Killing trolls is what enables "the ground is shaking" troll raid event, regardless of current boss progress. I've been having those events since before the first boss and still have them sometimes despite the (multiplayer) server being pre-moder at this point. It is also not the only raid event that is separate from boss progress, but I doubt our friend here has started killing off wolves or surtlings to worry about the other ones.

Valheim Wiki says, to enable "the ground is shaking" you have to kill trolls AND The Elder, the surtling event is triggered by killing surtlings AND Bonemass, and the wolf event is triggered by killing Bonemass.
We started a new world with H&H and intended to not kill any bosses, in order to build and explore without any building wrecking events. If one of us needs a particular boss power or material, we make a quick hop to our old world. So far (day 212) we have encountered NO troll raids, NO surtling raids and NO wolf raids, and we have killed more than enough trolls, my stepson has set up two or three "surtling core farms" by digging water under a surtling spawn, and in my attempts to find a 2 star wolf for taming I have killed TONS of wolves in the last few (real life) days... almost two wood chests full of pelt and teeth, and I doubled the stack size with Valheim+ . :D
