawhuska, Okla.
In the Oklahoma Flint Hills, an autumn moon set on The Nature Conservancy's Tallgrass Prairie Preserve as scientists and cowboys gathered at dawn recently for the annual bison roundup. Instead of horses, wranglers climb aboard trucks. They rumble toward a herd of 2,600 bison standing quietly in a nearby pasture. They drive part of the herd into a tight group, and then stampede them into a holding trap.
The shaggy beasts' heaving breath swirls through the corral into a thick, white fog. Over the next 10 hours, ranch hands use plastic paddles to spank the bison through a maze of alleys and corrals toward their annual physical.

The huge bison huffs with anxiety. Up close, he seems prehistoric - his shaggy brown head hangs low beneath a humped spine, curved horns showing bits of blood. Preserve director Bob Hamilton says he may look like a bison, act like a bison and even smell like one - but he's a cattle hybrid. And if he carries maternal cattle DNA, that could impair his metabolism and his offspring.
WSI Corp. predicted 13 tropical storms in the 2009 season and said seven would develop into hurricanes.
The long-term average during the six-month season is for 10 or 11 tropical storms and six hurricanes.
WSI, based in Andover, Massachusetts, forecast that three of next year's hurricanes would be dangerous storms with a rank of Category 3 or above on the five-step Saffir-Simpson scale of hurricane intensity. Such storms feature sustained winds of at least 111 miles (178 km) per hour.
Biologists from the society's condor recovery project in Big Sur found the lifeless body of a wild California Condor chick lying in thick brush beneath a tall stand of redwoods, only a half mile from its coastal nest site.
The wild male chick, known as No. 475, was recently observed making short flights in the nest area, which is normal behavior for a 9-month-old condor, Burnett said.
Environment Canada senior climatologist David Phillips told CTV Newsnet that "it looks like a very good chance" it will be a white Christmas for all parts of Canada for the first time since 1971.
