A new lava flow has broken out at Kilauea Pu’u O’o crater. Kilauea is a volcano in Hawaii that has been continuously erupting for nearly three decades. The lava flow is entirely within the Hawaii Volcanoes National Park and is certainly not dangerous for the population living near the park.
The location was less than half a mile from the Kamoamoa fissure that erupted in March.
Volcanologists say that this was the first time lava has broken out at the volcano since March, aside from some that spilled out at the Puu Oo crater last week. The lava is moving down Kilauea’s south flank. Kilauea is one of the world’s most active volcanoes. It has been constantly erupting since 2 January 1983.
The first video from KITV – ABC Hawaii affiliate gives a very good explanation of what happened in the main crater prior to the current eruption.
At 2:05 p.m. on August 3, 2011, the USGS Hawaiian Volcano Observatory (HVO) monitoring network detected the onset of rapid deflation of the Pu`u `O`o crater floor.
Soon thereafter, at 2:20 p.m., lava broke out at the base of the west flank of the Pu`u `O`o cone.
The deflation of the the Pu`u `O`o crater floor is part of this video.
According to Jim Kauahikaua, HVO’s Scientist-in-Charge, the breakout points are 0.7 km (0.4 mi) east of the eastern end of the Kamoamoa fissure that erupted earlier this year, in March 2011, or about half way between Pu`u `O`o Crater and the eastern end of the Kamoamoa fissure.
The Chain of Craters Road has been closed at Crater Rim Drive and was scheduled to reopen on August 4. The area is of course subject to re-closure at any time.
The second video was uploaded by YouTuber “helenasophiahi” who was able to create her first stop motion.
The entire crater floor of the Pu’u O’o crater collapses in a dramatic display.
She said : The images I utilize are courtesy of the USGS Hawaii Volcano Observatory. Only when I watched the movie for the first time myself, I realized that Auntie Pele had a surprise for me. The entire crater floor of the Pu’u O’o crater collapsed in a dramatic display.
The third ITN video shows the nearly 3 km long Pāhoehoe lava flows searching their way to the Ocean. At night, the flow looks like a spectacular show.
Some footage shows fast flowing lava ( closer to the crater means higher temperatures and fast moving lava in Hawaii)

Volcano information on the Kilauea volcano
Kilauea volcano, which overlaps the east flank of the massive Mauna Loa shield volcano, has been Hawaii’s most active volcano during historical time.
Eruptions of Kilauea are prominent in Polynesian legends; written documentation extending back to only 1820 records frequent summit and flank lava flow eruptions that were interspersed with periods of long-term lava lake activity that lasted until 1924 at Halemaumau crater, within the summit caldera.
The 3 x 5 km caldera was formed in several stages about 1500 years ago and during the 18th century; eruptions have also originated from the lengthy East and SW rift zones, which extend to the sea on both sides of the volcano. About 90% of the surface of the basaltic shield volcano is formed of lava flows less than about 1100 years old; 70% of the volcano’s surface is younger than 600 years.
A long-term eruption from the East rift zone that began in 1983 has produced lava flows covering more than 100 sq km, destroying nearly 200 houses and adding new coastline to the island. (courtesy Smithsonian Institution)
