Thanks - interesting perspectiveAs per my pic and comment above:
In that pic, the roof and supporting structure is new, and the new structure may not have been tied properly to the masonry wall at the top, allowing it to flex more in the tremor. Masonry walls are typically weak and need to be tied.
But many possibilities. Masonry facades in earthquakes that fall often do so if not tied back to the structure properly. It may never have been tied (and in particular the top part of the wall may not have been tied if it was built up above the old roofline. The old ties may have corroded. Or the ties at the top where the new work may have been removed and not reinstated, or if so not reinstated adequately.
Or the wall may have had other flaws.
PS. I am an engineer.
Are you just ion the wrong age group? Only affected Hippies didn't it?
Given they all turned up at an agreed time it's hard to believe any of them are actually tradies.

… of course we have no tradies now to do work..too busy with other ‘diversions’
