Résumé : International audience
Sandbox experiments, using a two-dimensional and a three-dimensional approach, are used to study the deformation of margins in response to seamount subduction. Successive mechanisms of deformation are activated during the subduction of conical seamounts. First, reactivation of the frontal thrusts and compaction of the accretionary wedge is observed. Then, back thrusting and, conjugate strike-slip faulting develops above the leading slope of the subducted seamount. The basal d6collement is deflected upward in the wake of the subducting high, and a large shadow zone develops behind the seamount trailing slope. Consequently, frontal accretion is inhibited and part of the frontal margin is dragged into the subduction zone. When the main d6collement returns to its basal level in the wake of the seamount, the margin records a rapid subsidence and a new accretionary wedge develops, closing the margin reentrant. The sediments underthrusted in the wake of the seamount into the shadow zone, are underplated beneath the rear part of the accretionary wedge. Substantial shortening and thickening of the deformable seaward termination of the upper plate basement, associated with basal erosion is observed. Seamount subduction induces significant material transfer within the accretionary wedge, favors large tectonic erosion of the frontal margin and thickening of the rear part of the margin. The subduction and underplating of relatively undeformed, water-ladden sediments, associated with fluid expulsion along the fractures affecting the margin could modify the fluid pressure along the basal ddcollement. Consequently, significant variations of the effective basal friction and local mechanical coupling between the two plates could be expected around the subducting seamount.

Résumé : International audience
At the North-Ecuadorian convergent margin (1°S–1.5°N), the subduction of the rough Nazca oceanic plate leads to tectonic erosion of the upper plate and complex seismogenic behavior of the megathrust. We used three selected pre-stack depth migrated, multi-channel seismic reflection lines collected during the SISTEUR cruise to investigate the margin structure and decipher the impact of the subducted Atacames seamounts on tectonic erosion, interseismic coupling, and seismogenesis in the region of the 1942 Mw7.8 earthquake.This dataset highlights a subducted ∼30×40 km∼30×40 km, double-peak seamount that belongs to the Atacames seamount chain and that is associated with a deep morphologic re-entrant containing mass transport deposits.The seamount subduction uplifted the margin basement by ∼1.6 km and pervasively broke the margin by deep and intense reverse faulting ahead of the seamount, a process that is likely to weaken considerably the margin. In the seamount wake, the basement reverse fault system rotated counter-clockwise. This faulted basement is overlain with slope sediment sliding along listric normal faults that sole out onto the BSR. This superposition of deep tectonic contraction within the basement and shallow gravitational extension deformation within the sediment highlights the key role of gas hydrate on outer slope erosion.In addition to long-term regional basal erosion, the margin basement has thinned locally by an extra 0.8–1 km in response to the subduction of the Atacames seamount chain and hydrofracturing by overpressured fluids at the margin toe. This pervasively and deeply fractured margin segment is associated with a seismically quiet and GPS-modeled low interseismic coupling corridor that terminates downdip near the 1942 epicenter and locked zone. We suggest that the deeply buried double-peak Atacames seamount triggered the 1942 earthquake ahead of its leading flank. This result supports previous studies proposing that subducted seamounts provide unfavorable conditions for locking the updip segment of the plate boundary limiting the updip extent of seismogenic zones, but may favor large subduction earthquakes at greater depths.

Résumé : At its seasonal peak the Amazon/Orinoco plume covers a region of 10^6 km2 in the western tropical Atlantic with more than 1m of extra freshwater, creating a near-surface barrier layer (BL) that inhibits mixing and warms the sea surface temperature (SST) to >29oC. Here new sea surface salinity (SSS) observations from the Aquarius/SACD and SMOS satellites help elucidate the ocean response to hurricane Katia, which crossed the plume in early fall, 2011. Its passage left a 1.5psu high haline wake covering >10^5 km2 (in its impact on density, the equivalent of a 3.5oC cooling) due to mixing of the shallow BL. Destruction of this BL apparently decreased SST cooling in the plume, and thus preserved higher SST and evaporation than outside. Combined with SST, the new satellite SSS data provide a new and better tool to monitor the plume extent and quantify tropical cyclone upper ocean responses with important implications for forecasting.

Résumé : An analysis is presented for the spatial and intensity distributions of North Atlantic extreme atmospheric events crossing the buoyant Amazon-Orinoco freshwater plume. The sea surface cooling amplitude in the wake of an ensemble of storm tracks traveling in that region is estimated from satellite products for the period 1998-2012. For the most intense storms, cooling is systematically reduced by approximate to 50% over the plume area compared to surroundings open-ocean waters. Historical salinity and temperature observations from in situ profiles indicate that salt-driven vertical stratification, enhanced oceanic heat content, and barrier-layer presence within the plume waters are likely key oceanic factors to explain these results. Satellite SMOS surface salinity data combined with in situ observations are further used to detail the oceanic response to category 4 hurricane Igor in 2010. Argo and satellite measurements confirm the haline stratification impact on the cooling inhibition as the hurricane crossed the river plume. Over this region, the SSS mapping capability is further tested and demonstrated to monitor the horizontal distribution of the vertical stratification parameter. SMOS SSS data can thus be used to consistently anticipate the cooling inhibition in the wake of TCs traveling over the Amazon-Orinoco plume region.

Résumé : International audience
Despite convergent margins being unstable systems, most reports of huge submarine slope failure have come from oceanic volcanoes and passive margins. Swath bathymetry and seismic profiles of the northern Hikurangi subduction system, New Zealand, show a tapering 65-30 km wide by 65 km deep margin indentation, with a giant, 3150+_630 km 3, blocky, debris avalanche deposit projecting 40 km out across horizontal trench fill, and a debris flow deposit projecting over 100 km. Slide blocks are well-bedded, up to 18 km across and 1.2 km high, the largest being at the avalanche deposit's leading edge. Samples dredged from them are mainly Miocene shelf calc-mudstones similar to those outcropping around the indentation. Cores from cover beds suggest that failure occurred-170 +_40 ka, possibly synchronously with a major extension collapse in the upper indentation. However, the northern part of the indentation is much older. The steep, straight northern wall is close to the direction of plate convergence and probably formed around 2.0-0.16 Ma as a large seamount subducted, leaving in its wake a deep groove obliquely across the margin and an unstable triangle of fractured rock in the 60 ø angle between groove and oversteepened margin front. The triangle collapsed as a blocky avalanche, leaving a scalloped southern wall and probably causing a large tsunami. Tentative calculations of compacted volumes suggest that the indentation is over 600 km 3 larger than the avalanche, supporting a two-stage origin that includes subduction erosion. Since failure, convergence has carried the deposits-9 km back toward the margin, causing internal compression. The eventual subduction/accretion of the Ruatoria avalanche explains the scarcity of such features on active margins and perhaps the nature of olistostromes in fold belts.

Résumé : A partir de 1996 pour combattre une inflation galopante, Haïti a mis en place une politique de ciblage de la masse monétaire avec un objectif d’inflation. La forte inflation a pris naissance dans l’accumulation du déficit budgétaire et le financement monétaire de celui-ci par le seigneuriage. Cette pratique du financement par l’impôt inflationniste engendre donc un problème de crédibilité, en dépit de la double circulation monétaire caractérisée par un niveau élevé de dollarisation de l’économie qui a atteint 50% dès 2004. La politique monétaire mise en œuvre vise à éviter le biais inflationniste et différentes approches pour améliorer la crédibilité ont été considérées. La crise économique commencée en 2007 dans les pays développés, est née de l’instabilité des marchés financiers et a obligé la mise en place de politique monétaire non conventionnelle afin d’éviter la trappe de liquidité. Cette crise a donné lieu à une accumulation de réserves internationales et un faible taux d’intérêt dans les économies des pays émergents et les économies des pays sous-développés. Il devenait évident que le fondement théorique de la stratégie de politique monétaire demeure la recherche à la fois de la stabilité monétaire et la stabilité des marchés financiers afin de conserver la crédibilité et l’efficacité de la politique monétaire des banques centrales. L’utilisation abusive faite par la FED aux USA de l’assouplissement quantitatif, fait craindre une crise de la dette souveraine des Etats, la création de bulle spéculative, et un retour à la récession. Avec le cas d’Haïti, les anticipations ne sont pas rationnelles à cause des erreurs de prévisions. Une analyse jointe des taux des banques, en utilisant un modèle VECM, ne nous a pas permis de trouver un taux d’équilibre de long terme entre eux. Le test de Seo conclu que les chocs ont affecté la dynamique de ces taux. Les accords avec le FMI ont permis une très faible amélioration de l’efficacité de la politique monétaire avec l’accumulation de réserves dans la foulée de la crise qui a démarré en 2007.
Since 1996 in order to fight inflation, Haiti put in place a monetary policy targeting money supply with inflation target. Inflation high gets started from budget deficit accumulation and monetary financing by seigniorage. This practice of financing by inflationary taxes implies a problem of credibility of monetary policy even with a double monetary circulation and a dollarization of the economy reaching 50% since 2004. The monetary policy implementation aims to avoid inflation bias and different approaches for improving credibility has been considered. The economic crisis started in 2007 created by the instability of the financial markets, forced the establishment of non-conventional monetary policy to avoid the liquidity trap. This crisis has resulted in an accumulation of international reserves and low interest rate in emerging economies and the economies of underdeveloped countries. It became more and more evident that the theoretical basis of the monetary policy strategy remains looking for both, monetary stability and the stability of the financial markets, in order to maintain the credibility and efficiency of the monetary policy of central banks. The misuse made by the FED in the USA of quantitative easing, rise concerns about a crisis of sovereign debt of the Sates, the creation of speculative bubble, and a possible return to the recession. With the case of Haiti, the expectations are not rationales because of forecast errors. A joint analysis of banks interests’ rates using a VECM model has not enabled us to find a long run equilibrium rate between them. The Seo test concluded that chocks affect the dynamic of both rates. The agreements with the IMF allowed improving weakly the monetary policy efficiency with the accumulation of international reserves in the wake of the crisis which started in 2007.
