圣文森特的soufri<e:1>火山从1971年10月爆发到1972年3月，80 × 106平方米的玄武岩安山岩熔岩被悄悄地挤进了这个一英里宽的火山口。这次喷发主要发生在水下，发生在180米深的火山口湖，导致了一个陡峭的岛屿的出现。这次喷发的温和性质和没有地震活动，与1902年至1903年爆发的高度爆炸性性质形成了直接对比。
The Soufrière volcano in St. Vincent erupted from October 1971 to March 1972, as 80 × 106m3of basaltic andesite lava was quietly extruded inside the mile-wide crater. The eruption was largely subaqueous, taking place in the 180-m-deep crater lake, and resulted in the emergence of a steep-sided island. The mild character of the eruption and the absence of seismic activity stand in direct contrast to the highly explosive character of the eruption of 1902 to 1903.
