Big Quakes Straddle the IDL

Two major quakes occurred today within a couple of degrees of the International Dateline: first a 6.9 magnitude quake, quickly followed by a 6.6 quake, rocked the southern reaches of the line just north of New Zealand and the northern quake, with 10 times more ground movement at 7.9, shook up the western Aleutians of Alaska just to the east of the dateline and sent tsunami warnings flying around and across the Pacific .  Tsunami warnings for both big quakes have now been cancelled with sea level changes of less than a foot even near the epicenters.  Aftershocks continue with great frequency in both regions making today's USGS list rather lengthy and almost constantly updating as new shakes occur.  If you're not near the line where the old day ends and the new begins you are likely in a quiet zone today, but if you are reading this from earth, just remember that could change...at most any time, Today On Earth.
