Yeryüzünde bir sahada oluşan deprem yer hareketi, fayın kırılma mekanizmasına, sismik kabuğun yapısına ve yüzeye yakın zeminler ile yumuşak kayaçların özelliklerine bağlıdır. Yüzeye zeminlerin sedimanter kaynağından uzak mesafelerde bile önemli ölçüde yapı hasarlarına yol açabildikleri bilinmektedir. Ülkemizde son dönemlerde yaşanan depremlerde de bu durum gözlenmiştir. 30 Ekim 2020 tarihinde E...

the investigation of this paper focuses on eastern part of shahroud fault system in middle-east alborz. this fault system is an important part in the seismotectonic map of the area. we used two local temporary dense seismological networks data installed around the fault system for several months during 2007 and 2008 and simultaneously micro-earthquakes data recorded by the permanent seismologic...

following the 1994 northridge and 1995 kobe earthquakes, most of modern structures damaged seriously or devastated totally despite the seismic codes of these countries that had been expected to bear advanced criteria for seismic design of structures. after extensive research, the most probable reason of those destructions was attributed to special specifications of near-field earthquakes. in th...

The state-of-the-art of near-fault problems in earthquake engineering is comprehensive reviewed. Strong ground motions in the near-fault region exhibit several new characteristics, which cause the attentions of both seismologists and engineers who zealously studied these ground motions during the last two deceases. The investigation on ground motions can interpret the mechanism of the earthquak...

We present various techniques to visualize timevarying, 3D earthquake modeling datasets. We use RIVA (Remote Interactive Visualization and Analysis) to visualize the surface deformation as a synthetic interferogram overlaid on top of a high resolution LandSAT image and digital terrain. We use ParVox (PARallel VOXel Renderer) to visualize the simulated normal stress and shear stress along the No...

 Abstract—According to the design procedure of fault selfdiagnosis system and features of automatic transmission system, the list of relation and mapping between fault symptoms and fault causes are made in this paper. Applying the approach of fault self-diagnosis based on fuzzy neural network, fault diagnosis of the automatic transmission electronic control system is realized. The structure of...

We perform 2-D simulations of earthquakes on rough faults in media with random heterogeneities (with von Karman distribution) to study the effects of geometric and material heterogeneity on the rupture process and resulting high-frequency ground motions in the near-fault region (out to ∼20 km). Variations in slip and rupture velocity can arise from material heterogeneity alone but are dominantl...

The near-source energy released on a fault is estimated through the strain energy change and the fracture energy from the results of kinematic waveform inversion and dynamic modeling for two different types of earthquakes: a shallow crustal earthquake, the 2000 Tottori, Japan (Mw 6.6) earthquake, and an in-slab event, the 1999 Oaxaca, Mexico (Mw 7.5) earthquake. The procedure incorporates the s...
