Abstract
The Air-Cooled Condenser (ACC) structure is one of the pivotal industrial buildings in Combined-Cycled Power Plants. This structure functions as a condenser of water steam, which is conveyed to it through the steam turbine generators, and accumulates the produced water and returns it to the plant’s main water circulation system. While the overall behavior of ACCs under earthquake is fairly known, important details such as the seismic response modification coefficient, R, have been a matter of controversy among the involved engineers. To address these ambiguities and in order to conduct a sure design, a more precise investigation of seismic behavior and response of these structures was deemed to be in demand. Answering this want, a numerical program was created in OpenSees numerical modeling platform to generate models for ACCs of different types, dimensions, and mechanical properties. The numerical results obtained from the analysis, especially for concrete ACCs, for whom investigation of their behaviour was thought to be more necessary, accorded well with the expected seismic behaviour foreseen for these buildings.

Abstract
This study investigates the surface deformation caused by the 28 March 2025 Myanmar earthquake (Mw 7.7) using Interferometric Synthetic Aperture Radar (InSAR) techniques with Sentinel-1 data. The earthquake, occurring along the Sagaing Fault, resulted in significant ground displacement, impacting infrastructure and communities. InSAR analysis reveals detailed deformation patterns, quantified through interferograms, multi-look processing, unwrapped phase data, and displacement maps. Results indicate a rupture zone extending approximately 110 km, with maximum subsidence of -0.82 meters and uplift of 0.18 meters, along the line of sight of satellite (LOS). These findings correlate with observed structural damage and provide insights into the fault's slip distribution. This study demonstrates the effectiveness of InSAR in assessing earthquake-induced deformation, offering valuable data for seismic hazard assessment, disaster response, and long-term resilience planning in this vulnerable region. The integration of satellite-based remote sensing with macroseismic data contributes to a comprehensive understanding of seismic events, supporting improved risk mitigation strategies.
