The data in this study were taken from the Global CMT website in accordance with the coordinates of the earthquake point with the analysis method using the Coulomb stress method. The results of the Padan…
Beam-column joints are critical components in earthquake-resistant design, requiring careful consideration of seismic criteria due to their high sensitivity to seismic load distribution. This study investigates the performance of exterior beam-column joints with varying stirrup spacing under cyclic loading using nanocomposite polymer materials. The analysis was conducted using ANSYS, based on t…
Bangunan tinggi merupakan bangunan bertingkat banyak yang sangat dikhawatirkan akan menimbulkan dampak besar apabila mengalami kerusakan jika terjadi gempa bumi. Seperti hal nya kota Palembang yang semakin banyaknya pembangunan bangunan tinggi sehingga mulailah di fikirkan kembali apakah dengan palembang memiliki zona gempa 2 masih membutuhkan struktur yang tahan gempa mengingat zona 2 memiliki…
Indonesia merupakan negara kepulauan yang memiliki daerah gempa bumi yang cukup tinggi, karena terletak di pertemuan antara cirkum pasifik dan trans asiatik. Peristiwa bencana gempa bumi merupakan peristiwa yang terjadi dalam waktu ulang yang cukup lama tetapi tidak dapat dihindari, maka para peneliti hanya mencari solusi untuk mengurangi kerugian akibat yang terjadi dari gempa secara langsung …
Indonesia adalah daerah rawan gempa, untuk mengurangi resiko bencana diperlukan konstruksi bangunan tahan gempa. Hal ini dapat dicapai melalui perencanaan dan konstruksi yang baik yaitu dengan memperhitungkan suatu tingkat beban gempa rencana yang diharapkan dapat ditahan dengan baik oleh struktur pada umur rencananya. Sejarah peraturan mengenai kegempaan ini mulai diperkenalkan pada Perencanaa…
Gempa merupakan getaran atau guncangan yang terjadi akibat pergeseran lempeng - lempeng di lapisan bagian luar bumi, letusan gunung berapi, maupun akibat ledakan yang dibuat oleh manusia. Perhitungan beban akibat gempa harus diperhitungkan apabila mendesain struktur pada daerah rawan gempa terutama untuk bangunan tinggi (high rise building,) seperti gedung kantor Bank Mandiri Palembang yang mem…
Bangunan, khususnya rumah tinggal, merupakan prasarana fisik utama yang mutlak bagi kehidupan manusia, yang berfungsi memberikan tempat bagi mereka untuk tinggal maupun berkarya. Di tengah semakin meningkatnya kebutuhan manusia akan rumah, terhadap rumah yang layak huni dan handal secara teknis menjadikan keberadaan suatu rumah merupakan suatu keharusan. Pentingnya rumah tersebut semakin terasa…
Perencanaan gedung tahan gempa di Indonesia sangat penting karena sebagian besar wilayahnya merupakan wilayah gempa yang mempunyai intensitas rendah hingga tinggi. Indonesia ditetapkan dalam 6 wilayah gempa. Dimana wilayah gempa 1 adalah wilayah dengan kegempaan paling rendah dan wilayah 6 adalah wilayah dengan kegempaan paling tinggi. Untuk itu dilakukan studi pada 2 buah gedung, 2 lantai dan …
Secara umum, dalam perencanaan infrastruktur tahan gempa, terdapat beberapa jenis metoda analisis dengan tingkat kesulitan dan akurasi yang bervariasi. Sesuai dengan metoda analisis yang digunakan, parameter pergerakan tanah yang diperlukan untuk perhitungan dapat diwakili oleh percepatan tanah maksimum, respon spektra gempa, dan riwayat waktu percepatan gempa (time histories). Percepatan tanah…
Earthquake precursors using the earth's magnetic data by analyzing Ultra Low Frequency (ULF) emission anomalies is one of the earthquake disaster mitigation efforts. This study uses 11 earthquake data in the Province of West Sumatra and its surroundings in 2021 with coordinates (3.50ºLS-1.20ºN and 98.10º-102.10ºE). This study was conducted to determine Ultra Low Frequency (ULF) emission ano…
The research was conducted in Muba and its surroundings, South Sumatra. This area is included in the back arc basin which is not uncommon for geological disasters, one of which is an earthquake. The aim of this research is to identify the tectonic activity of the geological structure path associated with landform factors and to analyze the morphometric analysis of the drainage basin. The method…
The West Sumatra region is an active area of earthquake which is the result of the subduction of the Indo-Australian Plate with the Eurasian Plate. Precise hypocenter analysis is needed to understand about the accurate tectonic setting such as subduction zone in the area. To produce a more accurate hypocenter this hypocenter relocation is used to recalculate earthquake hypocenter by using the m…
It is a comprehensive and well illustrated textbook on all aspects of tsunami. I don't think there is any other book on the topic published. As one bookseller said after the Indian Ocean tsunami event, "I would have just filled my front window with copies and they would have walked out the store." This statement was just as relevant after the Japanese tsunami of 2011 and will be as relevant whe…
With increased climate variability, aggravated natural hazards in the form of extreme events are affecting the lives and livelihoods of many people. This work serves as a basis for formulating a ‘preparedness plan’ to ensure the effective policy formulation for planned development. Increased demand and competition with a high degree of variability have forced people to struggle in order to …
In the past, facilities considered to be at the end of their useful life were demolished and replaced with new ones that better met the functional requirements of modern society, including new safety standards. Humankind has recently recognised the threats to the environment and to our limited natural resources due to our relentless determination to destroy the old and build anew. With the awar…
The Tohoku earthquake on March 11, 2011, officially designated the “Off the Pacific Coast of Tohoku, Japan Earthquake” by the Japan Meteorological Agency caused an unprecedentedly severe disaster in the northeastern part (Tohoku) of the Japanese island of Honshu. This first volume of the series Natural Disaster Science and Mitigation Engineering: DPRI Reports covers various aspects of inves…
The classical field dealing with earthquakes is called “earthquake engineering” and considered to be a branch of structural engineering. In projects dealing with strategies for earthquake risk mitigation, urban planning approaches are often neglected. Today interventions are needed on a city, rather than a building, scale. This work deals with the impact of earthquakes, including also a bro…
Study of structures associated with shear zones is a crucial aspect to understand the deformation mechanism associated with such zones. Shear zones have been emphasized since it will lead to many latest applied studies such as radioactive waste disposal, groundwater flow etc. For the sake of brevity, research papers cannot show all possible variation in structures found in shear zones. The prop…
The occurrence of seismic events in glaciers has been an issue in the scientific literature since the early 1950s, following the report about icequakes in Baffin Island. Targeted seismological studies were undertaken by the Polish Expedition to Spitsbergen in 1962 and then continued at various glaciers in the Arctic, Antarctic and the Alps. The author of the book has been engaged in the project…
Pseudo-static analysis is still the most-used method to assess the stability of geotechnical systems that are exposed to earthquake forces. However, this method does not provide any information about the deformations and permanent displacements induced by seismic activity. Moreover, it is questionable to use this approach when geotechnical systems are affected by frequent and rare seismic event…
This book is a collective effort by world experts, bringing together assorted contributions presented during the Ocean Science Session OS-017, of the AOGS-AGU Joint Assembly held in Singapore in 2012 (the Asia Tsunami and Great East Japan Earthquake and Tsunami events) and other conferences. The chapters cover assessment, evaluation, forecast, policy and lessons learned as well as environmenta…
Seismic tomography was applied to estimate subsurface structures West Sumatera. Based on anomalies of P- dan S-wave velocity (Vp and Vs) and Vp-Vs ratio. Earthquake data were downloaded from ISC (International Seismological Center) website from January 1, 1900 to August 31, 2021. Earthquake events with a minimum of 3 phase were selected for tomography input. Seismic velocity models and source p…
