With its eruption in 40 years, the US authorities on Monday said that the volcano in Hawaii is spewing lava and hot ash, with officials on alert. 

The US Geological Service (USGS) stated that the Mauna Loa has been showing signs of eruption for a few years. 

The volcanic eruption was visible from Kona, a town on Hawaii's main island some 45 miles  (72 kilometres).

For now, the US Geological Service (USGS) said that the lava currently is within the summit and does not pose a threat to citizens living downslope. 

The Hawaiian authorities said that no evacuation orders have been given, summit area and roads have been closed, though two shelters have been opened as a precaution.

Vulcanologist Robin George Andrews said that the eruption was originally contained until now.

Andres taking it to Twitter said, "Oof. Lava is now erupting from fresh vents on the slopes along Mauna Loa's Northeast Rift Zone, or NERZ. That brings a new hazardous dimension to the eruption."

He stated, "The fact that it is a hazardous mountain that hasn't erupted since 1984 the longest eruptive pause in its recorded history -- is why we should all keep an eye on it."
