Malaysia does not have volcanoes. So not much chance of this happening. But when a big volcano (super volcano) erupts, it will cause a lot of ash to be deposited in the atmosphere. This ash can block the sunlight, and result in winter like conditions all over the world. Even though the volcano is far away (like thousands of miles away).

Normal volcanoes normally do not cause major disruptions. But super volcanoes, yes.

One example of super volcano is Lake Toba in Sumatra. This was a super volcano that caused mass extinctions in the past.
