Modelling strong seismic ground motion: three-dimensional loading path versus wavefield polarization [PDF]

, 2012
Seismic waves due to strong earthquakes propagating in surficial soil layers may both reduce soil stiffness and increase the energy dissipation into the soil.

Soil amplification in low-to-moderate seismic regions [PDF]

Bulletin of Earthquake Engineering, 2016
The results of a study that investigates potential revisions of the spectral shape factors used in standards in regions of low-to-moderate seismicity are presented here. Using an equivalent linear analysis, the investigation particularly focuses on the effects of seismic intensity associated with rare and very rare intraplate earthquake events on site ...

Mapping surface motion parameters and liquefaction susceptibility in Tribhuvan International Airport, Nepal

Geomatics, Natural Hazards & Risk, 2017
Local site effects and liquefaction are major causes of building and lifeline damage in Kathmandu Valley as depicted by several historical earthquakes including recent 2015 Gorkha earthquake (Mw 7.8). Critical facilities like airports play important role

An empirical method to estimate the effect of soil on the rate for transmission of damping‐off disease

, 2004
The ability of some soils to suppress soil-borne diseases has been long recognised, but the underlying epidemiological mechanisms by which this occurs are largely unknown.• Using damping-off disease caused by Rhizoctonia solani, spreading through ...

Surabaya earthquake hazard soil assessment [PDF]

E3S Web of Conferences, 2020
The vulnerability of land in an area to earthquake ground motions is one of the factors causing damage caused by the earthquakes. The city of Surabaya, which is crossed by two active fault segments, needs an assessment to reduce the risk of being ...

Determination of Soil Properties by Using Multi-Channel Analysis Method Records of Microtremor, Earthquake and Surface Waves: A Sample Implementation from AFAD Campus

Doğal Afetler ve Çevre Dergisi, 2021
The most valid way to determine the soil amplification is to use the analysis of strong ground motion records. The Earthquake Observation Station located in Ankara AFAD campus was established in 2014.
