1. Can we stop disasters from happening?
I don't think so. Disasters such as volcanoes and earthquakes can't be controlled by humans. But for some cases, such as floods, are caused by humans contributing to global warming, which can be controlled.
2. Can people be informed of the diasters beforehand? If so, how?
Most likely yes. When there is an earthquake coming, there is an instrument used called seismograph. It is an instrument used for recording the intensity and duration of an earthquake.
Some of you may have even seen it before on television, which I did.
But my question is "Whenever we walk, or jump, or even when an aeroplane is landing, will the vibration affects the seismograph?" Please tag!
When there is an earthquake arriving, signs of smoke and ashes spewing out of the volcano can also be seen.
