Volcanoes offer a variety of dangers, some if you are close enough and others whether you are close or farther away. The good thing is that scientists can more easily predict if a volcano is about to erupt giving you some time to evacuate, not like with earthquakes.
Hot and noxious gases, pyroclastic flows, and lava are all things to be aware of. Be prepared to evacuate as soon as the alarm is set off by the authorities. Don't hesistate to leave.
A pyroclastic flow can travel at very high speeds downhill. Obviously you want to do all you can to not get in the way. The heated gases in such a flow can be as high as 1000˚ C and may travel up to 700 km/h (450 mph).
are precursors to volcanic activity, which include earthquakes and rapid
ground deformations that may occur weeks, months or even years before
an eruption occurs. If a warning is given to evacuate because an
eruption is expected to happen, EVACUATE.
If you are going over this website it means that you are interested in taking responsibility for yourself and family in preparing for emergencies, or you are simply curious and want to see if preparations are for you. This isn't complicated at all to see the necessity of preparing for times of emergencies.
Emergencies do happen, and can happen to any one of us at any time. Have a look here if you are someone who is hesitant when it comes to preparing for times of emergencies.
The Eyjafjallajokull volcano
that erupted in Iceland early 2010 caused disruptions even in Europe,
as flights had to be delayed or cancelled due to the volcanic plume.
Many travellers were inconvenienced, but at least safe. Have a look at
the video below.
I know that some think that Mount Royal on the island of Montreal is a dormant or former volcano. However, this is erroneous. Mount Royal is part of the Monteregian Hills.
The following information used to be contained on the cities website, but for some reason is no longer there. Anyhow, the info they had makes it clear that Mount Royal isn't a dormant volcano. I'll quote a portion of the text here below from their site (when it was there in the past):
“Is Mount Royal a former volcano?
This is undoubtedly one of the most tenacious of Montréal myths. Ah, but no! Mount Royal is not a currently dormant former volcano. It is in fact one of the eight Monteregian hills...”
I had read from Natural Resources Canada that speaks of Mount Royal and Mont St-Hilaire. It had clearly stated that these mountains are not volcanoes. There are no active volcanoes in Quebec, even though they exist in the province.
Don't be influenced by people who think they know what they are talking about, when in fact all that they have is hearsay and misinformation from others, possibly mixed in with an over-active imagination as well.
Some of these people may be convincing and try and lead you to believe in dangers that don't exist in your area.
They may be well intentioned, but do your own research and as the saying goes, the truth will set you free.
A part of making preparations for times of emergencies is to properly assess the dangers or risks that are likely to happen in your area. If there is no volcano, then don't worry about it and prepare for what needs to be prepared for. Do a research to see if there are volcanoes in your own region and what their status is.
There are several types of volcanoes and eruptions that exist. Volcanoes may also cause other problems such as tsunamis when they erupt along a coastline. Dangers to health are many and varied. Hot gases and rock, fires, ashes, lahars etc.
I'll give you some links here so that you can learn more about volcanoes and the risks.
