Near where I live there is a stand of Eastern White Pines that are all about 100 feet tall.
Last year one of the trees was struck by lightning and severely damaged, partially collapsing. The top of the tree that was struck fractured off.
I notice that the two trees that were on either side of it now appear to be dead. All their needles from top to bottom are brown.
Is it possible that lightning somehow killed these trees by electrocution without physically destroying or damaging them in any visible way?
I would note that these trees are very closely connected. The part that was struck was actually coupled to one of the trees and grew out of the same root. That half (the half of the tree that was struck) is completely dead and has insect borings in it. The third tree, even though it is not visibly conjoined to the other seems to share roots with it somehow because its base is right next to the base of the other.
Also, I would mention that both trees have a strange wet spot near their bases. The wetness appears to be water and in both cases covers about half of the circumference of the trunk and is about 3-4 feet in height.
