Volcano, Physical and Chemical Changes

The eruption affected the place by destroying buildings and properties, injuring people, loss of lives, and the panicking and crying of the citizens.

We should be alert so that when disasters like this happen to our community, we’ll know what to do and we can evacuate safely. We should be trustworthy so that other people will believe us and we should trust one another. We should be caring and concerned to each other and other people. In disasters like this, we can do small heroic acts which can save lives of millions of people that means very big to them. We should do heroic acts not because we want to be recognized but because it came from our heart. Last but not the least, we should have teamwork and cooperation so that problems can be solved quickly and we can aim for success.
