High-resolution multibeam echosounder (MBES) and light detection and ranging (LiDAR) data, combined with regional gravity and aeromagnetic anomaly maps of the western Gulf of Maine, reveal numerous lineaments between central New England and the New England seamounts. Most of these lineaments crosscut the NE-SWtrending accreted terranes, suggesting that they may be surface expressions of deep basement-rooted faults that have fractured upward through the overlying accreted terranes or may have formed by the upward push of magmas produced by the New England hotspot. The 1755 Cape Ann earthquake may have occurred on a fault associated with one of these lineaments. The MBES data also reveal a NW-SE-oriented scarp just offshore from Biddeford Pool, Maine (Biddeford Pool scarp), a 60-km-long, 20-km-wide Isles of Shoals lineament zone just offshore from southeastern New Hampshire, a 50-m-long zone of mostly low-lying, WNW-ESE-trending, submerged ridge-like features and scarps east of Boston, Massachusetts, and a ~180-km-long, WNW-ESE-trending Olympus lineament zone that traverses the continental margin south of Georges Bank. Three submarine canyons are sinistrally offset ~1–1.2 km along the Thresher canyon lineament of the Olympus lineament zone.

The loss of the nuclear-powered submarine USS Thresher (SSN 593) acted as a catalyst that accelerated improvements in submarine design, construction and operations. Such improvements resulted in a substantially safer submarine force, thereby making it more operationally reliable. The disaster also dramatically increased the influence of Admiral Hyman G. Rickover in submarine development by giving him the opportunity to promote the system of management he used as head of the U.S. Navy's Nuclear Propulsion Branch. During Congressional hearings on the loss of the Thresher, Rickover convinced members of the Joint Committee on Atomic Energy that his management system, based upon stringent standards of quality control and principles of engineering, was the standard that should be applied to submarine development. The disaster also highlighted the need for greatly improved deep-submergence capabilities within the fleet. Subsequently, deep-ocean search, location and recovery assets were developed, as well as improved deep-sea rescue capabilities.
