An unresolved problem in seismology concerns the occurrence of unexpectedly strong earthquakes within intraplate slow deforming regions. This paradox (strong magnitude, small deformation) has been the subject of numbers of studies in areas such as the Eastern United States and Canada (Talwani 1988, Assameur et Mareschal, 1995, Pollitz et al.,...

Si la production d'énergie renouvelable solaire, éolienne et géothermique est bien développée en Guadeloupe, il n'en est pas de même de l'éducation au développement durable dont la mise en place est très récente. Issu de travaux portant sur les mécanismes de contextualisation des savoirs scientifiques, l'enquête exposée ici vise à caractériser...

Comparing nearby areas with contrasted seismicity distributions like the French Variscan Armorican Massif (AM) and the surrounding intracratonic Paris Basin (PB) can help deciphering which parameters control the occurrence or absence of diffuse, intraplate seismicity. In this paper, we examine how lithosphere temperature, fluid pressure, and...

The 20th Caribbean Academy of Sciences Biennal Meeting was held in Guadeloupe, FWI, on November 24 th to 26 th, 2016. It has gathered over 130 participants from more than 14 countries within or outside the Caribbean. In this booklet, you may find all abstracts form the scientific sessions, and the desciption of two round tables and three...

GPS data collected in the Dominican Republic from 1994 to 2001 show that oblique convergence between the North American and Caribbean plates is partitioned between 5.2 ± 2 mm.yr−1 of dip‐slip reverse motion on the North Hispaniola thrust (approximately N‐S), and 12.8 ± 2.5 mm.yr−1 and 9.0 ± 9.0 mm.yr−1 of approximately E‐W left‐lateral...

In this paper, we provide the first structural map of Les Saintes archipelago (Guadeloupe, Lesser Antilles). The finite strain pattern displays four families of fault systems characterized by their statistical structural orientations: N000-N020, N050-N070, N090-N110 and N130-N140 trending fault systems. Our onshore results thus underline a...

After the January 12, 2010, Haiti earthquake, we deployed a mainly offshore temporary network of seismologic stations around the damaged area. The distribution of the recorded aftershocks, together with morphotectonic observations and mainshock analysis, allow us to constrain a complex fault pattern in the area. Almost all of the aftershocks...

The Karukéra spur is an easternmost submerged rise of the Lesser Antilles fore-arc in the Guadeloupe archipelago, culminating about 4000 m above the fore-arc basin 150 km west of the deformation front. The analysis of 3500 km 2D high-resolution multichannel seismic reflection and multibeam bathymetric data, and the study of 14 core samples,...
