You need to read more carefully.
The writer doesn't say that gold is "created by earthquakes," either. He says "gold forms...."
From the abstract of the paper to which he refers:
"Flash vaporization continues as more fluid flows towards the newly expanded cavity, until the pressure in the cavity eventually recovers to ambient conditions. Multiple earthquakes progressively build economic-grade gold deposits."
Flash vaporization during earthquakes evidenced by gold deposits.
Gold forming is common terminology in the trade How Does Gold Form?
FReegards!
No, I read it correctly. The article clearly intended to misrepresent that paper's findings to suggest that gold is created by earthquakes. And as the citation you gave demonstrates, I was correct. It isn't.
