Mw 6.6 Jujuy, Argentina
updated 1 June 2021 UTC

On 11 February 2015 a strong earthquake occurred in Jujuy, Argentina at a depth of 180km. The seismic event occurred at 18:57:18 UTC and had an estimated moment magnitude (Mw) 6.6.

Three planetary alignments preceded the earthquake, most notably Mercury-Venus-Uranus on the 10th. Lunar geometry was quite low with only a geometry index 8 throughout the week. However, no less than 5 WPG peaks from the 7th to the 11th occurred before the earthquake, which set the stage for additional larger seismic activity, which indeed occurred on the 13th and 16th.
