I did a quick check, and a "Siberian sea was due to a punch downwards" would have most simply resulted in a counter-bulge upwards off the southern tip of South America, the existing bulge is too far north. Although the compression waves refracting through the mantle/core interface could be invoked as a way for the Siberian sea and the Brazilian bulge to be linked. (Brazilian whacks?)
