See a hieroglyph for the personal name Tetzauh in the Visual Lexicon of Aztec Hieroglyphs, ed. Stephanie Wood (Eugene, Ore.: Wired Humanities Projects, 2020–present. https://aztecglyphs.wired-humanities.org/content/tetzauh-mh592r

Frances Krug captures five examples of references in the annals of the Tlaxcala-Puebla Valley to a tornado (mixpantli) that raced across the sky in 1525, 1526, and/or 1544. In one record, tetzauh seems to be used in a parallel construction. See also mixpantli and tetzahuitl. (SW)
