The third cholera pandemic (1846–1860) was the third major outbreak of cholera originating in India in the nineteenth century that reached far beyond its borders, which researchers at UCLA believe may have started as early as 1837 and lasted until 1863. In Russia, more than one million people died of cholera. In 1853–54, the epidemic in London claimed over 10,000 lives, and there were 23,000 deaths for all of Great Britain. This pandemic was considered to have the highest fatalities of the 19th-century epidemics.It had high fatalities among populations in Asia, Europe, Africa and North America. In 1854, which was considered the worst year, 23,000 people died in Great Britain. That year, the British physician John Snow, who was working in a poor area of London, identified contaminated water as the means of transmission of the disease. After the 1854 Broad Street cholera outbreak he had mapped the cases of cholera in the Soho area in London, and noted a cluster of cases near a water pump in one neighborhood. To test his theory, he convinced officials to remove the pump handle, and the number of cholera cases in the area immediately declined. His breakthrough helped eventually bring the epidemic under control. Snow was a founding member of the Epidemiological Society of London, formed in response to a cholera outbreak in 1849, and he is considered one of the fathers of epidemiology.

El Chichón, also known as Chichonal, is an active volcano in Francisco León, north-western Chiapas, Mexico. El Chichón is part of a geologic zone known as the Chiapanecan Volcanic Arc. El Chichón is a complex of domes with a tuff ring, made of ejected volcanic material, located between the Trans-Mexican Volcanic Belt and the Central America Volcanic Arc. El Chichón erupted in 1982; prior to this, activity had not occurred since c.1360, although debates in literature occur around an eruption occurring in c.1850.El Chichón became famous for its 1982 eruption. In little under a week, the presumed dormant volcano produced three plinian eruptions (March 29, April 3, and April 4). The eruptions generated a substantial amount of sulfur dioxide and particulates into the atmosphere. The total volume of the eruption was much smaller than the famous eruption of Pinatubo in 1991; however El Chichón's impacts were equally significant on global climate. El Chichón is often overlooked in comparison to other historic eruptions, yet the 1982 eruptions provide important lessons on preparation for volcanic disasters and the influence volcanoes can have on climate.
