No, this isnt fair, there are no/very few accurate tecniques to predict such events so its unfair to blame geologists for something they can do very little about.
The boxing day tsunami is unique, what failed it was communication. There was no way of predicting when an earthquake would occur, but the occurance of such events was know. When it comes to the tsunami, there was a massive failing, people knew it was coming but failed to tell areas that were affected beforehand. Although saying that the problem then lies in actually telling the people, lack of radio/tv etc.
Its not just a geologists job to save lives, its a whole range of people who all need to communicate with each other effectivly.
I think that there should be more funding for the equipment needed to monitor areas in the poorer regions of the world. Its normally the poorer people that are effected the most, no insurance etc
Once again the management is down to various stakeholders, government, NGOs, scientists, WB, IMF, UN etc
As i said above! if money was effectively invested into planning, preparing, infrastructure and education then more lives would be saved.
As nature events of course no one is to blame, but for the knock on effects yes i believe people are to blame for making them worse
phew i think that makes sense! not sure
