The stream of lava, about 2 yards wide, triggered pulsating explosions with chunks of molten rock and debris flying high into the air.
Kilauea has been erupting for 30 years.
It erupts from three main areas, the summit and two rift zones, and most of these events are 'relatively gentle'.
'Such explosions can be lethal, as the one in 1790 that killed scores of people in a war party near the summit of Kilauea'.
The United States Geological Survey's Hawaii Volcano Observatory captured footage this week of lava bursting from a cliff into the Pacific Ocean.
The lava firehose was caused when a lava stream converges into a "single large spout", according to the USGS.
"Hot lava mixing with cool seawater produces an explosive interaction that results in fragmented lava-spatter" as well as thin strands of volcanic glass, the society says.
"Some of these incandescent blasts fell on top of the sea cliff behind the ocean entry, forming a small spatter cone".
USGS scientists said the open stream of lava continued to pour from a height of about 66 feet into the ocean from a lava tube exposed in the sea cliff.
Geologists, wearing protective gear, launched a probe to discover more about the lava on January 28.
They also warned that cracks in the mountain could mean that the entire structure is becoming unstable.
'This crack could be a precursor to collapse of an unstable section fo the sea cliff, making the site extremely risky for anyone who ventures too closely to the ocean entry by land or by sea, ' the USGS explains.
Volcanologists flying above the site used special thermal imaging cameras to photograph the crack, which is reaching 220 degrees at it's eastern end. Since then, molten lava has been pouring into the sea like delicious tropical punch from some magical never-ending juice box.
