Over the volcano Sakuradzima appeared strange lights foreshadowing a new earthquake?

The Sakurajima volcano is located on the island of Kyushu in the Japanese prefecture of Kagoshima and is followed constantly by video cameras installed by scientists to gather information about the state of this dangerous giant.

June 20, 2018 surveillance cameras detected something unusual. Everything happened at night and suddenly the brightest source of blue light appeared at the base of the cone of the volcano, which grew brighter and brighter until it lit up the whole sky with its light, and then suddenly went out.

Interestingly, the same unusual anomalous phenomenon was noticed here in 2011 shortly before the devastating earthquake that shook Japan. The magnitude of the tremors was 9 on the Richter scale, and the resulting tsunami covered a huge area. the wave height reached 41 meters. The Fukushima-1 nuclear power plant was destroyed, radiation was released.

From earthquakes, tsunami waves and other events related to the earthquake. more than 20 thousand people died, more than 130 thousand buildings were destroyed and more than 300 thousand damaged.

A logical question arises, is not the repetition of the strange blue glow another sign that Japan will again be shaken by a powerful earthquake?
