By building massive, high walls. The cost of building this protective wall would be very less expensive to the cost of damages caused by tsunamis. If China has built their huge and very long wall a long time ago, why that tsusamis-proof wall can't be constructed today in cities were tsunamis are predictable to happen?
Build your town well away from the coast.
A tsunami is a force of nature and the result of a power earthquake , so a warning system might help get people to higher ground and away from the ocean.
by proper information systems, proper media coverage, detection of tsunami warnings in advance, proper evacuating system, taking safety measures.
It can't be because it can't be prevented and there is no way to know when one will happen.
There is a certain type of wall that will hold back a tsunami. However, it doesn't mean nothing will get damaged.
It causes damage to buildings and infrastructure,animals,plants and humans.
It couldn't have been minimised that much. The problems with tsunamis is that we are still unable to predict them. Things such as high walls and stronger buildings along with better awareness from the people may have minimised the impact. Also pipelines can be fitted with smartmeters which shut of gas and whatever else when they are broken therefore preventing fires, though this wasn't a major issue for the 2004 tsunami.

Tsunamis does total devastation destroying everything in its path.
With proper mitigation, evacuation and informatory systems damage can be minimized leaving minimum deaths but loss of property can only be prevented to a very small extent.
