Over the past eight months, there have been two incidents where portions of the downtown icon's facade crashed to the sidewalk. After a section of the decorative cornice fell in April, crews fenced off the sidewalk.
Inspections Commissioner James W. Comerford said officials checked out the Statler this afternoon strictly as a precautionary measure.

3:12 p.m.: The tremors elicited different responses from people.
Michelle Mahaney, a Snyder resident who lived in southern California during the 1994 Northridge earthquake, said she knew right away to stay put or to seek a reinforced doorway or strong table.
"After feeling that and experiencing how scary that was, then to feel this here, it was like, 'OK, I've been through worse,'" Mahaney said. "'I know I'll be OK.'"
Mahaney, a software engineer who was on the seventh floor of Lafayette Court when she felt the tremors, described them as "really slow" and "consistent."
Mahaney's co-worker, Marge Polino, took a different approach.
"I was on a conference call, and I was like, 'OK, I think it's an earthquake. I'm out of here,'" Polino recalled. "I left the building."
A block away, Brian McCarthy didn't feel a thing as he worked an outdoor hotdog cart in Lafayette Square.
"I didn't even notice," McCarthy said. --Denise Jewell Gee
3:06 p.m.: The Army Corps of Engineers has begun checking all of its facilities in the wake of the tremor, said Bruce I. Sanders, public affairs officer in the agency's Buffalo District.
Those checks include the Black Rock Channel, the Mount Morris Dam in Livingston County and the agency's Niagara Street headquarters, where workers felt the quake, said Sanders.
The agency also inspected the 10-acre storage cell of radiological waste in Lewiston at the Niagara Falls Storage Site.
"Within one minute of the quake, our on-site personnel at [Niagara Falls Storage Site] were inspecting the [Interim Waste Containment Structure] and found no problems," Sanders said in an e-mail.
The containment cell was designed by the Department of Energy to withstand earthquakes of up to 6.5 magnitude, he said.
A public meeting on the environmental investigation at the storage site was already scheduled for 6 p.m. today at the Lewiston Senior Center. Corps representatives plan to bring information about the design of the cell in relation to its earthquake resistance. --Aaron Besecker
2:48 p.m.: It is not unknown for this region of Canada to experience earthquakes of this magnitude, but it is unusual, said Don Blakeman, a geophysicist with the U.S. Geological Survey's National Earthquake Information Center in Colorado.
"The vast majority of quakes there are smaller, in the 2 or 3 magnitude range," Blakeman said.
Reports are still coming in from various points in Canada and the United States, but tremors were felt as far away as Michigan, he said.
It would take a quake with a magnitude of 6.0 or greater to cause serious injuries or fatalities in this country, Blakeman said. This earthquake was a 5.5.
"We wouldn't expect very heavy damage. We wouldn't expect injuries. If there are some, they would be minor," he said. --Stephen T. Watson
2:45 p.m.: Gina Browning, director of public relations at the SPCA serving Erie County, says that Scooter, an injured conure -- a medium-sized parrot -- who has been convalescing in her office at the SPCA's Tonawanda location, trembled and screamed all day before the quake.
"It was very unusual behavior for Scooter," says Browning, who has had Scooter in her office for three weeks. "We actually asked each other, 'What's got Scooter so riled up today?' He's been out of sorts all day, shaking and screaming."
Special Events Coordinator Bethany Kloc noticed at 1:43 p.m. that the water was sloshing in a glass on her desk in her nearby office, Browning says.
While the humans stood up to discuss the quake, two dogs in the office area suddenly had a scuffle, Browning says. Staffers separated them without injury. "I never put two and two together with the earthquake and the animals' behavior until later."
Browning said she herself did not feel the earthquake. "I don't even feel when I have a flat tire," she said. --Anne Neville
2:44 p.m.: The quake also was felt parts in Lockport, including the upper floors of the Niagara County Courthouse, where Deputy Commission of Jurors Rebecca Edmister was among those to report plants moving in her third-floor office.
"We thought they were moving furniture downstairs," Edmister said. --Nancy A. Fischer
2:40 p.m.: Matt Davison, a spokesman for the Public Bridge Authority, said traffic was unaffected on the span linking Buffalo and Fort Erie, Ont.
"We do have engineers out doing safety checks, which we do in any instance like this," he said. "It's business as usual."
No problems were reported in any of the Niagara Frontier Transportation Authority's operations -- including the Buffalo Niagara International Airport and Metro Rail -- according to spokesman C. Douglas Hartmayer. --Robert J. McCarthy
2:38 p.m.: Jennifer Sepulvedo was on the ninth floor of City Hall when the earthquake hit.
"I felt the things on my wall chattering and you could see everything shaking and swaying," said Sepulvedo, a community planner for the city. "The building kind of swayed a bit."
Sepulvedo said some workers in the building left because of a concern over aftershocks. "To feel City Hall shaking was just mind-boggling," she said.
At The 2nd Cup coffee shop on Broadway, workers mistook the earthquake for the usual cafe bustle. "I thought we dropped something in the kitchen," said owner Kat Tyler.
The incident has sparked a brief sense of camaraderie in downtown Buffalo as strangers swap stories and call friends to see if they felt anything. "My girlfriend just called me," Tyler said. "She's in the HSBC tower, and she's freaking, because they felt it good."
Patti Zelasko, a legal secretary in a law office on the 14th floor of the Rand Building, said her co-worker a few feet away felt the shaking, but she didn't. "She said, 'Why's the floor moving?'" Zelasko recalled during an afternoon break outside. "I said, 'I don't know.'" --Denise Jewell Gee
2:33 p.m.: "You could feel it on the groud," Shannon Holfoth, 22, of Lewiston, said. "I was sitting on the couch, and I could feel it ... on the couch. It was constant. It lasted 30 seconds."
"It wasn't violent," Holfoth added, "but you could see [an aluminum tree on our wall] moving back and forth, up and down. I never thought it was an earthquake, I thought it was [my brothers]. But it was too strong. You could feel the ground moving."
Here is what Joe Cerrie, a Fredonia village trustee, observed: "The entire building was shaking -- entire building. 183 Main St. Maybe a minute." --Charlie Specht
2:30 p.m.: "I was in the dentist chair in North Buffalo and I felt it. I thought the doctor was moving the chair," said Anne Duggan, spokeswoman for Ciminelli Development Co. "I looked up, and the light, the arm, was moving. It was pretty strange." --Jonathan Epstein

2:15 p.m.: Kevin J. Brick Jr. was working on his laptop in the living room of his home on Niagara Street in North Tonawanda when the shaking started.

Friends who lived on Payne Avenue had pictures falling off their walls, Brick added. --Aaron Besecker

2:05 p.m.: "Everybody on the floor noticed it," said Annie Deck-Miller, spokeswoman at Roswell Park Cancer Institute. "Everyone was pretty relaxed about it, but interested.
