This is maybe 24-30 inches across and about 100 feet high. We noticed 4 newly dead branches on it and wondered what was up. Then we noticed woodpecker holes about 40 feet up. It is within striking distance of the home. Does it need to be taken down or might it pull through?
Yes, possible lighting strike. Regardless there appears to be swelling of the trunk in your second picture. With the flecking of the bark in this area, I would be concerned.
