AB: The SoufriŠre Hills Volcano is located on the southern half of the Caribbean island of Montserrat. Montserrat is situated in the northern part of the Lesser Antilles, which is a volcanic island arc formed along the junction of the Atlantic tectonic plate and the Caribbean plate. The SoufriŠre Hills Volcano began erupting in 1995. On July 12, 2003, a lava-dome of the volcano collapsed and led to several days of explosions that rocked the island and injected ash into the atmosphere. This presentation will focus of the transport mechanism of the volcanic ash from the island of Montserrat to the southwestern coast of Puerto Rico. Trajectory models will be used to show the air mass history and movement of the ash during transport. This data will be supported with In situ measurements of aerosol particle size and mass distributions taken on the southwest coast of Puerto Rico in the days before, during, and after the lava-dome collapse.
