The unprecedented Mauna Ulu eruption of Kilauea Volcano in Hawaii led to some spectacular imagery a few decades back. Not only was it the longest eruption on record at the time, it was also easily accessible for the public to view. This combination of factors resulted in some amazing photography.
The Mauna Ulu eruption began in 1969 and flowed fairly consistently until 1974, lasting a total of 1,774 days (just shy of five years). It was the longest-lasting and most voluminous eruption in 2,200 years, according to the U.S. Geological Society.
