How do individual actions affect the community immediately following a natural disaster? (How did the community help themselves?)

Individuals can help in the earthquake disaster by 3 rules. The first rule is looking out for there neighbor if they see that they are stuck within the rubble of the earthquake . The second rule would to get yourself and your family out of the Quake zone. The third rule is always helping in a dire need like this one here if you are not able to help then please provide supplies to the teams that are willing to go searching for people. A community can not thrive on one man or woman they need all arms say if your home was destroyed in the quake  I would hope your Community would be there to patch you up with there volunteers nobody can stand  alone in this quake disaster if you do so then there is no Community .

a is the answer i believe.
