Introduction
In this paper the Soufriere Hills Volcano will be analyzes in several different parts; an introduction to the Soufriere Hills volcano, the composition of the magma and lava in the volcano, other characteristics of the magma and lava, ash production from eruptions, pyroclastic flows, volcanic activity before the 1995 eruption, the 1995 eruption, cyclic activity within the volcano, and potential hazards of the Soufriere Hills volcano.
Soufriere Hills volcano is located in the south central part of the British overseas territorial island of Montserrat near the northern end of the Lesser Antilles volcanic arc in the West Indies (Young et al., 1998). The island of Montserrat is comprised of a number of volcanic centers that range …show more content…
Since their arrival, there have been three seismically volcanic crises that erupted at approximately 30 year intervals in the years 1897 to 1898, 1993 to 1937, and 1966 to 1997 (Aspinall et al., 1998). The island of Montserrat lies on the Caribbean plate and is influence by the boundary between the North American plate and the Caribbean plate (Aspinall et al., …show more content…
The first type of plagioclase found is known as sodic phenocrysts with contain oscillatory zoning (Murphy et al., 1999). The second type of plagioclase is reverse zoned large sodic phenocrysts and microphenocrysts that also have oscillatory zoned cores (Murphy et al., 1999). The third type of plagioclase is reverse zoned dusty sieve-textured crystals that have clear oscillatory zoned sodic cores that contain sieve-textured calcic mantles (Murphy et al., 1999). The fourth type of plagioclase found is a very rare and high calcic and normally zoned (Murphy et al.,
