Yesterday morning, the American island of Hawaii witnessed an eruption of the largest active volcano in the world, the first in nearly 40 years, and it spewed ash without posing any threat to the residents of the surrounding areas.

The Mauna Loa volcano eruption began on Sunday night, according to a warning issued by the American Geophysical Institute.

The institute indicated that the matter does not constitute "at the present time any threat to inhabited areas," noting that there is no indication of the eruption's progress towards the rift area, allowing magma to advance more easily underground.

The authorities did not issue any evacuation orders, but some roads were closed as a precaution.

Hawaii's Mauna Loa, the world's largest active volcano, has started to erupt for the first time in nearly four decades, prompting volcanic ash and debris to fall nearby, authorities said Monday.

And the American Geophysical Institute warned, in its first warning issued on Sunday, that the early stages of the "Mauna Loa" eruption could develop rapidly, and that the locations and progress of the lava flow "could change rapidly."

And the US meteorologist warned of the accumulation of volcanic ash, as it would cause respiratory difficulties for residents or disturbances in the operation of engines and electronic systems.

For his part, volcanologist Robin George Andrews stressed - in a tweet on Twitter - that "we all have to watch what is happening, given that (the volcano) is a dangerous mountain that has not been erupted since 1984, which is the longest period of dormancy in its history."

BREAKING: The Hawaiian volcano Mauna Loa has begun erupting, with lava currently confined to the summit.

It's the first eruption at the volcano since 1984.

This situation could evolve in a number of ways.

The volcano has previously erupted 33 times since 1843, the last of which was in 1984 and lasted 22 days.
