In your previous lesson, you have learned that earthquake and volcanic eruptions are both dangerous. It is unpredictable to tell when they are going to happen, therefore there were suggested things you can do to protect yourself against their harmful effects. Direction: Write B on the blank if the precautionary measure should be done before an earthquake or volcanic eruption, D if it should be done during and A if it should be done after. 1. After the eruption, do not go back home right away. Wait for instruction when it is safe to return home. 2. Cover your nose with a mask or damp cloth when volcanic ash or dust is present in the air. 3. Prepare emergency supplies like flashlights, candles, matches, and first aid kits.​
