The eruption of Soufrière Hills Volcano, Montserrat (1995-1999) has displayed a wide range of volcanic phenomena: growth of an andesitic lava dome, generation of pyroclastic flows by lava dome collapse and by fountain collapse in explosive eruptions, Vulcanian and sub-Plinian explosivity with accompanying tephra fall, entrance of pyroclastic flows into the sea, sector collapse with formation of a debris avalanche and a high-velocity pyroclastic density current, and generation of lahars. New phenomena include: cyclic patterns of ground deformation linked with shallow seismicity and eruptive activity; pyroclastic flows formed by rapid sedimentation from pyroclastic surges; and an unprecedented slow escalation of eruption intensity. Magma pulsations with timescales of hours to years have been recognized. Transitions from extrusive to explosive activity were triggered by major dome collapses. Relationships between magma ascent dynamics and geophysical signals have been elucidated. Ascending water-rich andesitic magma becomes Theologically stiffened by degassing and groundmass crystallization. Large magma overpressures are consequently developed in the upper conduit, causing shallow seismicity, radial patterns of ground deformation, and cyclic pulsations of eruptive activity. Lava dome growth involved heterogeneous deformation with formation of spines and lobes along shear zones. Collapse of the pressurized dome resulted in substantial pyroclastic surges forming above pyroclastic flows. Influx of hydrous mafic magma remobilized hot crystalline igneous rocks at depths of 5 to 6 km to form crystal-rich andesitic magma and triggered the eruption.

Was the eruption of montserrat a composite volcano?
No. The term compostie volcano describes a kind of volcano, not a kind of volcanic eruption. The Soufrière Hills on Montserrat is indeed a composite volcano, however, whether it is erupting or not.
How long did Montserrat last for?
it was dormant for 400 years before it erupted.
How many people died during the Montserrat Volcano eruption?
no-one was injured !!
What were the short term responses of the Montserrat volcano eruption?
Something happened
What plates were involved in the montserrat eruption?

When did montserrat first errupt?
July 18, 1995 was the volcanos first recorded eruption in recent history.
What was the death toll in the 1995 soufriere eruption?
The 1995 eruption of Soufriere Hills volcano in Montserrat resulted in 19 deaths. It was a small eruption, but it triggered a larger and more destructive eruption that occurred in 1997, causing further devastation and loss of life.
What is the conclusion to the complexity of the montserrat eruption?
/
How big was the Montserrat eruption?
very big
Was montserrat eruption predicted?
The Montserrat eruption was predicted by scientists. They warned the British government that the volcano was still active and would erupt again. The predictions were ignored.
What is the area of montserrat?
Montserrat is an island in the Caribbean. It is one of the Leeward islands and at the time of the famous eruption it had 12,000 inhabitants
When was Montserrat Championship created?
Montserrat Championship was created in 1995.
What were the responses of the eruption on Montserrat Caribbean?
people were shocked...'omg'
Were did the montserrat volcano erupt?
1995 is the year the montserrat volcano erupted.
How many people died during the Montserrat Volcano eruption?
