in this paper, the behaviour of buried pipelines under the effect of propagation of seismic waves and faulting is studied seperately. the stability of this type of structure was first studied by using three different methods proposed by newmark-hall, kenndey et al. and wang - yeh under the effect of ground faulting. by parametric study, the effect of soil types, size of pipeline, depth of embed...

The global effort to understand the molecular drivers of cancer onset and progression is now coming to fruition with the identification of specific genomic and epigenomic events that influence signaling through key oncogenic pathways. Genetic studies using inducible expression of the critical growth controlling oncogenes MYC, RAS, PI3K and AKT have shown unequivocally that, in conjunction with ...

Fracture-pore complexes, located at fault zones of Darriwilian carbonates, are the main exploration targets in Shunbei area, Tarim Basin. This article focuses on carbonate characteristics Lower Ordovician Well ShunbeiPeng1 (SHBP1), is sandwiched by two trending NW-SE deep-seated, strike-slip faults Shuntuoguole uplift. Based detailed core investigation and careful petrographic examination, rese...

We investigated the source characteristics of large earthquakes which occurred in the Michoacan, Mexico, seismic gap during the period from 1981 to 1986 in relation to historical seismicity in the region. The rupture pattern of the Michoacan gap during this period can be characterized by a sequential failure of five distinct asperities. Before 1981, the Michoacan gap had not experienced a large...

For one week during September 2007, we deployed a temporary network of field recorders and accelerometers at four sites within two deep, seismically active mines. The ground-motion data, recorded at 200 samples/sec, are well suited to determining source and ground-motion parameters for the mining-induced earthquakes within and adjacent to our network. Four earthquakes with magnitudes close to 2...

[1] The volcanic eruption on Miyakejima, Japan, in 2000 was marked by the largest earthquake swarm ever recorded in Japan, a seismicity migration accompanying a dike intrusion as the dike propagated from Miyakejima to the northwest, and formation of a caldera on Mount Oyama on Miyakejima. In this study, we propose a seismic source model which can be used to model both seismic and geodetic displ...

The design and behavior of a ductile structural system called a knee-braced moment frame are presented in this paper. The design of this structural system is based on a capacity-design concept that results in ductile behavior. The knee part is a fuse-like component that dissipates energy by the formation of plastic flexural and/or shear hinges at its ends and mid-span, when the building is subj...

Studies of the power-law relations of seismicity and earthquake source parameters based on the one-dimensional (1-D) Burridge-Knopoff’s (BK) dynamical lattice model, especially those studies conducted by Taiwan’s scientists, are reviewed in this article. In general, velocityand/or state-dependent friction is considered to control faulting. A uniform distribution of breaking strengths (i.e., the...
