Shallow ambient-noise 3D tomography in the concepción basin, Chile: Implications for low-frequency ground motions
(Seismological Society of America, 2019)
Forecasting surface seismic intensities is the main objective of much of the research in seismic engineering. The seismic demand for tall buildings, bridges, wind farms, and other existing slender structures is predominantly ...
Time and Space Variation of Strong Motions Parameters for Subduction Interface Earthquakes
(2017)
The strong ground motions generated by earthquakes can be related to the characteristics of the earthquakes source (stress drop, rupture velocity etc..), and therefore to the frictional conditions of the faults. These ...
Sensitivity of synthetic seismograms for different seismic scenarios in north Chile
(National Information Centre of Earthquake Engineering, 2017)
This research studies the sensitivity of spectral response values to various physical earthquake scenario parameters, the latter used to generate synthetic low frequency seismograms in North Chile. Ten earthquake scenarios ...
Strong motion simulation of the M8.0 August 15, 2007, Pisco earthquake; effect of a multi-frequency rupture process
(Journal of Disaster Research, 2013-03)
We investigated the broadband frequency (0.05-30 Hz) radiation characteristics of the August 15, 2007, Mw8.0 Pisco, Peru, earthquake by simulating the near-source strong ground motion recordings in Parcona city (PCN) and ...
Seismic risk of sliding ground-mounted rigid equipment
(2020)
This study discusses a general formulation for risk assessment of ground-mounted rigid sliding equipment and contents during earthquakes. The displacement and acceleration response of blocks during earthquakes and risk ...
Rupture parameter sensitivity of low frequency ground motion response spectra using synthetic scenarios in North Chile
(SPRINGER, 2021)
This research performs a sensitivity analysis of response spectrum values for various physical earthquake parameters, which are used to generate synthetic seismograms consistent with the expected seismicity in north Chile. ...
Synthetic Hybrid Broadband Seismograms Based on InSAR Coseismic Displacements
(2014)
Conventional acceleration records do not properly account for the observed coseismic ground displacements, thus leading to an inaccurate definition of the seismic demand needed for the design of flexible (long period) ...
The influence of the complexity of ground surface in the flow through a spectral analysis of turbulent quantities in the stable boundary layerA influência da complexidade da superfície terrestre no fluxo através de uma análise espectral de quantidades turbulentas na camada de limite estável
(Universidade Federal de Santa Maria, 2018)
Scenario source models and strong ground motion for future mega-earthquakes: application to Lima, Central Peru
(Seismological Society of America, 2015-01)
The 2011 moment magnitude (Mw) 9.0 Tohoku-Oki Japan earthquake occurred in a region where giant megathrust earthquakes were not expected. This earthquake proved the difficulty in assessing seismic hazard by relying mainly ...
