If it followed the annual ring, that was already there. If it was from drying unevenly, those are perpendicular to the rings, or radially from the heart.

As for lightning, yes it can cause something similar, but there will always be a little crease where the scar tissue meets in the middle as it comes in from both sides capturing a little bit of bark.
Depending on the severity, some may heal over within the same year, but some may be 5-6” wide and take several years. In those you can see where the annual ring curves in and terminates against the year before, maybe several times befor it meets the new scar tissue from the other side.
