What were the hazards of the Montserrat eruption?
The principal hazards are pyroclastic flows, and fragments of volcanic rock ejected by explosions. Pyroclastic flows are avalanches of hot lava fragments and volcanic ash which can move at speeds of over 100 kph and are highly destructive and invariably fatal to people in their path.
Where are the volcanic hazards in the US?
The eighteen very highest threat volcanoes are in Alaska, California, Hawaii, Oregon and Washington.
Where is Montserrat exclusion zone?
An exclusion zone, encompassing the southern half of the island to as far north as parts of the Belham Valley, was imposed because of the size of the existing volcanic dome and the resulting potential for pyroclastic activity.
Can you visit the exclusion zone in Montserrat?
There have been on-going volcanic eruptions in the southern half of the island since that time, and that part of the island (the exclusion zone) is now ash-strewn and inaccessible. The northern half of the island is untouched, as beautiful as it ever was, green and lush; visiting it is perfectly safe.
What caused Chances Peak to erupt?
Chances Peak is on a destructive plate margin. The volcano itself is in the middle Caribbean plate, but this is because the North American Plate and the Atlantic Plate subducts beneath it, causing a buildup of pressure to form a volcano.
Why do people live near volcanoes?
People live close to volcanoes because Geothermal energy can be harnessed by using the steam from underground which has been heated by the Earth’s magma. This steam is used to drive turbines in geothermal power stations to produce electricity for domestic and industrial use.
What volcano in the US is most likely to erupt next?
Mount St. Helens
We know that Mount St. Helens is the volcano in the Cascades most likely to erupt again in our lifetimes.
Does Mt St Helens still steam?

Is Montserrat a high ash hazard?
For the mean wind direction and speed around Montserrat the impact on areas 3, 4 and 5 will be high. Areas 1 and 2 will be more marginally affected. Fine Ash Hazard It is expected that further ash falls from pyroclastic flows and explosions will occur.
Could the north of Montserrat be affected by an eruption?
An important issue is the occurrence of eruptions that are sufficiently large that they could affect the north of Montserrat. While this possibility exists, the likelihood is very low and should be viewed in the context of other natural hazards to which the island is continuously exposed.
