Let's get even more specific on this nuance. On August 24, 2014 - almost 25 years from the major Loma Prieta quake of 1989, a magnitude 6.0 happened in Napa (the city, within the county) at about 2:30 am. That was early on a Sunday morning, and by coincidence, I'd woken up a few minutes before that event (pee break), and was still wide awake when it hit. I live on the Peninsula, about 55 miles south as the crow flies, and it nearly jolted me out of bed. So I grabbed for my little bedside radio and started dialing around. KGO was on autopilot, KQED too, and KCBS was running one of those canned "CBS News in Review" programs. It took their overnight anchor close to 15 minutes to get the station out of autopilot and back live - he was probably having a lunch break - and start taking calls from listeners and their own newspeople, who immediately swung into coverage mode and started hitting the ground to file live phoners.
There was a time when KGO would have been live and local, and would have immediately started taking calls from listeners. The value of the callers' testimony was sorta limited, but at least the anecdotal reports of perceived strength and damage (or lack thereof) across the vast listening area helped quantify how big an event it had been until the USGS could publish something official. But KGO by then was a shell of its pre-2011 self.
Back then, KQED had been running off their server 11pm-5pm 7 night a week, and NPR's Weekend Edition didn't start until 5am, so there was no local coverage until someone got into the building sometime in the 4am hour. In fact, they were caught so flatfooted, and were so embarrassed, that they re-staffed the overnight hours and to this day have that shift covered.
And in an admirable example of "No Good Deed Going Unpunished", that KCBS anchor, who was caught with his pants down - I'm guessing literally, in a bathroom stall, thinking he still had a half hour for his "biobreak" - was laid off a month or two later. I won't mention a name, but he was a station veteran.
So yeah, quakes do happen in the middle of the night, and they wake people up, and on occasion cause damage, injury and even loss of life. But if a tree falls in the forest and there's no live body left to report on it, does the medium retain any credibility?
