As predicted by me in my post earlier today, a pair (ha!) of magnitude 5+ earthquakes hit off the Sandwich Islands (ha?) today. One happened at 08:46:32 UTC (before I posted, but I didn't know at the time) and another, slightly stronger, at 17:04:50 UT.
There was a bigger one -- magnitude 6.5 -- off the coast of Taiwan, but that was much earlier today, actually yesterday evening US time, so I don't count that one. But who knows? The day's not over yet.
