I have experienced a 7.1 here in SoCal, but the epicenter was about 50 miles away. Still, it was scary enough that I grabbed my purse and ran out the door toward my car in the parking lot (where nothing can fall on you).
I’ve been at the epicenter of some pretty good shakers; the Whitter Narrows quake of 1987 comes to mind when thinking of this quake; unreinforced masonry buildings at the epicenter with a shallow depth of 8 miles (It was a 5.9.)
Considering the building standards in California, I would not want to imagine being in Italy (6.2 vs 5.9) with an even shallower quake (6 miles instead of nearly 9) with a higher magnitude.
I hope that most survived with just scrapes and bruises but rationally, three died in Whittier directly from the quake, and five more from associated events, so I’m going to really believe the PAGER assumption that the deaths will most likely be in the dozens if not hundreds and that at least hundreds if not thousands of unreinforced heritage buildings failed during this quake.
I went thru both Sylmar quakes and many others.
