It is very hard to predict an earthquake; only vague predictions can be made from looking at historical patterns of eruptions. However, perpetration can be made in areas that are prone to these natural disasters.
Earthquake drills can be practiced in offices and schools.
Buildings can be built with counterbalances and rubber foundations to withstand even powerful earthquakes.
Computers can cut off gas supplies as soon as an earthquake breaks, to minimise fires.
Tsunami walls and shelters can be built in areas prone to this kind of disaster.
Families can keep survival kits in their homes.
