Montserrat Volcano Observatory: Introduction

The volcano had been silent for centuries -- so long that Plymouth, the island's capital, had grown up within easy reach of its slopes. Then, on 18 July 1995, the first phreatic explosions ripped through the summit, and the Montserrat Volcano Observatory was born out of necessity. Scientists from the University of the West Indies Seismic Research Unit arrived to set up an operational base almost immediately, building the monitoring infrastructure from scratch while the ground shook beneath them. What began as an emergency field station has evolved into one of the world's most sophisticated volcano observatories, a permanent institution that tracks every tremor, every gas emission, every shift in the dome that grows and collapses atop the Soufrière Hills.

This is not where you would build an observatory if you had a choice. It is where you build one when a volcano has already destroyed the southern half of your islan...

Montserrat Volcano Observatory: Science Under Political Pressure

They faced a volcano that had been dormant for so long that no living scientist had studied its behavior. The eruption was high-profile and hard to predict...

Montserrat Volcano Observatory: Watching the Dome Breathe

Photo credit CommonismNow, Public domain. The Soufrière Hills volcano operates on a cycle that the MVO has spent decades learning to read. Lava domes grow at the summit, building steadily for months or years until they become unstable and collapse. Those collapses generate pyroclastic flows -- superheated avalanches of r...

Montserrat Volcano Observatory: A Rotating Guard

Photo credit CommonismNow, Public domain. The MVO's leadership reads like a relay race run over three decades. In its early years, chief scientists rotated through rapidly -- the posting was demanding, remote, and unpredictable. Since 2000, a succession of directors has guided the observatory through the volcano's most a...
