Lava and volcanic gas emissions at Hawaii's Mauna Loa, the world's largest active volcano, declined today, the US Geological Survey's (USGS) Hawaiian Volcano Observatory said.

As a result, the Observatory downgraded the alert level for the volcano to a watch from the previous level of warning, with lava confined to a small area.

Under a watch alert level, an eruption is under way but poses limited hazards.

Mauna Loa began erupting in late November for the first time since 1984, ending its longest quiet period in recorded history.

The lava flow front in the Humu'ula Saddle region stagnated 3.06km from the Daniel K. Inouye Highway, also known as Saddle Road, and is no longer a threat, the Observatory said.

The behaviour of the volcano suggests the eruption may end soon. However, an inflationary trend of Mauna Loa's summit is accompanying the decreased activity, the Observatory said.

"There is a small possibility that the eruption could continue at very low eruptive rates," it said.
