On Sunday, Mount Sinabung on the north of Sumatra island erupted; and on Monday it erupted again.

The volcano was inactive for four centuries or four hundred years; since 1600.

It shot ash 2 km or 1.5 miles into the air.

The eruption triggered the highest red volcano alert.

About 21,000 people left their houses because it is very dangerous to be near a volcano if it erupts.

Hot lava and burning rocks from the volcano can burn houses, trees and everything on its way down the volcano.

Volcanic ash covered trees, plants, houses and everything in the area.

People leaving the area were also covered by ash.

Some flight to Medan and Sibolga were delayed.

In April, 2010 the volcanic ash from Eyjafilljallajokull glacier in Iceland closed airspace and airports all over Europe and thousands and thousands of passengers were stranded all over the world.

I wonder if Malaysian airspace and airport will be closed if the volcanic ash problems get worse …
