“…Kondisi ini tentu akan merugikan mengingat anak adalah penerus bangsa yang akan diharapkan melanjutkan pembangunan. Salah satu langkah yang ditempuh dalam membangun pengetahuan dan kesadaran anak dalam bertindak ketika peristiwa bencana terjadi adalah melalui pendidikan yang efektif dan akan menjadi bagian dari investasi masa depan (Imamura, Penmellen, Suppasri, & Muhari, 2019).…”

Penelitian ini bermaksud membuktikan adanya pengaruh buku cerita bergambar berkaitan dengan pengetahuan manajemen bencana anak. Adapun metode penelitiannya merupakan eksperimen dengan bentuk quasi eksperimental design. Teknik pengambilan sampel dengan purposive sampling dengan jumlah 48 anak yang berada pada usia 5-6 tahun. Data pengetahuan manajemen bencana anak dikumpulkan dengan menggunakan tes pengetahuan tentang manajemen bencana. Adapun hasil dari studi ditemukan pengaruh buku cerita bergambar berkenaan dengan pengetahuan manajemen bencana pada anak. Dengan nilai thitung= 25,790 dan probabilitas sig t= 0,000. Buku cerita bergambar memberikan pengaruh terhadap pengetahuan manajemen bencana pada anak sebesar 55,94%. Kebaruan yang diperoleh dari penelitian ini adalah pentingnya memperkenalkan manajemen bencana kepada anak usia dini melalui sumber bacaan yang memiliki gambar sehingga pesan yang terdapat pada buku tersebut dapat tersampaikan dengan baik.

“…The impact of earthquake-induced tsunamis on coastal communities are enormous in both human and socio-economic costs (Suppasri et al 2015;Imamura et al 2019). Earthquake induced tsunamis are a potential threat to countries located at the tectonic plate junctions (Murty et al 2006).…”

This paper explores the influence of onshore structures' orientations and arrangements during tsunami impact using the numerical method of smoothed particle hydrodynamics (SPH). Observations from previous tsunami events often reveal variation in the damage and survivability of impacted similar structures. Such variation can be due to shielding effects and other interactions that occur when the tsunami wave is incident upon an urbanised location. The SPH model used in this work was first validated against previous experimental results and was then used to explore the resulting hydrodynamic behaviour to a level of detail hitherto unobtainable from physical experiments. Groups of three and five structures were modelled with varying spatial separation and orientation to the incoming tsunami bore, characterised by the wake clearance angle (A) and the rotation angle (R), respectively. The results reveal significant reductions in total force on a structure can be made via strategic spatial positioning and orientation. Such reductions may mean the difference between superficial damage and wholesale structural collapse and allow the development of more resilient structures in tsunami-prone regions.

“…Tsunami hazard and risk assessments provide crucial decision-support tools to inform disaster resilience in coastal locations, particularly in the context of preparedness, evacuation and land-use planning [1][2][3][4][5][6]. Indeed, with global tsunami-related casualties and damages estimated to be one hundred times greater between 1998 and 2017 compared to the preceding 20 year period, due largely to the 2004 Indian Ocean and 2011 Tohoku-oki tsunamis [7], the need for hazard risk information in tsunami-prone regions is essential (e.g., [8,9]).…”

Multiscale Quantification of Tsunami Hazard Exposure in a Pacific Small Island Developing State: The Case of Samoa

et al. 2021

This study presents a scenario-based approach for identifying and comparing tsunami exposure across different sociopolitical scales. In Samoa, a country with a high threat to local tsunamis, we apply scenarios for the 2009 South Pacific tsunami inundation at different grid resolutions (50 and 10 m) to quantify building and road exposure at the national, district and village levels. We show that while the coarser 50 m model is adequate for use in the rapid identification of exposure at the national and district levels, it can overestimate exposure by up to three times more at the village level. Overestimation typically occurs in areas characterized by flat, low-lying, gentle-rising terrain. Overall, a 35% increase in buildings exposed to the 50 m model is observed compared with the 10 m scenario on southeast Upolu island. Similarly, a 31% increase in road exposure is observed for the 50 m scenario. These observations are discussed within the context of tsunami evacuation planning and logistics. Notwithstanding the variability in exposure, a precautionary approach leads us to conclude that while higher-resolution models are recommended where available data and/or financial resources permit, the absence of such datasets should not preclude the use of coarser hazard datasets in risk assessments. Finer-resolution models provide more credence in detailed local-level exposure evaluation. While the results of this study are specific to the Samoan context, the results can be applied to the multiscale assessment of tsunami risk exposure in similar hazard contexts.
