Yeah guy, just keep walking. This is fine.

Ha I miss read the title. Thought is said Cable. Was a surprise to see the Gable fall like that.

Then there is the remaining roof with no debris or ragged edges hanging there it broke away?

Yep and the guy walking, barely slows down as the thing falls...

Looks to me like a staged video.

Well, how in Christchurch does something like that happen?

Well, how in Christchurch does something like that happen?

Take a real close look at the height and width of the brick faced gable appears to be wider and taller than the roof is. Note the tree on the right side is being bent by a near gale force wind. if the wind is a steady 60mph at ground level possibly gusting to 80, there could be gusts double that at roof top height
A 50 mph wind will apply 5 to 7 pounds of force per square foot, but this increases exponentially as winds get stronger. At 100 mph, that figure jumps from 20 to 28 pounds of pressure per square foot, and at 130 mph, 34 to 47 pounds per square foot of pressure are applied. Adjusting for barometric pressures and mean elevations above sea levels the buffeting of the gusts on the protruding brickwork and the spillage over the entire area of the roof face, exerts tremendous forces given the blind corner at the transition roof to facade.
Brickwork is seldom shares any structural properties with a building attached simply with lathing and the flashing. This could have contributed to it being torn from the building.
