HALIFAX, NOVA SCOTIA – Today’s “Maritime Image of the Day” shows a 65 foot high, big hot bubble of lava that was taken at the Kilauea Volcano eruption in 1969 in Hawaii.
While lava domes are common, symmetrical ones that form a symmetrical sphere as this one did are very rare. They’re formed by viscous (gooey) magma that piles up around the opening of the volcano, also known as the “vent,” according to research compiled by Oregon State.
This 1969 dome developed during the eruption of Mauna Ulu — a volcanic cone in the eastern rift zone of the active Kīlauea volcano, the youngest on the island.
Lava flowed fairly consistently in this eruption from May 24, 1969, to July 22, 1974.
“[It was] the longest-lasting and most voluminous eruption on Kīlauea’s flank in at least 2200 years,” according to the United States Geological Survey (USGS), noting that the eruption stretched a total of 1,774 days.
