Seismic performance of moment frames under multiple fling-step pulse ground motions

open access: yesJurnal Ilmiah SINERGI, 2022
The displacement fling-step pulse seldom signatures near-field earthquake in its ground motions. It is well recognized that the near-field ground motion with velocity pulse amplifies the building drift larger than the regular ground motion.

Q fever outbreak in the terraced vineyards of Lavaux, Switzerland

open access: yesNew Microbes and New Infections, EarlyView., 2014
Abstract Coxiella burnetii infection (Q fever) is a widespread zoonosis with low endemicity in Switzerland, therefore no mandatory public report was required. A cluster of initially ten human cases of acute Q fever infections characterized by prolonged fever, asthenia and mild hepatitis occurred in 2012 in the terraced vineyard of Lavaux ...

Simulation of strong ground motions [PDF]

open access: yesBulletin of the Seismological Society of America, 1980
abstractThe estimation of potential strong ground motions at short epicentral distances (Δ = 10 to 25 km) resulting from large earthquakes, M ≧ 6.5, generally requires extrapolation of a limited data set. The goal of this project has been to quantify the extrapolation through a simulation technique that relies heavily upon the more extensive data set ...

Impulsive Signals Produced by Earthquakes in Italy and Their Potential Relation with Site Effects and Structural Damage

open access: yesGeosciences, 2021
Near fault seismic records may contain impulsive motions in velocity-time history. The seismic records can be identified as impulsive and non-impulsive depending on the features that their waveforms have.

Church bells and ground motions [PDF]

open access: yesJournal of Seismology, 2020
Although the primary objective of seismic stations is the recording of waves generated by natural seismicity, the sensors can detect vibrations generated by different sources of natural and anthropogenic origin. The interest in identifying these sources has increased in the last years with the use of background seismic vibrations to obtain images of ...

Site specific design response spectrum proposed for the capital city of Agartala, Tripura

open access: yesGeomatics, Natural Hazards & Risk, 2016
The design response spectrum is smooth in shape compared to other response spectra. The objective of design spectra is to estimate the possible earthquake lateral loads which may experience on a particular structure during its design life. In this study,
