“…The smooth morphology of the flanks of this cone contrasts with that of the flanks of the platform north and south which are dissected by numerous submarine canyons. More recently, Lindsay et al [2005a] confirmed this interpretation, on the basis of a new SeaBeam bathymetric survey aboard the NOAA ship Ronald H. Brown. They identified a hummocky mound of material at the opening of the horseshoe‐shaped structure that they interpreted as a debris avalanche deposit.…”

“…Located between 6 and 16.5 km from the present active volcano, this deposit covers an area of 67 km 2 with a mean thickness of 151 m and a total volume of 10 ± 0.5 km 3 . Lindsay et al [2005a] suggest that this voluminous debris avalanche deposit is the result of the collapse of a much larger (probably emergent) volcano (“proto” Kick 'em Jenny) than the present edifice. The summit of the present active cone of Kick 'em Jenny is only at 180 m bsl.…”

International audience[1] The 1997 Boxing Day collapse, a remarkable feature of the ongoing eruption of Soufrière Hills on Montserrat, has prompted new interest in the study of volcano stability in the Lesser Antilles. Building on a few cases documented in the literature, we have now identified at least 47 flank collapse events on volcanoes of the Caribbean arc where this type of behavior is characteristic and repetitive. About 15 events occurred on active volcanoes within the last 12,000 years. In the northern part of the arc, flank collapses are repetitive, do not exceed 1 km 3 in volume, occur in all directions, and are promoted by intense hydrothermal alteration and well-developed fracturing of the summit part of the edifices. In contrast, infrequent but large sector collapses, with volumes up to tens of km 3 , are typical of the southern volcanoes. They are always directed to the west as a result of the high overall slopes of the islands toward the deep back-arc Grenada Basin. Because Caribbean islands are small, a large part of the resulting debris avalanches have flowed into the sea thus contributing voluminous and sudden inputs of volcaniclastic sediments to the Grenada Basin. Deposits from such submarine flows have been identified during the recent AGUADOMAR and CARAVAL oceanographic cruises and traced to their source structures on land. Edifice collapses have a major influence on subsequent volcanic activity but also are of high concern because of their tsunamigenic potential

“…A similar eruption occurred from Montagne Pelée several years later, between 1929 and 1932, this time with no reported casualties (Perret, 1937). The 14 submarine eruptions from Kick 'em Jenny have been dominantly explosive, although in at least one case a lava dome was extruded (Lindsay and Shepherd, 2005;Lindsay et al, 2005b). The Soufrière Hills volcano on Montserrat has been erupting since 1995, resulting in significant impact on all aspects of the island.…”

We report on the process of generating the first suite of integrated volcanic hazard zonation maps for the islands of Dominica, Grenada (including Kick 'em Jenny and Ronde/Caille), Nevis, Saba, St. Eustatius, St. Kitts, Saint Lucia, and St Vincent in the Lesser Antilles. We developed a systematic approach that accommodated the range in prior knowledge of the volcanoes in the region. A first-order hazard assessment for each island was used to develop one or more scenario(s) of likely future activity, for which scenario-based hazard maps were generated. For the most-likely scenario on each island we also produced a poster-sized integrated volcanic hazard zonation map, which combined the individual hazardous phenomena depicted in the scenario-based hazard maps into integrated hazard zones. We document the philosophy behind the generation of this suite of maps, and the method by which hazard information was combined to create integrated hazard zonation maps, and illustrate our approach through a case study of St. Vincent. We also outline some of the challenges we faced using this approach, and the lessons we have learned by observing how stakeholders have interacted with the maps over the past ∼10 years. Based on our experience, we recommend that future map makers involve stakeholders in the entire map generation process, especially when making design choices such as type of base map, use of colour and gradational boundaries, and indeed what to depict on the map. We also recommend careful consideration of how to evaluate and depict offshore hazard of island volcanoes, and recommend computer-assisted modelling of all phenomena to generate more realistic hazard footprints. Finally, although our systematic approach to integrating individual hazard data into zones generally worked well, we suggest that a better approach might be to treat the integration of hazards on a case-by-case basis to ensure the final product meets map users' needs. We hope that the documentation of our experience might be useful for other map makers to take into account when creating new or updating existing maps.

“…Detailed investigations in 2002 had shown that hydrothermal venting occurred in the inner crater, which may have been the location of recent volcanic activity (Koch et al, 2002). Twelve eruptions have been reported for KeJ since 1939, with the eruptions reaching the sea surface in 1939, 1974, and 1988(Lindsay et al, 2005. The other eruptions were detected from seismic activity, with the last eruption reported in 2001.…”
