The area surrounding a volcano which is in danger of eruptions, dangerous gasses, seismic activity, high temperatures, landslides/slips, lahars and pyroclastic flows etc.
its dangerous because if the volcano erupts your entire life can be ruined forever
because it is a active volcano
No one, unless it erupts in which case everyone is.
People living near a dormant volcano may be unaware of the danger. A dormant volcano may become active at any point of timeand the people living near the volcano may not realize it is about to erupt.
The volcano erupts that the people did not have any time to evacuate to a safe place and many lives are in danger.
This can depend on a number of factors, such as the size and shape of the volcano, the shape of the landscape, the nature of the lava, etc. If the volcano is on an island, it is most likely to be a shield volcano, with a lava flow which is slow moving, and easy to outrun, so the danger zone is small. Areas with more explosive composite volcanoes and thicker lava have huge danger zones of many km, because the steep flanks of the volcano allow the pyroclastic flows to build up velocity and travel further distances. The ash is the biggest issue, the UK faced airline shutdown when an icelandic volcano eurpted in 2010, which still classes as a danger zone.
20-30%
When the volcano has been extinct (without an eruption for at least 10,000 years) is the surrounding area considered safe.
Preferably evacuate, get out of there
they usually are entitilted to losing their homes in the future and are in fisk of danger
Yes, because you never know when the pressure can build up and blow the top off the volcano but if a volcano is dormant or extinct it is very unlikely.
