Tambakrejo Beach in Blitar Regency is classified as an area that is very vulnerable to tsunami catastrophes. Many researchers have conducted studies on regions impacted by the tsunami. However, more studies into the link between the outcomes of social and spatial studies still need to be carried out because these are two different perspectives with different parameters and variables. The novel approach in this research involves delineating tsunami-affected areas and assessing population capacity in coastal regions. The hazard maps and livelihood asset variables using grid cells of a specific size have been used to identify risk levels. The grid cells used are 50 m × 50 m² so that they are expected to represent the minor units on the face of the earth, such as buildings, assets, property or land parcels, for capacity assessments or measuring the level of threat to disasters and are no longer based on regional administrative boundaries.
The research results show that using grid cells to analyse areas affected by the tsunami can provide excellent and informative results. Research findings at the research location regarding community preparedness in facing tsunamis show that communities at risk of being affected by the tsunami need to increase their capacity because the majority of communities in coastal areas, especially in the Sidorejo sub-village, have been identified as having low capacity according to several livelihood asset parameters such as financial capital in income. By increasing individual capacity, it is hoped that society will be able to avoid the threat of tsunami waves better.
勿里达县的坦巴克雷霍海滩被归类为极易遭受海啸灾难的地区。许多研究人员对受海啸影响的地区进行了研究。然而，仍需对社会研究结果与空间研究结果之间的联系进行更多研究，因为这是两个具有不同参数和变量的不同视角。本研究中的新方法包括划定海啸影响区域并评估沿海地区的人口容量。利用特定大小的网格单元绘制的灾害地图和生计资产变量已被用于识别风险水平。所使用的网格单元为50米×50平方米，因此预计它们能代表地球表面的微小单元，如建筑物、资产、财产或地块，用于容量评估或衡量灾害威胁程度，且不再基于区域行政边界。
研究结果表明，使用网格单元分析受海啸影响的区域能够提供出色且信息丰富的结果。研究地点关于社区应对海啸准备情况的研究结果表明，面临海啸影响风险的社区需要提高自身能力，因为根据一些生计资产参数，如收入中的金融资本，沿海地区的大多数社区，尤其是西多雷霍村的社区，已被确定能力较低。通过提高个人能力，希望社会能够更好地避免海啸波的威胁。
