This study aims to discern the drivers of relative sea-level change at Lopud Island, distinguishing local tectonic from regional and global contributions. A detailed survey of sea-level markers (Lithophyllum rims and tidal notches) allowed the distinction of a seismotectonically uplifted sector, approximately 1 km in length, along the southern coast of Lopud Island (Southern Adriatic). The established high-resolution algal rim geochronology based on 23 radiocarbon dates enables distinction between the Late Holocene transgression periods and the seismically triggered regression events. Consequently, we distinguish here local tectonic uplift and provide the first reconstruction of the assumed number, timing, and displacements of past seismic events. The most important uplift of around 0.42 ± 0.10 m occurred in 1667 CE Dubrovnik earthquake while the earlier one of 0.15 ± 0.10 m, occurred probably between ~800 CE and ~ 1100 CE. The uplift of this coastal segment was also evidenced in tidal notches which are today ~0.25 ± 0.15 m above mean sea-level.

After correction for local coseismic displacements, the sea-level trends with full consideration of the available uncertainty were quantified using an Errors-In-Variables Integrated Gaussian Process model. The rates of RSL change vary between 0.2 and 0.7 mm/yr, with a mean of 0.4 mm/yr. The possibility of removing the local non-linear contribution, allows comparison of the obtained RSL curve with different glacio-isostatic model predictions. The obtained field based RSL records correspond well with the K33_j1b_WS9_6 model of Lambeck et al. (2011).

By distinguishing local non-linear RSL drivers (coseismic movements) from regional and global scale drivers we estimated a glacio-isostatic adjustment rate of ~0.34 mm/yr and a global common contribution of around 20 cm between 3.3 ka and 0.15 ka. This high-resolution study allows us to better approach the driving mechanisms of RSL change, thus providing new insight into the late Holocene sea-level history of this seismotectonically active sector of the Adriatic. Furthermore, this study reveals the precision of Lithophyllum rims in the studies of relative sea-level changes and demonstrates their potential in assessing palaeoearthquakes.

本研究旨在辨别 Lopud 岛相对海平面变化的驱动因素，区分当地构造与区域和全球贡献。海平面标记的详细调查（Lithophyllum边缘和潮汐槽口）允许区分沿着洛普德岛（南亚得里亚海）南部海岸的地震构造隆起部分，长约 1 公里。已建立的基于 23 个放射性碳日期的高分辨率藻缘地质年代学能够区分全新世晚期海侵时期和地震触发的回归事件。因此，我们在这里区分了局部构造抬升，并提供了对过去地震事件的假定数量、时间和位移的首次重建。大约 0.42 ± 0.10 m 的最重要隆起发生在 1667 CE Dubrovnik 地震中，而较早的 0.15 ± 0.10 m 可能发生在 ~800 CE 和 ~1100 CE 之间。该沿海段的隆起也在今天高于平均海平面约 0.25 ± 0.15 m 的潮汐槽中得到证实。

在对局部同震位移进行校正后，在充分考虑可用不确定性的情况下，使用变量误差综合高斯过程模型对海平面趋势进行量化。RSL 变化率在 0.2 到 0.7 毫米/年之间变化，平均为 0.4 毫米/年。去除局部非线性贡献的可能性允许将获得的 RSL 曲线与不同的冰川均衡模型预测进行比较。获得的基于现场的 RSL 记录与 Lambeck 等人的 K33_j1b_WS9_6 模型很好地对应。(2011)。

通过将局部非线性 RSL 驱动因素（同震运动）与区域和全球尺度驱动因素区分开来，我们估计冰川平衡调整率为 ~0.34 毫米/年，全球共同贡献约为 20 厘米，介于 3.3 ka 和 0.15 ka 之间。这项高分辨率研究使我们能够更好地研究 RSL 变化的驱动机制，从而为亚得里亚海这个地震构造活跃区的全新世晚期海平面历史提供新的见解。此外，这项研究揭示了石叶藻边缘在相对海平面变化研究中的精度，并证明了它们在评估古地震方面的潜力。
