Efficient computer programming is becoming a central requirement in quantitative Earth science education. This applies not only to the early career stage but—due to the rapid evolution of programming paradigms—also throughout professional life. At universities, workshops, or any software training events, efficient practical programming exercises are hampered by the heterogeneity of hardware and software setups of participants. Jupyter notebooks offer an attractive solution by providing a platform‐independent concept and allowing the combination of text‐editing, program execution, and plotting. Here, we document a growing library with dozens of Jupyter notebooks for training in seismology. The library is made “live” through a server that allows accessing and running the notebooks in the browser on any system (PC, laptop, tablet, smartphone), provided there is internet access. The library seismo‐live contains notebooks on many aspects of seismology, including data processing, computational seismology, and earthquake physics, as well as reproducible papers and graphics. It is a community effort and is intended to benefit from continuous interaction with seismologists around the world.
Aktifitas seismik Sesar Matano sangat tinggi di mana gempabumi sering dirasakan masyarakat dan mengakibatkan kerusakan di area sekitarnya. Identifikasi aktifitas gempabumi dengan mengetahui besarnya energi yang dilepaskan di 6 segmen pada Sesar Matano diperlukan untuk perencanaan mitigasi gempabumi. Dilakukan juga estimasi periode ulang gempabumi yang akan terjadi disertai kemungkinan energi yang akan dilepaskan oleh gempabumi di masa yang akan datang. Data yang digunakan adalah katalog gempabumi EHB dan BMKG tahun 1961-2019. Energi gempabumi dihitung dengan mengkonversikan nilai momen seismik ke dalam energi fisis gempabumi. Sedangkan nilai momen seismik didapatkan dari konversi magnitudo gempabumi. Nilai periode ulang didapatkan dengan membagi nilai slip rata-rata terhadap sliprate. Berdasarkan hasil pengolahan data yang dilakukan di 6 segmen berbeda, yaitu Segmen Kuleana, Pewusai, Matano, Pamsoa, Ballawai, dan Garessa masing-masing memiliki nilai potensi magnitudo maksimum yang sedikit berbeda dengan magnitudo maksimum yang dikeluarkan PUSGEN. Semakin besar potensi magnitudo maksimumnya, maka semakin lama pula potensi gempa tersebut akan kembali berulang.
Investigation of soil is important to do in the planning of building construction such as foundations, piles, roads, etc. To find out the bearing capacity and parameters of the soil where a building will be built. Investigation of the soil can be done in various ways, one of which uses an electrical cone penetration test with pore water pressure. In the embankment project for the calculations on the soil so that it can be known about the settlement in soil and the length of time it reaches the hydrostatic level. Cone penetraton test is reqired and the results produce data in the form of cone resistance (qc), blanket friction (fs) and pore pressure (u) which will be processed in the CPET-IT program in order to produce soil parameters that will be used for soil settlement analysis. To find out the settlement of embankment soil, it will be supported by finite difference program. Results of studies on general is to find the effectiveness of embankment using prefabricated vertical drain (PVD) and without prefabricated vertical drain (PVD).AbstrakPenyelidikan terhadap tanah penting untuk dilakukan pada perencanaan konstruksi bangunan seperti pondasi, timbunan, jalan, dll. Untuk mengetahui daya dukung dan parameter-parameter tanah tempat akan dibangunnya sebuah bangunan Penyelidikan tanah dapat dilakukan dengan berbagai macam cara salah satunya adalah menggunakan uji sondir elektrik dengan tekanan air pori. Pada proyek timbunan memerlukan perhitungan pada tanahnya agar dapat diketahui besarnya penurunan pada tanah dan lama waktu tanah mencapai keadaan hidrostatis. Sehingga dilakukan uji sondir secara elektrik dan dari hasil uji sondir menghasilkan data berupa tahanan konus (qc), gesekan selimut (fs) dan pore pressure (u) yang akan diolah kedalam program CPET-IT agar menghasilkan parameter-parameter tanah yang akan digunakan untuk analisis penurunan pada tanah.Untuk mengetahui besarnya penurunan pada tanah timbunan maka akan dibantu program berbasis elemen higga. Hasil studi secara umum menunjukkan seberapa besar efektivitas pada timbunan dengan menggunakan prefabricated vertical drain (PVD) dan tanpa prefabricated vertical drain (PVD).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
