Hi Robynne, Volcanoes and volcanic regions are ruled by Pluto, now in an earth sign & Uranus also in earth. Earthquakes are ruled by Uranus and Pluto, both in earth signs. There is a Lunar Eclipse on July5, 2020, in 13Cp37'47" but doen't hit any NZ planets in that degree.
This Volcano was probably activated by Pluto in Capricorn within 2 degrees of the NZ IC.
The Fixed Star that was in angular parans for this event: Saturn in Capricorn was rising when fixed star POLLUX was setting....analysis...
