M3.9 aftershock to Duncan earthquake A magnitude 3.9 earthquake that hit just before 4 p.m. today is the largest aftershock so far following Saturday's M5.3 Duncan earthquake near the New Mexico border.   [Right, the main shock and all aftershocks greater than magnitude 3.0,  including the latest event in orange.  Credit, USGS]    As of 7:30 p.m. tonight, 13 people reported having felt this latest aftershock.

We expect aftershocks to continue for weeks and possibly months.
