The unexpected Mauna Ulu eruption of Kilauea Volcano in Hawaii gave an incredible sight a few decades back. This was the most long lasting eruption which was recorded throughout history. And also this eruption was very easily accessible for the people. Thus, this opportunity has given the photographers to capture some amazing photographs.
The Mauna Ulu eruption in Hawaii was started in 1969. It flowed consistently until 1974. The eruption lasted for 1,774 days. Therefore, according to the U.S. Geological Society, it’s considered as the biggest and most long-lasting eruption which took place in 2,200 years.
This particular volcano was able to spew about 350 million cubic metres (approx. 458 million cubic yards) of lava—the reports of LiveScience shows that this amount is able to melt rock to fill a colossal 140,000 Olympic-size swimming pools.
People were given a chance to experience the spewing lava scenery from an observation platform. USGC posted one of the striking images which were captured in 1969 for their “Throwback Thursday” picture on social media platforms.
A waterfall of lava flowed continuously into the ocean 7.5 miles away for several days, starting from the 10th of October to the 13th October. The picture captured by J.B. Judd shows an incredible sight of a symmetrical “Dome” of lava spewing for about 65 feet into the air amidst the volcanic eruption. The dome was one of 12 separate fountaining events that occurred that year.
The Oregon State University states the lava domes as the results of the “viscous” magma which piles up around the open hole of the volcano.
One of the tweets of the USGS read, “Dome fountain of episode 10, October 10–13, 1969, eruption of Kilauea Volcano. Symmetrical dome fountains such as this are rare.”

“Fountaining” occurs as a result of the expansion of the gas bubbles which are formed within an isolated vent amidst the lava fissure, which causes a spray of lava into the air. It’s true that sixty-five feet reads high. But, some of the fountains usually range from 30 feet to 330 feet. Some fountains are strikingly as high as 1,640 feet – means half a kilometer or more.
The photograph shows as if the lava dome is erupting from water. But, actually, these are not water waves, they are the ripples of lava.
Another long lasting volcanic eruption took place at the end of this voluminous Mauna Ulu eruption. A volcanic vent on Kilauea’s east rift zone, Pu‘u ‘Ō‘ō eruption began in 1983 and it has continued since then. But Pu‘u ‘Ō‘ō eruption was not easily accessible for the public.
“[Pu‘u ‘Ō‘ō] ranks as the longest and most voluminous known outpouring of lava from Kīlauea Volcano’s East Rift Zone in more than 500 years,” USGS sated. “Lava fountains and flows have profoundly altered the landscape and repeatedly challenged residents with lava inundation.”
