The single most important signifier of earthquake a ctivity is the position of the Moon’s nodes and turnings in the horoscope, in either the zodiac or composite charts or both. Tectonic activity is thereby signified by the position of horoscope components correspond to the latitude relationship between the Sun and the Moon. Each ‘turning’ represents the point of intersection between the ascending and descending nodes and lies where the differential between solar and lunar latitude would be greatest were the Sun and the Moon to occupy the given degree. In earthquake horoscopes, either one or more node or turning will be emphasised by the presence of other horoscope components and/or one or both axes will be the focus of mid-point aspects. The Moon’s nodes or turnings may also be significantly positioned otherwise, for instance in the horoscope for the 1970 Chimbote earthquake where the placement of the Moon’s higher turning is close to the Sun but partakes of a linear sequence which the Sun is excluded from.
Earthquakes frequently occur when conjunctions arise, particularly between the Ascendant, Descendant, Medium Coeli or Imum Coeli and the Sun, the planets, the Moon’s nodes or the turnings, and when the house positions of horoscope components, particularly the Moon, the Moon’s phase, and the ‘personal points’, join with elements of the actual zodiac placements of other horoscope components. The relationship between fast
transits and earthquake activity is consistent with the nature of earthquakes, as conjunctions which arise from the Earth’s daily cycle represent the activation of tension accumulating over a long period of time. Although earthquakes often occur when the horoscope presents energy concentrated in conjunctions or stelliums, in horoscopes corresponding to earthquake events the strength represented by the Sun, as well as conjunctions and stelliums, is rarely stabilised within mid-point aspects.
It is hoped that once appropriate software is available to model astrological phenomena, the date and time of an earthquake, volcano, or tsunami may be accurately predicted and the necessary precautions followed, in the event that other conditions indicate the likelihood of seismic activity in the near future.
The greatest earthquakes in recent history
For night charts, the sunrise of the following morning and the sunset of the preceding evening are used to calculate ascendant and descendant figures. For day charts, the sunrise of the preceding morning and the sunset of the following evening are used to calculate these. Ascendant and Descendant values therefore represent the ecliptic position in the direction of the closest sunrise or sunset event rather than the actual ecliptic position which would visibly intersect the horizon at the time of the chart. This level of approximation is consistent with available sunrise and sunset data, which is accurate to the nearest minute.
The Sun’s mean, apparent size is approximately 32 arcminutes. However, atmospheric refraction declines by approximately 5 arcminutes throughout sunrise, and increases by approximately 5 arcminutes throughout sunset, therefore at sunrise and sunset, the duration of sunrise or sunset at the equator is equivalent to 37 arcminutes of ecliptic progression. Sunrise or sunset will last approximately 2 minutes between latitudes of 0 and 9°22, 3 minutes between latitudes of 9°22 and 45°12, and 4 minutes between latitudes of 45°12 and 62°29. In the tropics, the upper edge of the sun will appear on the horizon approximately 1 minute in advance of its centre. Therefore, the official time of sunrise in the tropics will be approximately 1 minute in advance of the time of sunrise for the purpose of this study. To the nearest minute, the official time of sunrise and sunset will precede or follow – for astrological purposes – sunrise or sunset, respectively, by 2 minutes at latitudes between 35°41 and 60°27 and by 3 minutes at latitudes between 60°27 and 69°22.
To calculate the point of the ecliptic which intersects the horizon if atmospheric refraction is to be discounted, the equation 31.5/Sin(90-latitude°) is used. This gives the ecliptic space intervening the apparent and non-apparent events. The result must be subtracted from the Ascendant value and added to the Descendant value to provide Ascendant and Descendant values exclusive of the effects of atmospheric refraction.
