I have a list of gauge stations like this

Code X Y

12345678 -35.74 -18.24

01234567 -38.71 -18.42

...

And a list of disasters events like this

Date X Y

2016/1/1 -35.73 -18.24

...

I need to find the nearest gauge station for each event, than add the code of corresponding station as a row on disaster matrix:

Date X Y near_station

2016/1/1 -35.73 -18.24 12345678

...

Any suggestions how can I do this on MatLab?

There is a built-in Matlab function dsearchn. Alternatively, you can write your own code using an approach similar to the one given for another question here.

@Aquatris, you can move this comment to the answer section, because it actually answers the question. Feel free to put answers in the answer section without example code as well.
