Florida has this solved.
Wood rots and breaks. Burial has flood issues. The solution is to install better poles.
Most commonly, the poles are concrete with a square cross-section. Some are round concrete, spun while hardening to allow a hollow interior. Some are galvanized steel, with perhaps a decagonal cross section.
One near my house is about 2 feet thick, with a label that says 50,000 pounds.
These are not fragile. :-)
