Coral reefs are active areas of scientific interest. Globally, coral reefs are declining due to enhanced sea surface temperature, rapid sea-level rise and other tectonic-climatic factors. In this paper, we have presented tectonic control for coral reef morphodynamics over the northern part of Andaman, Landfall Island. The 2004 Sumatra earthquake of $M_{\mathrm{w}}$ 9.1 posed essential changes on the overriding plate. Consequently, the Landfall Island changed its pattern of neotectonic movements. Here, we collected multi-temporal regional proxies like shoreline change rate, reef upliftment rate, and coral reef geomorphology for systematic tracking of earthquake-induced changes for various short-term [inter-seismic (1987–2004), co-seismic (2004–2006), early post-seismic (2006–2009), post-seismic (2009–2014)] and long-term [inter-seismic to post-seismic (1987–2014)] durations. Maximum upliftment rates (0.24 m/yr) and shoreline change rates (108.2 m/yr) with comparable geomorphic variations were noticed in co-seismic time. Other short-term changes are primarily related to earthquakes, wave actions and local geomorphology change. Additionally, we have reported new zones of adaptation for live corals. Our field survey and geodetic study verified remotely-derived morphologic adjustment of coral reefs.

珊瑚礁是具有科学兴趣的活跃区域。在全球范围内，由于海面温度升高、海平面快速上升和其他构造气候因素，珊瑚礁正在减少。在本文中，我们提出了对登陆岛安达曼北部珊瑚礁形态动力学的构造控制。2004年苏门答腊地震${米}_{\mathrm{瓦}}$9.1 对上盘进行了重大更改。因此，登陆岛改变了新构造运动的格局。在这里，我们收集了海岸线变化率、珊瑚礁抬升率和珊瑚礁地貌等多时间区域代理，以系统地跟踪各种短期地震引起的变化 [inter-seismic (1987–2004), co-seismic (2004) –2006)、震后早期 (2006–2009)、震后 (2009–2014)] 和长期 [震间到震后 (1987–2014)] 持续时间。在同震时间注意到具有可比地貌变化的最大抬升率 (0.24 m/yr) 和海岸线变化率 (108.2 m/yr)。其他短期变化主要与地震、波浪作用和当地地貌变化有关。此外，我们还报告了活珊瑚的新适应区。
