An event chart for the 6.3 magnitude earthquake that hit Virginia and rippled up the eastern coast of the US up into Canada shows a lot of volatile energy on the Saturn- Moon axis (10th and 4th house).
Chiron conjuncted Neptune conjuncting the IC from 1:30 pm est to about 2 pm est. Possible self/home inflicted wound of a deceptive nature like a weapons test gone awry. Also the Sun in the midheaven opposing chiron and neptune leads me to believe this was an effect of Solar activity. The sun has been acting up as of late and solar flares are increasing in frequency.
