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.

Northridge cut a section out of the Santa Monica freeway, which took out a bunch of cable (I think by then it was mostly fiber) between USC and points west; that got Cerfnet's connections to several west LA customers (I worked for one of them in Culver City at the time). I kind of remember that they restored it by routing through Los Nettos. At home I was using the Cerfnet Caltech pop at the time, and had an outage for an hour or two (and lost power for about that long). The windstorm a few years later cut lots of above-ground fiber, though; lots more outages than any earthquake. I recall that CSUN was pretty well cut off (both net and roads) for a while. I don't recall if the Hector Mine quake cut any fiber but there is a repeater building near the railroad just east of the fault-line crossing. There wasn't a ground break that far north so the cables probably weathered it OK but the building might not have. (amazing to have a 7.4 or so quake that almost didn't injure anyone; almost all the damage was from the derail of the southwest chief westbound.)
