Abstract Earthquake early warning systems are very important in mitigating more severe damage from earthquake events. Therefore, the analysis of signals is essential to obtain precise and accurate timing stations Indonesia. In this work, we have systematically investigated time arrival P-wave signal accelerometer West Java region, which measured 2009 2023 with magnitudes varied M 4.0-to 7.3. We carefully filtered raw data by using a Butterworth highpass filter cut-off frequency 0.075 Hz...
Sharia cooperatives in Islamic boarding schools are a form of economic business based on sharia principles which aims to economically empower and the surrounding community. It is hoped that this cooperative concept can create financial independence for provide fair transparent benefits their members. adopt every transaction, such as avoiding usury, gharar (obscurity), maysir (speculation), well using profit sharing system (mudharabah) interest-free loans. Its establishment help reduce...
An earthquake with a magnitude of M4.8 struck Sumedang, West Java, on December 31, 2023, at shallow depth 5 km. This study analyzes strong ground motion data from five nearby accelerograph stations (CSJM, TSJM, TOJI, ACBM, BALE) to evaluate the patterns Fourier amplitude spectra, spectral response acceleration (PSA), and their implications for building periods. The results reveal significant relationship between station's distance epicenter, local geological characteristics, earthquake's...
Palu City is an active seismic area in Indonesia due to the very Palu-Koro fault system.The development of city area, therefore, must consider risks induced by activities.The risk assessment has be supported information on subsurface characteristics.The aim this study investigate characteristics considering value V s30 (top 30 m shear-wave velocity).This parameter been related estimation site's ground shaking during occurrence earthquake.The measurements taken deep soil sediment include...
Yogyakarta merupakan salah satu wilayah yang aktif gempabumi di Indonesia. Sumber dapat berasal dari patahan lokal Opak bagian timur ataupun zona subduksi pada selatan Yogyakarta. Pembuatan peta mikrozonasi gempa sangat dibutuhkan untuk pertimbangan pembangunan infrastruktur atau bangunan tahan terhadap gempabumi. Upaya tersebut diharapkan mengurangi dampak resiko mungkin ditimbulkan. Pada pertengahan tahun 2014 telah dilakukan pengukuran kecepatan gelombang geser (Vs30) khususnya Kabupaten...
Abstract There were two fairly destructive earthquake phenomena in 2018 of M 6.4 and 7 at East Lombok District. However, severe damage occurred the West District, Mataram City, North District where three locations far from epicenter. This proves that potential for infrastructure does not only depend on magnitude source distance, but rather presence local site effects. study aims to determine dynamic characteristics soil distribution Peak Surface Acceleration (PSA). The method used are HVSR...
Abstrak Penelitian ini dilatarbelakangi oleh maraknya peristiwa gempa bumi di Indonesia beberapa tahun belakangan. Sementara itu, praktik umum dalam penentuan parameter tanah dan kegempaan masih banyak bergantung pada berbagai studi empiris. Maka dari penelitian bertujuan untuk mempelajari lewat fenomena amplifikasi gerak dengan kasus yang berlokasi Universitas (Depok). Metode digunakan meliputi: analisis data hasil pencatatan Hutan UI kedalaman 300 meter, pemodelan satu dimensi perangkat...
A 7.4 magnitude earthquake have strucked Donggala on September 28th 2018, followed by tsunami and liquefaction which hit Palu, Central Sulawesi, a few minutes later. This event had resulted in damage to buildings, caused more than 2,000 people were killed injured. Indonesia already building code form of SNI 1726:2002 been updated 1726:2012. paper analyses the hazard level 2018 compared existing design spectra, as mentioned simple analysis was carried out comparing earthquake’s acceleration...
Abstract Tectonic regimes in Indonesia caused the potential occurrence of earthquake with variated impact Indonesia. It could be a threat to people, infrastructure, and economic aspects All source types such as subduction zones are big-one event that has been considered anticipate part mitigation implementation for reducing victims. Almost all regions have probability destructive region by earthquakes. One cluster is related Java Island Sunda strait. The early warning system (EEWS) goal...
Estimating magnitude completeness (Mc) value and its uncertainty of earthquake catalog within 1,000 km West Kalimantan Nuclear Power Plant (NPP) potential site has been performed. Three catalog-based methods were used to acquire Mc value, namely Maximum Curvature (MAXC), Goodness-of-Fit Test (GFT), by b-value Stability (MBS) methods. Considering the Mc, we utilized Monte Carlo bootstrap approach using 3,000 samples. MAXC was found have lowest 4.7Mw±0.02 for entire year range. Temporal...
Abstract The Government of Indonesia has committed to deploying a network 500 strong-motion sensors throughout the nation. data from these have potential provide critical near-real-time information on level ground shaking and impact Indonesian earthquakes near communities. We describe implementation real-time ‘ShakeMaps’ within Indonesia's Agency Meteorology, Climatology Geophysics (BMKG). These ShakeMaps are intended underpin earthquake situational awareness tools. use new is demonstrated...
Lombok Island and its surrounding is an area that has a high seismicitys level because it located in the Eastern Sunda Arc. Tectonically, between Indo-Australia plate collision zone with Eurasia south fult of backarc Bali-Flores north. This research’s purposed to determine distribution vulnerability index peak ground acceleration value are used GSS value, so mapping potential damage areas could be done. The microtremor data taken on 32 observation points distributed Island. Microtremor...
The Pasaman earthquake which occurred on 25 February 2022, with a magnitude of 6.2, caused casualties and infrastructure damage. Vulnerability identification determines the potential extent to system or unit tends be damaged. in this study was carried out based four vulnerability indicators, namely: rate soil movement from satellite image processing, type classification Vs30, corrected isoseismal shakemap, residential area maps. Each indicator, their respective weightage, is then scored...
