Probabilistic seismic hazard analysis for Bagan (Myanmar)
A probabilistic seismic hazard analysis for Bagan, Myanmar, reveals significant underestimation of seismic risk in the region. The study, conducted post-2016 Chauk earthquake, found peak ground acceleration values ranging from 0.25 to 0.36 g for a return period of 2475 years, indicating higher hazard levels than previously estimated. Researchers developed two seismic source models and utilized state-of-the-art ground motion models to assess the seismic vulnerability of 43 temples, incorporating local soil information. The analysis, based on instrumental and historical earthquake records, underscores the need for updated hazard maps and site-specific uniform hazard spectra to mitigate risks to Bagan's historic structures.
Remote sensing-based deformation monitoring of pagodas at the Bagan cultural heritage site, Myanmar
A study employing high-resolution TerraSAR-X imagery identified millimetric-scale deformation hotspots and displacement anomalies in pagodas at the Bagan World Heritage site, linking them to land cover changes and seismic activity. By combining small baseline subset (SBAS) and persistent scatterer synthetic aperture radar interferometry (PSInSAR), researchers achieved precise monitoring across both landscape and monument scales—critical for heritage protection and sustainable development. This non-contact method offers a robust alternative where traditional field-based surveillance is limited, providing valuable insights into the structural stability of this culturally significant site.
Built Heritage Documentation and Management: An Integrated Conservation Approach in Bagan
A multidisciplinary approach to heritage documentation has proven effective in assessing and managing the conservation of vulnerable UNESCO World Heritage Sites, such as Bagan. The study demonstrates that integrating diverse documentation techniques—including both image-based and non-image-based methods—can provide a robust foundation for monitoring and retrofitting actions, particularly in regions prone to natural disasters like seismic events and flooding. By documenting four temples in Bagan, researchers tested the flexibility of their methodology, evaluating its strengths and limitations across different architectural designs. This work also emphasized capacity-building efforts, training local professionals and archaeologists in advanced digital documentation techniques, thereby enhancing technical knowledge and on-site expertise.
