Abstract

Abstract – The 2023 Kahramanmaraş (Türkiye) doublets earthquakes (Mw 7.8 & 7.6) and the 2024

Myanmar earthquake (Mw 7.7) exhibited comparable seismic and structural damage characteristics, despite

differences in regional construction practices. This study focuses on the recurrence of soft/weak story

collapses observed in both events. Additionally, both earthquakes triggered multiple aftershocks exceeding

magnitude 6.0, exacerbating the damage and hindering emergency responses. The study highlights the

progressive collapse of the Chatuchak high-rise tower in Myanmar, which likely failed due to soft-story

irregularity. Through comparative analysis of seismic parameters and field damage patterns, this study

underlines the urgency of addressing structural irregularities in mid- and high-rise buildings across

seismically active regions. Recommendations are provided for enhancing design and retrofit strategies in

accordance with lessons learned from these disasters.
