The aftermath of a disaster. Recovery following the volcanic eruptions in Montserrat, West Indies.
The people of Montserrat have experienced serious volcanic eruptions since the middle of 1995. These resulted in the evacuation of the capital town Plymouth in 1997. An exclusion zone was declared and two-thirds of the original population of 10,324 migrated abroad. The remainder was left to initiate the recovery process. This paper reviews the action taken to maintain and then restore the healt...
متن کاملVolcanic ash and respiratory symptoms in children on the island of Montserrat, British West Indies.
BACKGROUND In July 1995 the volcano on the West Indian island of Montserrat erupted after being inactive for several hundred years. Since then, clouds of ash have been released intermittently from the volcano. Some of this ash is <10 micro m in diameter and therefore respirable. Concerns were raised that the particles might cause respiratory problems. AIMS To evaluate whether ashfalls had any...
متن کاملMagma flow instability and cyclic activity at soufriere hills volcano, montserrat, british west indies
Dome growth at the Soufriere Hills volcano (1996 to 1998) was frequently accompanied by repetitive cycles of earthquakes, ground deformation, degassing, and explosive eruptions. The cycles reflected unsteady conduit flow of volatile-charged magma resulting from gas exsolution, rheological stiffening, and pressurization. The cycles, over hours to days, initiated when degassed stiff magma retarde...
متن کاملAntennal morphology in the family Dolichopodidae (Diptera)
Nine hundred eighty species belonging to 182 genera of 15 subfamilies of the family Dolichopodidae were investigated to study antennal morphology. Length measurements of scape, pedicel, postpedicel and arista and height measurements of postpedicel bases were performed, and 4 ratios were selected. Use of morphometric characteristics of Dolichopodidae antennae allows meaningful distinctions betwe...
متن کاملAssessment of the exposure of islanders to ash from the Soufriere Hills volcano, Montserrat, British West Indies.
BACKGROUND AND AIMS The Soufriere Hills volcano, Montserrat, has been erupting since July 1995 and volcanic ash has fallen on the island throughout most of the eruption. The ash contains substantial quantities of respirable particles and unusually large amounts (15-20%) of the crystalline silica mineral, cristobalite. The purpose of the surveys described here, undertaken between December 1996 a...
