Mw 6.7 Costa Rica

On 13 November 2017 a strong earthquake occurred in Costa Rica at a depth of 10 km. The seismic event occurred at 02:28:22 UTC and had an estimated moment magnitude (Mw) 6.7.

It was the second strong earthquake in two days that followed on the Venus-Mercury-Neptune alignment on the 10th, while Earth was lining up with Venus and Jupiter, which may have somewhat contributed to the seismic increase, although the Earth-Venus-Jupiter alignment is generally not a very critical alignment. Of significance is the Moon's alignment with Neptune within days of the Venus-Mercury-Neptune alignment.
