This is how you go completely overboard to protect your home appliances from earth quake!!!
What a question, you are worried about your expensive toy, ha. use a bolt into a stud, that should do it, make it at least a 1/4 inch bolt, and make sure you got the center of stud, that wont shake out of the wall. and make sure your drill bit is slightly smaller then the bolt, and use a torch wrench to twist it in.
Better yet, find the stud you want to mount it on, take out a square of sheet rock around the stud. bolt two more 6” cuts of 2X4 on to the stud, and cover that with plywood. then use four bolts in a bracket, repair the sheet rock, re paint, and then mount the flat screen,
Because in an earth quake it shakes, use sticky foam tape on the wall where the flat screen contacts to stop damage from happening when it shakes, preventing the flat screen from bouncing on a hard surface
Hope this helps you go “Completely overboard with Scrumpulator”
