Living near a volcano..

Plans  taken by people and government who live near a volcano: 

1) Listen to scientists. There are many new devices that can tell when a volcano will explode. Sometimes these warnings come days before an explosion. Although sometimes warning only come a few hours before the explosion, it still gives sufficient time to evacuate.

2) Usually governments would have set up a plan of what to do once a volcano has exploded. There need to be health workers, vehicles, and medical care ready to go. They need to have trucks prepared to move dirt. There should be food and water stored in a safe place.

3) Governments usually observe volcanoes activities very closely with the help of volcanologist. 

4) Government build walls in the way of lava to block or divert its flow


5) After a eruption, government would have a movement plan for the citizens. They would have allocated places to evacuate to.
