Figure F16. A. Figure (modified after Ninkovich et al., 1978) showing the relationship between tephra maximum grain size in a series of major eruptions compared to the tephra in Sample 205-1254A-8R-8, 22-65 cm. B. Median diameter of the particles from the coarsest part of the tephra in Sample 205-1254A-8R-8, 22-65 cm, compared to that found in Sample 205-1253A-4R-3, 85-93 cm, and the limits defined by Walker (1971) from his compilation of tephra data.
