Loma Prieta, very little; the UCSC line was a non-redundant T1 from San Jose BARRNET, and the other leaf nodes off that were down. As I recall the San Jose / SF to LA links were all golden. Phone service to Santa Cruz was down, then spotty, then up over the course of a day, but every line was jammed with people checking in so connect rates sucked. The UCSC point to point T1 had to be manually repaired I think. The telco lines had alternate routes for calls and made it work, in a bit. Northridge a few years later more or less flattened a C&W center just about at ground zero. CRL's pager-happy 24x7 MUD customer in Atlanta woke me up a minute later, and our lines through LA (and many others' lines) were down for a while. Dynamic routing was a little less dynamic then; I don't know what others did in great detail. CIX lists buzzed etc. I think that predates nanog as a list by a few months, but memory is fuzzy.

How widespread were the effects on backbone communication circuits from those quakes?

You should restate the "predates"; I was on console on earthquake.berkeley.edu at the time Loma Prieta let go, using among other things (then) Forumnet (now) ICB in a chat, and one of the immediate damage indications was that everyone at UC Santa Cruz dropped offline.
…and I was one of those people at UCSC, who had an interesting little adventure driving home to Berkeley the next day.
Also, there are probably people in Northridge and Napa who might dispute your definition of “major,” but yes,a I take your point.
