How wide is the seismogenic zone of the Lesser Antilles forearc?

Gutscher, Marc-André Westbrook, Graham K. Marcaillou, Boris

The Lesser Antilles subduction zone has produced no recent strong thrust earthquakes, making it difficult to quantify the seismic hazard from such events. The Lesser Antilles arc has a low subduction rate and an accretionary wedge that is very wide at its southern end. To investigate the effect of the wedge on seismogenesis, numerical models of...

Thermally-constrained fluid circulation and seismicity in the Lesser Antilles subduction zone

Ezenwaka, Kingsley Marcaillou, Boris Laigle, Mireille

At subduction zones, fluid circulation and elevated pore pressure are key factors controlling the seismogenic behavior along the plate interface by reducing absolute fault strength, increasing the time return of high magnitude co-seismic rupture and favoring aseismic slip. The Lesser Antilles is an endmember subduction zone where the slow...
