From the earthquake in Myanmar, what do experts warn about high-rise buildings?

The recent 7.7-magnitude earthquake in Myanmar has raised significant concerns among experts regarding the resilience of high-rise buildings in seismically active regions. The disaster highlighted several critical issues:

1. Vulnerability Due to Construction Practices: Many high-rise buildings in Myanmar, particularly in rapidly urbanizing areas like Mandalay, were constructed using reinforced concrete without stringent adherence to earthquake-resistant standards. This has left them susceptible to structural failures during seismic events. Experts note that parts of Mandalay, situated along the Ayerwaddy River's floodplain, are especially vulnerable due to their geological setting. citeturn0search0

2. Inadequate Building Codes and Enforcement: The region's lag in implementing and enforcing comprehensive building codes contributes to the susceptibility of structures to earthquakes. This deficiency underscores the need for robust governance and regulatory frameworks to ensure that construction meets seismic safety standards. citeturn0search6

3. Impact on Neighboring Regions: The earthquake's effects extended beyond Myanmar, notably impacting Thailand. In Bangkok, approximately 600 miles from the epicenter, the tremors caused buildings to sway, resulting in panic and the evacuation of tall structures. A 30-story building under construction collapsed, tragically resulting in multiple fatalities and highlighting the potential risks associated with high-rise constructions in seismically active areas.

Expert Recommendations:

  • Strengthening Building Codes: Implement and rigorously enforce building codes that mandate earthquake-resistant designs, especially for high-rise constructions.

  • Retrofitting Existing Structures: Assess the seismic resilience of current buildings and retrofit them as necessary to withstand potential earthquakes.

  • Enhanced Urban Planning: Develop urban plans that consider seismic risks, potentially limiting the construction of high-rise buildings in the most vulnerable areas.

  • Public Awareness and Preparedness: Educate the public on earthquake safety measures and establish clear evacuation protocols to minimize casualties during seismic events.

Addressing these concerns is crucial to mitigate the risks posed by earthquakes to high-rise buildings in Myanmar and neighboring regions.
