El Chichon volcano became known worldwide after it erupted catastrophically in 1982 and killed an estimated 2,000 people. The eruption was immediately followed by an El Niño event in 1982-83, the largest El Niño of the century up to that time. Short-runout pumice flows were produced during the 900 yr BP eruption, which spilled over the crater, entered the heads of the San Pablo and Platanar ravines, and traveled 3 km downstream prior to stopping. … SAGE Video Bringing teaching, learning and research to life. Summary . Optical phe-nomena such as those following the eruptions of Krakatau and Mount Agung in 1963 have also been reported. L'éruption du volcan El Chichón (Mexique) ... le 28 mars, vers 9 h, que s'est produit le changement de type de séismicité déjà indiqué. El Chichón est un petit cône de tuf trachyandésitique à dôme de lave qui occupe une partie isolée de la région du Chiapas au Sud-Est du Mexique, loin des autres volcans datant de l'Holocène. Surface and vault microbarographs and a KS36000 (SRO-type) seismograph operated by Teledyne Geotech near Dallas, Texas (1,797 km from El Chichón) received 22 minutes of infrasonic signals generated by explosive activity. Description: English: A high-altitude aerial oblique view taken on November 4, 1982 shows the effect of the El Chichón eruption about seven months later. El Chichón erupted in 1982; prior to this, activity had not occurred since ca.1360, although debates in literature occur around an eruption occurring in ca.1850. Pour les volcans avec de longues périodes de repos entre les éruptions, il n’est pas surprenant de constater à quel point… Although the volume of the eruption was small (< 1 cubic km of alkalic trachyandesite tephra, similar in volume to Mount St. Helens), El Chichon was also notable because it released an unusually large volume of aerosols (7 Mt of SO2 compared to 1.0 for Mount St. Helens). This caldera formed during the very explosive El Chichon eruptions of 1982 and is a few hundred meters deep and about a kilometer wide. Daté entre 1257 et 1258, ce phénomène éruptif d’une rare violence plonge les 13 e et 14 e siècles dans une période de refroidissement climatique aujourd’hui appelée « Petit Âge glaciaire ».

El Chichón volcano in southern Mexico forms a broad symmetrical cone with a diameter of 10 km at itsbase and is capped by a 600 m wide crater containing a 80 m high andesitic lava dome. El Chichón, Mexico: Home; History ; Location ; Facts ; El Chichon is located in Chiaphas Southern Mexico located at 17.36 degrees N latitude and 93.228 degrees W longitude. The reduction in stratospheric ozone observed at northern mid‐latitudes in late 1982 through 1983 following the volcanic eruption of El Chichón is investigated in terms of ozone loss through heterogeneous chemistry on the aerosol which formed in the stratosphere.

This is a view of the floor of the El Chichon caldera. This week–long eruptive outburst (VEI 5) produced world–wide volcanic gas clouds, extensive ash fall, and surges and pyroclastic flows. A cumulative mass of almost 8 million tons of sulfur dioxide was injected into the stratosphere. Roback and others (1995) used three different models to see if the eruption volcanic eruptions might trigger or enhance the El Niño. This type of atmospheric disturbance is generally associated with high level strat ospheric turbidity [4].
