Eruption of Mount St Helens — birth chart across three traditions

Born: 1980-05-18 at 08:32 · Mount St Helens, Washington, USA

Data source: Rodden AA (seismograph record of the magnitude 5.1 earthquake that triggered the collapse).

A magnitude 5.1 earthquake brought down the mountain's north face and opened the lateral blast. Pacific Daylight Time was UT-7 in May, so 08:32 local is UT 15:32.

Reading the chart

Taurus Sun, Cancer Moon, Cancer rising — a day chart, led by the Sun's agenda.

Moon carries unusual weight here — rules the Ascendant sign (Cancer); in an angular house (1).

Stellium in Virgo: Mars, Jupiter, Saturn — a concentrated emphasis that colors the whole chart.

Water is the leading element (44% weighted), while fire is least emphasized — a texture worth noticing, not a verdict.

Mutable modality leads: the chart's default rhythm is adapting — adjusting and redistributing energy.

Chart ruler: Moon in Cancer, house 1 — where this planet acts, the chart's agenda advances.

Planetary distribution: locomotive — planets cover two-thirds of the wheel; the leading planet drives the chart.

Sun at 27°50′ Taurus, house 11: core identity, vitality and sense of purpose operates steadily, sensually, with a taste for the durable — the keynote is consolidation. The main arena is friends, groups, networks and long-range hopes.

Moon at 21°34′ Cancer, house 1: emotional life, instinct and the need for safety operates protectively, tidally, by feel and memory — the keynote is belonging. The main arena is self-presentation, body and beginnings. In its own domicile: it acts with full native resources.

Stellium in Virgo: Mars, Jupiter, Saturn — a concentrated emphasis that colors the whole chart.

Mercury square Mars (orb 0°31′, applying): Mercury and Mars grind productively — friction between these functions builds real capacity when worked.

Sun opposition Vertex (orb 1°17′, applying): Sun and Vertex face each other across an axis — awareness tends to arrive through other people and counterweights.

Moon square Pluto (orb 2°09′, separating): Moon and Pluto grind productively — friction between these functions builds real capacity when worked.
