Orphaned references in 1987 Superstition Hills earthquakes
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of 1987 Superstition Hills earthquakes's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "ISC-GEM": From 1992 Big Bear earthquake:  From 2003 San Simeon earthquake:  From 1981 Westmorland earthquake:  From 1933 Long Beach earthquake:  From 1990 Upland earthquake:  From 1999 Hector Mine earthquake:  From 1987 Ecuador earthquakes:  From 1973 Point Mugu earthquake: </li> <li>From 1931 Valentine earthquake: </li> </ul>

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 08:53, 21 November 2020 (UTC)
