Astrology of volcano Sakurajima’s eruption in Japan

Sakurajima, one of Japan's most active volcanoes, experienced one of its most powerful eruptions in decades Sunday, sending an ash plume thousands of feet into the air. The volcano, located in the far southwestern part of Japan's mainland on the island of Kyushu, began to erupt at 4:31 p.m. local time Sunday (3:31 a.m. EDT U.S. time). The smoke plume eventually reached a height of 5,000 meters (approximately 16,000 feet), according to the Kagoshima Local Meteorological Observatory. Public broadcaster NHK reported it was the volcano's tallest ash plume since records began in 1955.

The chart shown above is the Sun’s ingress into sidereal Cancer. Note the powerful Pluto-Uranus square aspecting the meridian axis with Uranus on the fourth cusp – the point most associated with the earth and volcanic or seismic activity. The chart below is for the exact moment of  the eruption. Once again notice the Pluto-Uranus square on the other significant axis – the horizon. The Moon , which always acts as a fast moving trigger, is separating from a conjunction to Pluto and the Ascendant.

Pluto rules upheaval, breakdown and decay, but also regeneration and the purifying fire of catharsis. It reflects the archetypal Underworld--the dark, mysterious, and often terrifying reality which lurks beneath the surface of things, beneath our ego and societal conventions and the veneer of civilization, and which is periodically unleashed with great destructive and transformative force. Many of the problematic instincts that lie deep within the human psyche, such as murderous hatred, violent jealousy, compulsive greed and lust and so forth, reflect the activity of Pluto: this is Freud's broiling cauldron of the instincts. Pluto is visible in the elemental power of a volcanic eruption, of a devouring lion, of a war, of an orgasm, of a mother in the climactic stages of giving birth. It is present in all violent, purgatorial discharge of pent-up energies--from the Earth as in an earthquake, or from the human body and psyche as in therapy or in a psychotic break. Pluto is in many ways the polar complement of Neptune--together they represent the great polarities of Dionysus and Apollo, the chthonic and the transcendent, the volcanic and the oceanic, nature and spirit, instinct and imagination. And, like Neptune, Pluto is unfathomable. [1]

One potential manifestation of this transformational crisis of Pluto in Capricorn, if it is not brought to light and experienced fully by humanity itself, will be the increase of volcanic and seismic activity around the Pacific rim and elsewhere. [2]
