| Popis: | The Bangkok is undergone subsidence from land subsidence, tectonic motion and sea level rise. INSAR result show that Bangkok subsided from 15-25 mm/yr. GPS results show that Bangkok is still undergoing post-seismic tectonic deformations from the 2004 Mw 9.2 earthquake, with a significant change in vertical motion: from quasi-linear uplift at 6 ± 1 mm/yr to (temporary) non-linear subsidence rates of 5-10 mm/yr in the first 7 quake aftermath years. Based on satellite altimetry data, the absolute sea-level rise in the Gulf of Thailand is estimated at 5-6 mm/yr. Ground water induced subsidence and implications are also investigated. This paper presents results from an ongoing study. The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) |
