Well about a week ago I was jolted awake in the morning by an earthquake. They are a common occurance here. The only thing that happened was that a stack of paintings leaning against the wall fell over. I righted them, thinking it was no big deal.
I retrieved it and was dismayed to see this 4 inch rip in the canvas. What a bummer. I think that I can repair it to some extent by gluing a swath of canvas onto the back with acrylic medium. Then I can fill the torn canvas with gesso, then paint.
The painting will have a noticeable scar, and it will have to be sold at a substantial discount. I am glad that I had the painting professionally photographed before the damage happened. Nevertheless, it is a lot of labor down the drain. Boo hoo.
