It depends on the type and size of the eruption. Most volcanic eruptions do not cause more than localized disruptions. Extremely large eruptions can cause ash to fall thousands of miles away and change weather patterns worldwide.
to the very bottom.
The blast of the volcano, the wind, and how light the ash is all affect how far it will travel.
well you could just get as far away from the volcano as possible
The way a volcano is being formed, depends on the type of lava. Cinder cone volcanoes is made from andesitic lava. This type of lava is especially thick, and therefore is won't be able to ''run'' very far from the volcano. In this way, each time a cinder cone volcano erupts, it will create a new layer of lava, making the volcano higher and higher each time, but it will not increase its base area very much. It's different with shield volcanoes. They are made from another kind of lava which will advance very far from it's vent. Therefore the shield volcano won't often be very tall, but it can have a very large base area
If the volcano is not active and you don't fall too far, then yes.
NO
A shield volcano is made from lava flows that flow far, making a very wide, not very steep mountain. A cinder cone volcano is the most common type of volcano. It is formed from volcanic fragments and is very steep sided, although not always extremely tall. They usually have just one main vent, and can also sometimes form from a vent of a larger volcano, growing and becoming a whole new volcano. Composite volcanoes resemble very large cinder cone volcanoes at first, but have bigger particles making them up usually and also have multiple vents more often. They also are potentially more explosive.
by either not being there, or by running away very quickly! The forces and the pressures are far greater than man can plug!

It didn't they didn't get very far at all.
Although Singapore is not very far from a subduction zone, it is beyond the zone in which the subduction produces volcanic activity. Additionally, Singapore is geographically quite small, so even if it were in a belt of volcanic activity, there probably would not be a volcano in Singapore.
If hot material doesn't make it very far, some snow that the material didn't reach may remain. In other cases snow may fall on a volcano after material has cooled down.
