collapse, break
垉 centers on structural failure: something collapsing or breaking apart, often applied to earth or built structures.
垉 combines 土 (earth) with 包, which likely contributes the sound ホウ. The exact historical development is uncertain, but the structure suggests a phono-semantic compound related to earth or ground.
The left side is earth 土, and the right side 包 looks like something wrapped up. Imagine the earth wrapping around a structure and squeezing until it collapses and breaks.
For ホウ, picture a building collapsing with a loud 'hoe!' sound as the earth gives way: hoe -> ホウ, and the ground breaks apart.
