Redwoods are some of the most stable trees in the World. That is partly why they can survive for thousands of years. In my entire career, I have seen very few fall, and only inspected two.

Of those two, one fell because it had co-dominant leaders (double trunks) that fell away from each other, which is more of a structural deficiency than instability. The other, which I suspect was demonically possessed, was a small tree less than thirty feet tall, that literally jumped up out of the ground and onto an Astro van more than ten feet away. A rare ‘updraft’ was blamed.

Almost all of the redwoods here regenerated from the stumps and roots of much older trees that were clear cut harvested a century or so ago. Most of those that grew back with structurally deficient co-dominant leaders are very effectively sheltered from wind by their collective groves…
