Note
USGS recorded an M6.7 earthquake at 05:44 UTC (1:44 AM ET) on October 13 on the central Mid-Atlantic Ridge near the equator, and an M6.8 at 12:23 UTC (8:23 AM ET) about 60 km away, both at about 10 km depth. Both carry green PAGER alerts. GDACS rates the M6.8 as low humanitarian impact with a maximum tsunami wave alert of 0 m.
Nothing to brace for. Something to notice.
Why it matters
Mid-ocean ridge quakes rarely hurt anyone. A strong doublet is still a reminder that the plates move on their own schedule.
