My local station, KUSI said that it didn’t seem to have that much affect in San Diego, but they were still watching for it in the LA area beaches.
But, the latest is .. there was nothing to report.
It could be that the quake was not that deep .. but I don’t have the stats on that.
As I recall, the depth of the big quake was 16 miles down and the most shallow aftershock was 6.2 miles down. Deep but not unusually deep. The Boxing Day Quake was, as you say, very shallow with a lot of underwater ground movement.
