Yet unlike Madrid, no large earthquake documented historically or paleoseismologically. Nonetheless, some ongoing seismicity could represent aftershocks an unknown prehistoric event rather as result focused long‐term strain accrual. We compare modern rates with those expected after a earthquake. first adopt extreme scenario which entire 250‐km zone ruptured M 7.9 on eve European settlement region 500 yrs ago, we model its deterministic, probabilistic, stochastic approaches. Each method shows that are significantly higher (to least 97.3% confidence) upper bound aftershock rates. Using reasonable set assumptions, far less 10% be ascribed sequence. thus conclude 90% reflects time‐independent most readily interpreted terms localized release Tennessee. current distinction estimated seismic hazard—based historical instrumental rates—between surroundings warranted, but what localizes still open question.
