Need help pls (Startup Problem, disk0s2: I/O error)

Hi everyone, need some help here.

I tried to on my mac this morning and just like usual, the "chime" when off and the gray screen with the apple logo came out together with the spinning gear.

However today, it took longer than usual on the spinning gear and my mac osx did not startup and my mac switched off automatically.

I tried to reset my PRAM but this did not help.
I then tried to boot my mac osx in safe mode(+verbose) and I got the following error:

Any kind soul can help me? thanks in advance! Happy
