********************************** El Chichón Conference March, 2007 ********************************** From: José Luis Macías <macias@xxxxxxxxxxxxxxxxxxxxxxxx> First Circular El Chichón Volcano: Twenty five years later San Cristobal de las Casas, Chiapas, México March 20-25, 2007 On March 28, 1982 a powerful explosion culminated months of uncertainty and apprehension for the inhabitants of the region in the neighborhood of El Chichón, an inconspicuous volcano in the southern Mexican State of Chiapas. The ensuing 7-day eruption resulted in two thousand deaths, disruption of human activities in the area, and a significant impact on the atmosphere. This brief but violent eruption was accompanied by a sulfur-rich trachyandesitic magma that contained anhydrite as a primary mineral. The eruptive column injected aerosols that had a global impact on the atmosphere. The 1982 explosive behavior of El Chichón is also noteworthy for the complex generation of alternating magmatic-hydromagmatic eruptions that destroyed approximately 100 km2 of forest. The main purpose of this international conference is to commemorate the event with the aim of reassessing our knowledge on the eruption and also to review the status of our science, particularly with respect to explosive eruptions, their characteristics, impacts and consequences. The conference is organized by UNAM (Universidad Nacional Autónoma de México) and Universidad de Ciencias y Artes de Chiapas (UNICACH) and is sponsored by IAVCEI. The conference will consist of invited lectures by well-known specialists in different aspects of explosive volcanism and its impacts, and related contributed presentations. In particular we encourage contributions on: 1) Interrelated magmatic and hydromagmatic eruptions 2) Stratigraphy and eruptive mechanisms 3) Sulfur and aerosol emissions 4) Chemistry and petrology of sulfur-rich magmas 5) Volcano seismology 6) Volcano monitoring 7) Social impacts of volcanism 8) Risk assessment List in alphabetic order of External Invited Speakers: 1.
