Citing figures from the United States Geological Survey, he noted that about 40 square miles of the island were buried in fresh lava between 1983 and 2003 alone.
The flames are produced by burning methane gas below the surface.
Thousands of Big Island residents who were living near the lava flows have already evacuated the area to escape the lava flows and noxious sulphur dioxide gases rising from the vents.

He submitted another addendum in mid-May 2017 detailing more than 100 calls or meetings with representatives of more than 20 countries.
Officials said Tuesday efforts to secure the wells from lava by quenching with water or plugging have likely mitigated any risk of an unabated release of hydrogen sulfide.
Joe Kekedi takes pictures as lava enters the ocean, generating plumes of steam near Pahoa, Hawaii. Officials say the power plant is "essentially safe". Lava continues to erupt in two evacuated subdivisions.
Those aircraft are capable of airlifting 43 people at a time, and could be flown if residents become isolated or if an incident happens at Puna Geothermal Venture.
The plant has capacity to produce 38 megawatts of electricity, providing roughly one-quarter of the Big Island's daily energy demand.
Trump seeks to placate North Korea's Kim over uncertain summit
On Wednesday, Bolton brushed aside the North Korean remarks against him and said odds were still in favour of the summit going ahead.
But first of all, the Kilauea eruption began to pick up steam a few days ago, creating a new hazard of "toxic steam" as the red-hot rock interacts with the Pacific Ocean; and secondly, the lava changed direction.
Lava is entering the ocean off Hawaii from a third flow, marking the third week of a volcanic eruption that has opened up almost two dozen vents, destroyed buildings and sent plumes of ash miles into the sky.
Volcanic gas emissions at the summit remain high. Kilauea and its many fissures which are pouring out huge mounts of molten rock are causing massive problems in the immediate vicinity of the volcano, but no effects are occurring away from Hawaii.
At least 44 homes and other structures have been destroyed in the Leilani Estates and Lanipuna Gardens area of the Puna district, and a man was seriously injured on Saturday when a plate-sized chunk of molten shot out of a fissure and struck him on the leg.
Lawmakers are briefed on Trump ‘spy’ claim
The first of Thursday's meetings was originally intended for two Republicans, Nunes and Oversight Chairman Trey Gowdy. Neither Kelly nor Flood was present for the meetings themselves, according to the White House.
Hawaiian Volcano Observatory reported an explosive eruption at the volcano summit at 5:51 pm local time on Monday, and residents have been warned of the resulting ash plume. Scientists say it can trigger explosions if ignited while trapped underground.
