Abstract We explore the thesis that resonances in trees result forests acting as locally resonant metamaterials for Rayleigh surface waves geophysics context. A geophysical experiment demonstrates a wave, propagating soft sedimentary soil at frequencies lower than 150 Hz, experiences strong attenuation, when interacting with forest, over two separate large frequency bands. This is interpreted using finite element simulations demonstrate observed attenuation due to bandgaps are arranged...

Recent destructive earthquakes have confirmed the importance of hazard and vulnerability studies to predict prevent impact large seisms. Most seismic risk analysis considers buildings as a passive constituent integrated into analysis. This approach neglects possible contribution building vibration free field. article describes an site-city effects, that is, interaction city with soft soil layers.

In countries with a moderate seismic hazard, the classical methods developed for strong motion prone to estimate behaviour and subsequent vulnerability of existing buildings are often inadequate not financially realistic. The main goals this paper show how modal analysis can contribute understanding building response good relevancy model based on ambient vibrations estimating structural deformation under earthquakes. We describe application an enhanced technique (Frequency Domain...
We investigate recordings from weak to moderate earthquakes, with magnitudes ranging between about 3 and 5, recorded by the French Accelerometric Network. S-wave spectra are modelled as a product of source, propagation site terms. Inverting large data sets multiple earthquakes at stations allows us separate three contributions. Source parameters such moment magnitude, corner frequency stress drop estimated for each earthquake. provide first complete homogeneous catalogue France, events...

Ground-motion prediction equations (GMPE) are essential in probabilistic seismic hazard studies for estimating the ground motions generated by sources. In low seismicity regions, only weak available lifetime of accelerometric networks, and selected usually models established from foreign data. Although most ground-motion have been developed magnitudes 5 above, minimum magnitude often used regions is smaller. Desaggregations shown that, at return periods engineering interest, lower than can...
A potentially unstable limestone column (∼1000 m3, Vercors, French Alps) delineated by an open rear fracture was continuously instrumented with two three-component seismic sensors from mid-May 2009 to mid-October 2011. Spectral analysis of noise allowed several resonance frequencies be determined, ranging 6 21 Hz. The frequency domain decomposition (FDD) technique applied the ambient vibrations recorded on top rock column. Three vibration modes were identified at 6, 7.5 and 9 Hz, describing...

The characterization and monitoring of buildings is an issue that has attracted the interest many sectors over last two decades.With increasing use permanent, continuous real-time networks, ambient vibrations can provide a simple tool for identification dynamic building parameters.This study focused on long-term variation frequency damping in several buildings, using Random Decrement Technique (RDT).RDT provides fast, robust accurate analysis improves reliability measurements structural...
ABSTRACT Generalized inversion techniques (GITs) have become popular for determining seismological parameters (e.g., source, attenuation, and site response), particularly in low-to-moderate seismicity regions. Indeed, GITs can potentially provide reliable site-response estimates when a minimum number of recordings is available, as well valuable information about source regional attenuation characteristics. Significant advances been made on which different approaches hypotheses were...
Understanding rupture mechanisms, seismicity propagation, distribution, and migration after a major earthquake relies on the quality of catalogs, particularly their detection capabilities, location accuracy, magnitude completeness. On February 27, 2010, Mw 8.8 struck Maule region in south-central Chile, causing widespread damage substantial loss life. As largest well-instrumentally recorded this event offers unique opportunity to revisit an old dataset, refine aftershock sequence analysis,...

Seismic wave characteristics are influenced by several physical processes, including theearthquake source, geometrical effects such as topography, and local amplification phenomena.In urban environments, civil structures introduce an additional complexity in the wavefieldevolution. While earthquake engineers have traditionally regarded buildings passiverecipients of seismic waves, diverse seismological studies demonstrated that buildingclusters can significantly alter ground motion (e.g....
