“The existence of these earthquake and volcanic rings was known before the pear theory had been defined, but then of course their relation with any peculiar form of the earth was not understood. The ring surrounding the Pacific, or butt end of the pear includes a large part of the shores of the Pacific Ocean, running from Alaska down to the western coast of South America, then across to the East Indies, and back, around the other side, through Japan. The other ring is somewhat smaller in diameter, including the earthquake regions of West Africa and the Atlantic Islands. Now the point of interest is this, as Garrett P. Serviss has significantly said, ‘If the pear hypothesis is accepted, and the two great earthquake rings are found to be definitely connected with the strains to which the planet is subjected in its effort to attain a state of equilibrium, under the forces of its own gravitation and rotation, which tend to compel it into spheroidal shape, then we have a perfectly rational explanation of the existence of certain places where earthquakes are sure to occur more or less frequently, and of other places, like eastern America, where they are very rare and never of maximum violence.’
