Bangkok is built on a muddy floodplain. The soft ground accentuates the ground motion by the jello-wobble resonance effect. High-rise buildings that do not have seismic isolation or counter-weight damping (like Taipei 101) will suffer dramatic whiplash shaking at the top. https://www.atlasobscura.com/places/tuned-mass-damper-of-taipei-101 https://www.atlasobscura.com/places/tuned-mass-damper-of-tai... Some cities closer to the epicenter, such as Chiang Mai, are also on floodplains, but have many fewer high-rise buildings. Some smaller condo blocks there have been deemed unsafe after the earthquake. https://www.chiangmaicitylife.com/citynews/general/following-earthquake-four-buildings-deemed-unsafe-until-further-inspection/ https://www.chiangmaicitylife.com/citynews/general/following...
