Volcano Pico de Orizaba

Citlaltépetl, 'Gunung Bintang' dalam bahasa Nahuatl, adalah puncak tertinggi Meksiko dan gunung api tertinggi di Amerika Utara. Tenang sejak 1846, gunung ini masih menyimpan gletser terbesar di negara itu yang menyusut dengan cepat, dan letusan baru akan mengancam kota-kota di negara bagian Puebla dan Veracruz di bawahnya.
