Les données GPS acquises dans le rift de Corinthe pendant onze campagnes menées entre 1990 et 2001 fournissent les vitesses de 57 points avec une précision de ~1.5mm/an. Le Péloponnèse se déplace avec une vitesse de 30 mm/an en direction N215°E par rapport à l'Europe stable. L'extension à travers le rift est accommodée dans une bande étroite, à l'intérieur du golfe, en mer. Son taux d'ouverture augmente d'est en ouest et est de 16 mm/an près de la ville d'Aigion. Les deux côtés du golfe se comportent comme des blocs rigides affectés par une ratation horaire présentant des taux de 7+-0.5°/Ma et 2.8+-0.8°/Ma respectivement pour le bloc nord et le bloc sud. Les taux d'accumilation de la déformation sur les failles majeures localisées le long de la côte sud du Golfe de Corinthe sont inférieurs à mm/an. Cela implique des périodes de récurrence longs pour des forts tremblements de terre sur ces failles. Aux extrémités occidentale et orientale du rift la déformation est plus distribuée. Le champ de vitesse obtenu nous a permis de contraindre la comparaison entre les nouvelles et les anciennes coordonnées de 224 anciens piliers appartenant au vieux réseau grec de triangulation. L'analyse des mouvements cosismiques et inter-sismiques verticaux a été conduites sur une importante base d'interférogrammes. La présence de artefacts atmosphériques dans les interférogrammes représente la limite principale pour la détection des déformations du terrain. L'approche méthodologique menée popur réduire les contributions troposphériques globale et locale dans les interférogrammes a besoin de la connaissance détaillée des réflecteurs permanents (RP), ce qui peut être obtenues uniquement à travers l'analyse d'une grande population d'interférogrammes. La correction de l'effet atmosphérique global exploite la corrélation entre la phase des RP et leur élévation, et la correction des artefacts locaux est basée sur la corrélation entre interférogrammes contenant la même image
Comportement transitoire et rôle des barrières dans la lacune sismique Nord Chili - Sud Pérou by Jorge Jara( )

The aim of this Ph.D. thesis is to have a better comprehension of the interactions between coupling, slow slip events (SSEs) and the seismic ruptures in subduction zones. This work focuses on the North Chile - South Peru subduction zone that has been recognized as a mature seismic gap. Thus, the region has been the target of an important international effort in geophysical instrumentation (GPS and seismological stations), since the mid-2000s. The region has been affected by several well-registered earthquakes, that makes it good case to study the earthquake preparation phase and the relationship between coupling, SSE and seismic rupture.The 65 stations available in the region have been processed in double differences using the GAMIT-GLOBK software in the period 2000-2014. The GPS displacement time series have been analyzed and the associated displacements to the different stages of the seismic cycle as well as seasonal signals have been modeled.The analysis of the tendencies in the GPS time-series evidences a change in the velocity field before and after the Tarapaca slab-pull earthquake occurrence in June 2005, in the range of latitude affected by Iquique earthquake in 2014. This velocity change is associated with a change in the shallow and deep seismicity rates. The analysis of the declustered catalog shows that the velocity change observed affects the background seismicity as well, that often seen as a proxy for the tectonic loading. Finally, we find interactions between shallow and deep seismicity, that may play an important role in the interface earthquakes preparation phase. At a shorter time scale, the time series show another change in velocity 8 months before Iquique earthquake. Models indicate that the velocity change corresponds to an SSE Mw 6.5, mainly aseismic, corresponding to the long preparation phase of the earthquake.The short-term GPS velocity variations have also been analyzed on residual signal. It allows identifying, thanks to a matched-filter, 48 small SSEs during the interseismic period. These events are localized mostly in the deeper part of the seismogenic zone, in areas where the coupling is low or with intermediate values. It suggests that the slip in these regions is produced in burst way. Some of those events are correlated with peaks of seismic activity, especially at intermediate depths.Finally, the kinematic rupture process of Iquique earthquake process and its biggest aftershock are studied, employing a combination of high-rate GPS and strong motion data. The static displacements are inverted to characterize the slip. This static solution is used as apriori information for a sequence of kinematic inversions in the frequency domain. The results show that both events have a bimodal slip distribution, segmented along dip. The lateral extension of the mainshock is centered on a forearc offshore basin associated with a gravity anomaly, and may be controlled by tectonic structures of the upper crust. The aftershock is located in an area with strong Coulomb Stress Changes induced by the mainshock, suggesting that it was triggered by the mainshock.Thanks to the combination of geodetic and seismological data, this thesis provides a detailed vision of the processes involved during the Iquique earthquake and the previous decades. The research prospects raised by this work are numerous, particularly on the possibilities of refined observations of the phenomena associated with the seismic cycle and the preparation of large subduction earthquakes

Abstract: Background: Second-line therapy has consistently demonstrated survival benefit if compared with best supportive care; however, there is limited evidence whether further lines of treatment may improve the prognosis of advanced gastric cancer (AGC) patients. Materials and Methods: Starting from a real-world cohort of 868 AGC patients, we retrospectively analyzed baseline parameters, tumor characteristics, and treatment data of those treated with at least three lines. Categorical features were described through cross-tables and chi-square test. We explored the impact of treatment intensity and progression-free survival (PFS) experienced in previous lines on PFS and overall survival in third-line by uni- and multivariate Cox regression models and described by Kaplan-Meier estimator plot with log-rank test. Results: Overall, 300 patients were included in the analysis. The most common site of primary tumor was gastric body; 45.3% of cancers had an intestinal histotype, 14% were human epidermal growth receptor 2 positive. In third-line, 45.7% of patients received a single-agent chemotherapy, 49.7% a combination regimen. Patients who had experienced a first-line PFS ≥6.9 months had a better prognosis compared with those who had achieved a shorter one. Consistently, a second-line PFS ≥3.5 months positively influenced the prognosis. Patients receiving a third-line combination regimen had better outcomes compared with those treated with a single-agent chemotherapy. Conclusion: Our real-world study confirms that selected AGC patients may receive third-line treatment. Longer PFS in previous lines or a more intense third-line treatment positively influenced prognosis. Further efforts are warranted to define the best therapeutic sequences, and to identify the optimal candidate for treatment beyond second-line. Implications for Practice: The benefit of third-line treatment to advanced gastric cancer patients is controversial. This study depicts a real scenario of the clinical practice in Italy, confirming that a non-negligible proportion of patients receive a third-line therapy. Longer progression-free survival in previous treatment lines or higher third-line treatment intensity positively influenced prognosis. Including a large number of real-world patients, this study provides information on third-line treatment from the daily clinical practice; moreover, its results help in defining the best therapeutic sequence and offer some hints to select the optimal candidate for treatment beyond second-line. Abstract : This article explores the characteristics of advanced gastric cancer patients receiving a third-line chemotherapy, as well as factors that could be useful in identifying those patients who might benefit from a further line of treatment
