As in Xanathar's Guide to Everything except it is a bonus action to cast, the quake activates on cast and as a bonus action on subsequent turns, creatures take 4d4 bludgeoning damage on a failed save or half as much on a successful one, and the following added:

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the radius of the second ability increases by 5 feet, and the damage increases by an additional 2d4 bludgeoning damage for each slot level above 6th.
