Just like the 1964 Alaska Good Friday earthquake and countless others this occured on Full Moon. Just a coincidence I’m sure…
It’s important on just how the sunlight is reflected off of the moon.
Probably just coincidence; there’s probably as many as fell on the first of the month or the 23rd or whatever.
If there is a lunar influence, it should happen at the moon’s nearest approach - its perigee. I took a look and the last perigee was on 1/21/23 (and will recur every 29 days or so). As it happens, it was the closest perigee on a new moon since the middle ages.
