El Chichón volcano, Chiapas, Mexico, erupted explosively on March 29th, 1982, after a repose period of about
550 years. Amongst ten eruptive episodes documented between March 29th and April 4th, only the three
that occurred on March 29th and April 4th produced significant pyroclastic tephra deposits. Here we use analytical
(HAZMAP) and numerical (FALL3D) tephra transport models to reconstruct the deposits and the atmospheric
plume dispersal associated with the three main fallout units of the 1982 eruption. On the basis of
such a reconstruction, we produce hazard maps of tephra fallout associated to a Plinian eruption and discuss
the implications of such a severe eruption scenario.
