Published on: August 7, 2017
Erupción del volcán El Chichón, Chiapas, México, del 28 de marzo al 7 de abril de 1982
Resumen
La erupción del volcán El Chichón en 1982 liberó 0,3 kilómetros cúbicos de material piroclástico andesitico. Las erupciones iniciales produjeron tefra rica en cristales, diferente de las descargas posteriores de material piroclástico lítico.
Área de la Ciencia:
- Volcanología Volcanología.
- La geoquímica es la geoquímica.
- Ciencias de la Tierra Ciencias de la Tierra
Sus antecedentes:
- El volcán El Chichón, inactivo en tiempos históricos, experimentó erupciones significativas a partir del 28 de marzo de 1982.
- La actividad volcánica involucró tres grandes erupciones de tefra durante un período de diez días.
Objetivo del estudio:
- Para analizar las características de la tefra descargada durante la erupción de El Chichón en 1982.
- Para comparar la composición química y material de la tefra de diferentes fases de erupción.
Principales métodos:
- Análisis de muestras de tefra de la secuencia de erupción de 1982.
- Caracterización de la composición del material piroclástico, incluido el contenido de sílice y álcali.
Principales resultados:
- Aproximadamente 0.3 kilómetros cúbicos de material piroclástico andesitico estallaron en erupción.
- La erupción inicial produjo tefra rica en cristales con mayor contenido de sílice y álcali.
- Las erupciones posteriores (segunda y tercera) descargaron materiales piroclásticos líticos, distintos de la fase inicial.
- La tefra inicial era predominantemente juvenil, mientras que las erupciones posteriores contenían tanto fracciones líticas como juveniles.
Conclusiones:
- La erupción de El Chichón de 1982 exhibió fases distintas en la composición de la tefra.
- Las variaciones en la tefra sugieren cambios en la fuente de magma o la dinámica de erupción durante el evento.

Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
Chickenpox
Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
Efflorescence in Masonry
Efflorescence in masonry walls appears as a fluffy crystalline powder, often white, resulting from water-soluble salts within the masonry or mortar. When water penetrates the masonry, it dissolves these salts and brings them to the surface, where they are deposited upon evaporation of water.
While initial efflorescence is common post-construction and can be cleaned with water and a brush, in certain instances, efflorescence can reappear and gradually diminish over time as salts are leached out...

Endoscopic Procedures V: ERCP
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Ecological Disturbance
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a forest...
