The wide root base helps in keeping them rooted, the fiberous nature of the trunk is what keeps it from snapping (bend one dowel rod, and it snaps easy. Bend 6 dowel rods bound together from end to end, and they will flex without snapping). The fronds are not as strong as the trunk, they are more likely to snap of in high winds, and then just grow back later.
Palm wood is a nightmare to split, and does not burn well unless you make it look like shredded wheat (which isn't worth the trouble unless it's all you have to work with). To split it, it's best to chop it into short logs, and then split small pieces around the outside working your way into the middle. If you try to split it by hand down the middle, it will string up between the halves, and you will waste a lot of time trying to pull them apart. If you must go that route, a good ole fashioned hand saw, or pruners is a lot easier at clipping the strands in the middle.
I drove around taking photos during hurricane Charley (what can I say, I live dangerously). I saw a lot of palm trees nearly bent to the ground during that adventure. Most all of the trees that I saw break were not a palm variety. Ringed tree's can snap in hurricane force winds. We had a lot of trees to remove after the storm.
If you have the time, and the tools, a large self feeding auger bit down the middle will help rot it out faster.
Another thing you could do is dig it out around the base, and chop the roots with an axe, then drag it out with machinery, or a railroad tie tripod, and a winch after you have cut the large roots around the base to a depth of about 18".
