literally, ''"Burning mountain"'' is an active
volcano
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

Geography
Mount Yake is the most active of all the volcanoes in the Hida Mountains. Its two main peaks are the northern and southern peaks, but visitors can only ascend to the northern peak, as the southern peak is currently a restricted area. A

Eruptions
In 1911, 22 minor eruptions were recorded. In 1915, during the
Taishō period, however, there was a major eruption. The flow of the lava blocked the
Azusa River, which caused the river to form a lake that was named
Lake Taishō.
The Azusa River is again flowing today, but the lake still remains.
In 1962, there was an eruption that killed two people staying at a small hut near the mouth of the volcano.
In 1995, a tunnel was being constructed on the Nagano Prefecture side of the mountain, through
Mount Akandana, which was thought to be part of Mount Yake. At 2:25pm on February 11, the workers encountered

Volcanic gases are gases given off by active (or, at times, by dormant) volcanoes. These include gases trapped in cavities (Vesicular texture, vesicles) in volcanic rocks, dissolved or dissociated gases in magma and lava, or gases emanating from ...
