… West of the Moon.
From Leon Knopoff’s obituary in the LA Times:
He also gained a certain amount of fame from a 1983 report in the journal Nature with astronomer Steven Kilston that tentatively linked earthquakes to an alignment of the sun and moon on opposite sides of the Earth that tugged the opposite sides of faults in opposing directions. That article predicted a quake in November 1987 in California’s Imperial Valley and, in fact, two occurred.
Researchers still do not know what to make of that potential link.
