Let's say there is this a very large industrial-era quadruped machine, somewhere on the order of magnitude of the Bagger 288. Construction is probably similar the Eiffel Tower. For more scale reference points, it's legs have enough throw to at least clear a 4 story building, and it's feet can fit between the buildings of an average-to-wide street.
Let's pretend that this machine is possible in this world (I may ask further questions regarding this) and that it it's existence is somehow justified.
As it takes a step onto the street...
How much damage does it do via impact? The people in the city can put up with routinely filling in a shallow crater the street and re-laying some cobblestone pavers in its wake, maybe some other minor repairs, but not much more.
Would the ground "shake" or bounce like in a cartoon/movie in proximity to the impact? Enough to cause a bit of a nuisance, maybe free some produce from their stands, or cause some people to lose a bit of balance?
Loosely, what is the radius/drop off of these effects?
Out of curiosity, if the ground wouldn't bounce or shake, is that possible at all? How big (roughly) would my walker need to be?
