Thee 1995- Present Eruption Crisis

Te pory erupcji is one of te długowieczne continuous dome- forming eruptions in contexded history, chacrized by y district fazes of intensy activity and relative quiet. Its timeline is marked by key events that have shaped thee island 's present condition.

Timeline of Major Events

Wołcanic unrest with a serie of small phreatic (steam-trawn) explosions in July 1995. Byte fall of that yes, a small lava dome had emerged. Activity escated throut 1996 and 1997. In June 1997, a major dome falle generate d pyroclastic flows that reached thee ouskirts of Plymouth, leading te thel final ecupation of thee capital. The mect destructive event existred on december 26, 1997.

The Plymouth Exclusion Zone

Once a bustling colonial capital with a population of around 4,000, Plymouth now lies buried under meters of volcanic debris. It is a modern-day Pompeii, with the roofs of buildings barely visible above the ash and lahar deposits. Access to Plymouth and the surrounding southern exclusion zone is strictly controlled by the Montserrat Volcano Observatory (MVO) and police. The area remains highly dangerous due to the threat of pyroclastic flows, volcanic gases, and unstable ground. The exclusion zone has fundamentally redefined the island's geography, confining habitation and development to the narrow, safer northern region.

Ongoing Volcanic Activity
