The May 2006 Indonesian Earthquake
The diagram shows declination for the Moon and the planets in 2006. Click the image to enlarge.
Earthquakes often occur around planetary alignments such as New and Full Moon, eclipses and occultations.
They are also sensitive to the Moon's high declination (and extremes when out-of-bounds).
or to the Moon's distance as when at perigee (highest pull) or apogee (loser pull).
Data: 27 May 2006, 5h54 (26 May, 22h54 UT), 20 km south of Yogyakarta (7S57 - 110E20), Java. Magnit. 6.2
The quake occurred just hours before the New Moon and close to a series of Uranus occultations
happening at the declination corresponding to the earthquake and the volcano Merapi's earth latitude of 7°S.
All Moon-Uranus conjunctions between 27 March 2006 and 12 May 2007 are occultations of Uranus by the Moon.
The most recent Uranus occultation had occurred on 21 May (11h02 UT) at 14° Pisces and 7°S.
The following day, 22 May (14h12 UT), the Moon crossed the equator, and (15h24 UT) passed perigee at 1°Aries.
At the time of the earthquake, the Moon was out-of-bounds (25°N) moving towards the North lunistice (standstill).
Uranus had just passed Midheaven, the coming New Moon had risen, and Pluto was setting.
Note the 27 May New Moon (5h24 UT) at 5°48 Gemini almost squares Uranus at 14°30 Pisces.
Bare in mind, if you are new to this: a body's declination equals to a projection on earth latitude,
that is to say a declination of 7°S projects itself on the same latitudes - like those of Java and its Merapi volcano-.
