Pensacola lies on a small circle that would be nodal with respect to an 

 antinode at the epicenter of the earthquake, in a second-mode (football) 

 free spheroidal oscillation engendered by the earthquake (Nowroozi, 19^5; 

 Smith, 1966) it would be in a uniquely favorable position to record a 

 resonance effect of earth-shaking after the earthquake. It is suggested 

 that a mechanism of this type if within the bounds of credence, might 

 also possibly explain the high density of seismic seiches found by McGarr 

 and Vorhis (1967) in the region of the U. S. Gulf of Mexico coastline.
