There was no damage to skyscrapers in Manhattan, but there was also no damage to any buildings built on sediments in Brooklyn, Queens, or anywhere else in the city. The bedrock story is a myth. https://buildingtheskyline.org/bedrock-and-midtown-i/

{{Short description|Geological formation in the northeast United States}}
In the United States, the '''Manhattan Prong''' of the [[New England Uplands]] is a smaller belt of ancient rock in southern [[New York (state)|New York]] (including [[Manhattan]], [[the Bronx]], and segments of [[Brooklyn]] and [[Staten Island]]), parts of [[Westchester County, New York|Westchester County]], and upland portions of southwestern [[Connecticut]]. The [[bedrock]] underlying much of Manhattan consists of three rock formations: ''Inwood [[marble]]'', ''Fordham [[gneiss]]'', ''Manhattan [[schist]]'', and ''[[Tuckahoe marble]]'', which are well suited for the foundations of Manhattan's [[skyscrapers]].<ref>{{cite book|title=Rise of the New York Skyscraper, 1865&ndash;1913|page=24|author1=Sarah Bradford Landau|author2= Carl W.

The Manhattan Prong and the [[Reading Prong]] are separated by the [[Newark Basin]] in the south, but the two features merge at the northern terminus of the Newark Basin in the vicinity of [[Peekskill, New York|Peekskill]], [[New York (state)|New York]]. A band of mountains that rise nearly one thousand feet along the northwestern margin of the Newark Basin in New York and New Jersey are called the [[Ramapo Mountains]]. Another belt of ancient metamorphic and [[igneous rock]] crops out along the southern margin of the Newark Basin south and west of [[Trenton, New Jersey|Trenton]], [[New Jersey]]. In this region, the rocks are referred to as part of the [[Trenton Prong]].
