On 1 September 1886 a major earthquake occurred at Charleston, South Carolina. The seismic event occurred at 02:51 UTC and had an estimated moment magnitude (Mw) 7.3. It was an intraplate earthquake in a region not known to produce major earthquakes.
On 26 and 27 August 1886 Mercury lined up heliocentrically with Uranus and Jupiter respectively. Four days later the Moon lined up with both planets within three hours, resulting in a high lunar peak on the 31st reaching index 19. The earthquake occurred at the end of the peak. In addition, Venus made critical geometry on 30-31 December.
