Volcano that cooled the world in 540 AD traced to El Salvador

The sixth century was a rough time to be on earth: low temperatures triggered crop failure, famine, and widespread death. The culprit, say scientists, were back-to-back volcanic eruptions, one in 536 C.E. and another around 540 C.E. The first likely happened in Iceland or North America. But the location of the second was a mystery.
Izalco Volcano is in western El Salvador on the southern slope of Santa Ana. It is the most active volcano in Central America, having erupted more than 50 times since 1770. Its black symmetrical cone reaches a height of 6,004 feet (1,830 metres). During the 19th century, sailors set their course by the continuous glow from Izalco’s summit, nicknaming it the “Lighthouse of the Pacific.” Multiple measurements on the remains of trees yielded precise dates. The trees all died between 500 and 545 C.E.
