The recent earthquake in Myanmar on March 28, 2025, that also significantly affected parts of northern Thailand and Bangkok has raised concerns about building safety and structural resilience in Thailand. This event has reminded building owners and possessors in Thailand of the necessity of understanding earthquake-resistant building standards, their legal obligations regarding structural inspections, and compliance requirements under Thai law. Under Thai law, building owners and possessors have specific responsibilities regarding the structural integrity of their properties, particularly in areas prone to seismic activity. This article lays out the key legal requirements and outlines the potential penalties for noncompliance. Structural Design and Earthquake Resistance Requirements With respect to standards regarding earthquake resistance, Thailand’s Ministry of Interior has issued the Ministerial Regulation on Load Bearing, Durability, and Resistance of Buildings and Soil Foundations to Earthquake Forces B.E. 2564 (2021), replacing a previous ministerial regulation from 2007. The current ministerial regulation prescribes certain types of buildings in 43 designated provinces to comply with seismic design standards. These 43 provinces can be categorized into three main zones: Zone 1: Areas requiring monitoring due to the potential for impact on the structural integrity and stability of buildings when exposed to seismic waves, consisting of 14 provinces (e.g., Krabi, Surat Thani, Prachuap Khiri Khan, etc.). Zone 2: Areas where there may be moderate impact on the structural integrity and stability of buildings when exposed to seismic waves, consisting of 17 provinces (e.g., Bangkok, Nonthaburi, etc.) Zone 3: Areas where there may be significant impact on the structural integrity and stability of buildings when exposed to seismic waves, consisting of 12 provinces (e.g., Chiang Mai, Chiang Rai, Kanchanaburi, etc.) For buildings located in these categorized zones, the geometric configuration of the building structure must be designed to ensure stability in resisting seismic waves. Additionally, structural
