TOKYO, Japan - On Saturday, the Meteorological Agency of Japan said that one of the few most active volcanoes in the world and the most active one in Japan erupted.
The ash generated by the eruption from the volcano covered 11,000 meters (7 miles) of the sky.
The Director of the agency's Volcanology Division, Makoto Saito stated, "It is extremely rare for an eruption column to exceed 10,000 meters."
Ichinomiya district of Aso city, located 8 kilometers northeast of the volcano, witnessed an ash fall and the agency warned that Shikoku region will also face probable ash fall too.
Saito commented on the volcano's active phase and said, "There is a possibility that a same scale of eruption will occur again."
In order to alert people nearby, the Meteorological Agency issued its third-highest level of alert that ranged on a five-level. Warning of gas and falling rocks at one of the peaks of the Kumamoto chain was also issued.
The public television of Japan, NHK, ran the footage of orange flames emerging from numerous locations on the mountainous region.
However, there were no houses situated close to the area of the eruption and no injuries or damages have been reported so far, local media reports confirmed.
The time of the volcanic eruption is said to be 1.46 am local time on October 8. According to records, this particular peak has reportedly been inactive since it exploded in January 1980.
Japan Times reported an official stating, "Mount Aso is in an unstable condition and could erupt again on the same scale."
The eruption that took place on Friday was of a minor category.
So far, officials have said that there isn't enough evidence to relate the eruption to the earthquake that hit Kumamoto and Oita in April and killed 49 people.
Japan, that sits along the Pacific "Ring of Fire," is said to witness most of the world's earthquakes and volcanic eruptions. The region accounts for about 20 percent of the world's earthquakes of magnitude 6 or higher also experiences several volcanoes.
On September 27, 2014, Japan came across the most fatal eruption in 90 years which occurred in Mt Ontake. The eruption was an unpredicted one and caused the death of at least 63 people, most of them hikers.
Currently, a dozen volcanic warnings are in place.
