Resumo: | The Sumatra-Andaman earthquake that occurred on December 26, 2004 was the second largest earthquake in the past 40 years, with a moment magnitude of 9.1 - 9.3. The rupture took place at a depth of 1.3 km along a large boundary fault between the Indian and Burma plates. The fault slip reached up to 20 meters near Banda Aceh, Sumatra Island, and was more rapid compared to the northern end between the Indian Plate and the Andaman archipelago, where landslide took almost one hour to reach from 7 to 20 meters. Based on this data and other observations, it was possible to estimate that the main tsunami originated approximately 390 km from Banda Aceh city. Although the energy transmitted by the simple harmonic waves adopted in this study was shorter than that reported by other references, it was still significant. The estimated arrival time for the tsunami in Banda Aceh using a simple model was reasonably consistent with the actual observation time. This agreement suggests that the origin region of the estimated in this study is likely within the most probable starting point of the tsunami. The wave amplitude near the coast, as estimated by the model, fell within the observed range reported by the references. The methodology developed in this study seems to be suitable for obtaining initial estimates of several important parameters involved in events of this nature. |

La ruptura ocurrió a una profundidad de 1.3 km a lo largo de una gran porción do límite de la falla entre las placas indiana y birmana. Cerca de Banda Aceh, en la isla de Sumatra, se produjo un deslizamiento de falla de hasta 20 metros, que fue más rápido en comparación con el extremo norte entre la placa indiana y el archipiélago de Andamán, donde el deslizamiento tomó casi una hora para deslizar 7 a 20 m. Con estos datos y otras observaciones, pudimos estimar que el principal tsunami tuvo su a aproximadamente 390 km de la ciudad de Banda Aceh. A pesar de que a energía transmitida por las ondas armónicas simples adoptadas en este estudio fue más corta que la informada por las otras referencias, todavía así, ella es significativa. El tiempo estimado de llegada del tsunami a Banda Aceh utilizando el modelo simple fue razonablemente consistente con el tiempo de observación real. El tiempo de llegada de la onda sugiere que la región de origen de la onda estimada en este estudio parece estar próxima de la región principal donde ocurrió el fenómeno. La amplitud de la onda cerca de la costa, estimada por el modelo, se encontraba dentro de la faja observada por las referencias. La metodología aquí desarrollada parece ser adecuada para [...]O terremoto de Sumatra-Andaman que ocorreu em 26 de dezembro de 2004 foi o segundo maior terremoto dos últimos 40 anos, com uma magnitude de momento entre 9,1 e 9,3. A ruptura ocorreu a uma profundidade de 1,3 km ao longo de uma grande falha de fronteira entre as placas Indiana e de Burma. O deslizamento da falha atingiu até 20 metros perto de Banda Aceh, na ilha de Sumatra, e foi mais rápido em comparação com a extremidade norte entre a placa Indiana e o arquipélago de Andaman, onde o deslizamento levou quase uma hora para atingir de 7 a 20 m. Com base nesses dados e outras observações, foi possível estimar que o principal tsunami teve sua origem a aproximadamente 390 km da cidade de Banda Aceh. Embora a energia transmitida pelas ondas harmônicas simples adotadas neste estudo tenha sido menor do que a relatada por outras referências, ainda assim, ela foi significativa. O tempo estimado de chegada do tsunami em Banda Aceh usando o modelo simples foi razoavelmente consistente com o tempo de observação real. Entre os tempos de chegada da onda sugere que a região de origem da onda estimada nesse estudo parece estar próxima da região onde efetivamente o fenômeno ocorreu. A amplitude da onda próxima à costa, conforme estimada pelo modelo, ficou dentro da faixa observada relatada pelas referências. A metodologia aqui desenvolvida parece ser adequada para obter estimativas iniciais de vários parâmetros de importância em eventos dessa natureza.Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Sul2023-12-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo avaliado pelos paresapplication/pdfhttps://periodicos.ifrs.edu.br/index.php/REMAT/article/view/664510.35819/remat2023v9i2id6645REMAT: Revista Eletrônica da Matemática; Vol. 9 No. 2 (2023); e3007REMAT: Revista Eletrônica da Matemática; Vol. 9 Núm. 2 (2023); e3007REMAT: Revista Eletrônica da Matemática; v. 9 n. 2 (2023); e30072447-2689reponame:Remat (Bento Gonçalves)instname:Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Sul (IFRS)instacron:IFRSenghttps://periodicos.ifrs.edu.br/index.php/REMAT/article/view/6645/3492Copyright (c) 2023 REMAT: Revista Eletrônica da Matemáticahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAraújo, Jorge Corrêa deMárquez, Rosa García2023-12-23T01:50:13Zoai:ojs2.periodicos.ifrs.edu.br:article/6645Revistahttp://periodicos.ifrs.edu.br/index.php/REMATPUBhttps://periodicos.ifrs.edu.br/index.php/REMAT/oai||greice.andreis@caxias.ifrs.edu.br2447-26892447-2689opendoar:2023-12-23T01:50:13Remat (Bento Gonçalves) - Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Sul (IFRS)false |
