A tree standing at an angle it was not standing at last week. The tell is at the ground, not the top: soil cracked in a curve or a full ring around the base, a ridge or mound of lifted turf on the side away from the lean, a gap opening between trunk and soil on the lean side, roots suddenly visible that used to be buried, and grass torn or wrinkled. Water standing in the crack. Sometimes a groaning or ticking sound in wind.

The tree is not bending — it is coming out of the ground. What holds a tree upright is a plate of roots plus the weight of the soil sitting on them, and saturated soil both weighs less in shear and grips less. Once that plate begins to rotate the failure is progressive: every degree of lean moves the center of mass further out past the edge of the plate, which increases the overturning load, which moves it further still. That is a fundamentally different mechanism from a tree that has leaned toward light for thirty years, and it is the one that puts trees through roofs.
Normally a emergency tree service job: $500 to $3,500 around Indianapolis, depending on size and access. A range, not a quote.
