This paper presents the experimental study of liquefaction potential for sandy soil in Prambanan Area, Yogyakarta, Indonesia, which underwent due to Mw 6.3 Jogja Earthquake on May 27, 2006. Shaking table tests considering variation acceleration and shaking duration were performed investigate sand. The time stages including start liquefaction, pore pressure dissipation, observed. percentage incr...

Silt liquefaction can occur due to the rapid cyclic loading of sediments. This result in loss bearing capacity underlying sediments and damage foundations infrastructure. Therefore, assessing hazards is an important aspect disaster prevention risk assessment geologically unstable areas. The purpose this study assess silt by using horizontal-to-vertical spectral ratio method. Single-station nois...

The results of research on some aspects of coastal dynamics during earthquakes, carried out in the Institute of Hydro-Engineering, are summarized. The attention is focused on the liquefaction-related phenomena, like modeling the earthquake-induced generation of pore-pressures and subsequent liquefaction of subsoil, the behavior of liquefied soil, underwater landslides, sinking of structures in ...

iran is an active seismic region. earthquake damage is commonly controlled by three interacting factors including source and path characteristics, local geological and geotechnical conditions and type of the structures. obviously, all of this would require analysis and presentation of a large amount of geological, seismological and geotechnical data. in this paper, nonlinear geotechnical seismi...

The study area is located in one of the most earthquake prone regions southern Ethiopia, which characterized by small-to-intermediate occurrences causing damage to buildings. Predicting liquefaction hazard potential and local site effects are imperative manage reduce buildings loss lives. objectives this work were perform equivalent linear response analysis (ELA) shear wave velocity (Vs.)-based...

Bachmann et al. (2005) contend that a major fraction of flocculent sediments, a ‘‘fluid mud layer,’’ which has accumulated in Lake Apopka, Florida, since 1947, originated from sediment liquefaction of consolidated macrophyte-derived sediments. In addition, they contend that the underlying historic sediments are not only a major source of fluid mud, but also the source of organic matter for inte...

Abstract Mapping the susceptibility of earthquake-induced soil liquefaction at continental scale is a challenge. Susceptibility soils to tendency certain geomaterials undergo severe stiffness degradation and loss shear strength. The latter could be induced by cyclic loading seismic events. surface evidence local phenomenon, detailed geotechnical field investigations are not available for region...

Hydrothermal liquefaction of algae biomass is a promising technology for the production of sustainable biofuels, but the non-oil, aqueous co-product of the process has only been examined to a limited extent. The aqueous phase from liquefaction of the alga Nannochloropsis oculata (AqAl) was used to make growth media for model heterotrophic microorganisms Escherichia coli, Pseudomonas putida, and...
