Abstract: Abstract Earthquakes of Mw ≥ 7 are usually followed by damaging aftershocks. The Mw ≥ 5 aftershocks tend to cause further damage to structures already weakened by the main shock. Using Omori’s Law modified by Utsu et al. (J Phys Earth 43(1):1–33, 1995) and the aftershock data for the first 44 days, within 500 km radius of the 6 February 2023 Turkiye earthquake, it was estimated that Mw ≥ 5 aftershocks may continue for 250 days (Rekapalli and Gupta in Nat Hazards 117(3):3399–3402, 2023). It is noted that Mw ≥ 5 aftershocks have continued for 191 days. No such aftershock has occurred since 16 August 2023.
