On planet Earth there are 500 active volcanoes. Every one a potential killer. Once they erupt nothing can stop them. One of the deadliest of all – a supervolcano – is here in America beneath Yellowstone National Park. A super-eruption here will be like nothing seen before.

Yellowstone: It’s breathtaking beauty has attracted both settlers and tourists for thousands of year. ibid.
Yellowstone is a disaster waiting to happen. ibid.
The slumbering volcanic peak of Mount St Helens. In its shadow one of America’s most beautiful national forests, a magnet for vacationers seeking the great outdoors. But then, without warning, the volcano erupts; in just 4 minutes the blast flattens 220 square miles. Huge muds flows surge down 150 miles of river valleys. 57 people die.

Mount St Helens spews smoke and ash higher than a mile into the sky. The volcano has woken up from a 123-year sleep. ibid.
A Caribbean island paradise and a volcano wakes after lying dormant for centuries. With the lives of 10,500 people at stake, volcanologists rush to the scene. Then a catastrophic eruption sends an avalanche of re-hot rock and ash cascading down the mountain. Seconds from Disaster s3e13: Eruption at Monserrat
Montserrat lies directly on a geological subduction zone; this is one of the most seismically active parts of the planet’s crust. ibid.
A month after the first blast, another larger phreatic eruption fires a cloud of ash, mud and steam two kilometres into the air. The vibration rocks Montserrat. The locals stare nervously at the darkening skies. The south-west of the island is showered in a thick cloud of volcanic dust. ibid.
Pyroclastic Flow: They have caused over 40,000 deaths in the last century alone. ibid.
The volcano hasn’t finished yet: nearly three months later it fires its first pyroclastic flow down the eastern slope of the mountain heading for the coastline. The flow travels just two kilometres and no-one is hurt, but it is clear that volcanic activity is intensifying again. ibid.
The island experiences its first magmatic eruption. ibid.
It’s prepared to blow with a deadly force that will destroy this island paradise. ibid.
A daring helicopter rescue gets underway. ibid.
The scene is like a modern-day Pompeii. ibid.
19 people lost their lives on 25th June. ibid.
