  abstract = {{K}ick 'em {J}enny volcano is the only known active submarine volcano in the {L}esser {A}ntilles. {I}t lies within a horseshoe-shaped structure open to the west northwest, toward the deep {G}renada {B}asin. {A} detailed bathymetric survey of the basin slope at {K}ick 'em {J}enny and resulting high-resolution digital elevation model allowed the identification of a major submarine landslide deposit. {T}his deposit is thought to result from a single sector collapse event at {K}ick 'em {J}enny and to be linked to the formation of the horseshoe-shaped structure. {W}e estimated the volume and the leading-edge runout of the landslide to be ca. 4.4 km(3) and 14 km, respectively. {W}e modelled a sector collapse event of a proto {K}ick 'em {J}enny volcano using {V}olc{F}low, a finite difference code based on depth-integrated mass and momentum equations. {O}ur models show that the landslide can be simulated by either a {C}oulomb-type rheology with low basal friction angles (5.5{A} degrees-6.5{A} degrees) and a significant internal friction angle (above 17.5{A} degrees) or, with better results, by a {B}ingham rheology with low {B}ingham kinematic viscosity (0 < nu ({B}) < 30 m(2)/s) and high shear strength (130 < {I}-3 a parts per thousand currency signa{E}uro parts per thousand 180 m(2)/s(2)). {T}he models and the short runout distance suggest that the landslide travelled as a stiff cohesive flow affected by minimal granular disaggregation and slumping on a non-lubricated surface. {T}he main submarine landslide deposit can therefore be considered as a submarine mass slide deposit that behaved like a slump.},
