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.
