c. January – A giant volcano erupts. No one is sure where, but it may have been in a tropical location like El Chichón, Mexico or Quilotoa, Ecuador. Observed effects of the eruption include the following anecdotal accounts: dry fog in France; lunar eclipses in England; severe winter in Europe; a "harsh" spring in Northern Iceland; famine in England, Western Germany, France, and Northern Italy; and pestilence in London, parts of France, Austria, Iraq, Syria, and South-East Turkey.
