Au Sable Forks is known for its repetitive history of floods, with those of 1996 and 2011 causing grievous damage – these were 15 and 18 feet above flood stage respectively. Since the 2011 flood caused by Hurricane Irene, ice jams, once common, have become less frequent because of the alteration in hydrogeology caused by the flood, which was the most massive one recorded. On April 20, 2002, a 5.0–5.3 Mw earthquake occurred north of the town. The shallow dip-slip shock had a maximum Mercalli intensity of VII (Very strong) and caused damage to roads, bridges, buildings, and chimneys.
