It’s their video title. In any event this is the 17 January 1994 Northridge Earthquake.
There was a quake on March 17, 2014 and I think those newsrooms are shown for that one.
Different event for the Northridge quake — which was also earlier in the morning — probably before some of those stations began morning newscasts.
Also, the news people shown are all relatively new and the lead-ins were much less sophisticated in 94.
