When the earth shook with incredible power, she grabbed seven year old Fikri, her great nephew, and rushed out of the house.

They had been cooking together, packets of yellow rice with fried chicken to sell at a beach festival to mark Palu city's anniversary."With things crumbling and falling around them, they ran out into the open.

They were terrified that they would get trapped inside," says her sister Selfi Salilama, Fikri's grandmother.When the earth stopped shaking, Marta left Fikri with some neighbours who had gathered around a horse statue that sits on the Palu bay.She then went home to turn off the stove.

"When she came back Fikri was gone," says Selfi.

What she found was a scene of horror, a trail of destruction left by gigantic waves that had pounded the bay.

He had been clingy that day, she remembers."He wanted to be carried all the time, so I carried him around on my hip.

He finally got bored and asked to be put down and went off and played in the sand," she says.

When the first quake struck she tried frantically to reach him but failed.

It was chaotic, she says, with people running in all directions as the earth threw them around."When I got closer to the shore I saw a wall of black water heading towards me."Image caption "I ran as fast as I could, I had no idea where I was running" With the monstrous waves about to pound the bay, she could look no more and ran."I ran as fast as I could, I had no idea where I was running.

When the water swept me away I clung on to a motorbike." The waves finally dumped her in the parking lot of a hotel.

She had survived.

"I didn't recognise her at first, because she was covered in mud and blood and was crying.

I turned to someone I knew and said I am looking for my wife and they said - that's her!" "Her hair was caked with mud and blood, it was like instant noodles.

I picked her up and cried out for help."A passing motorbike rider took them to the nearest hospital.

"I was worried she would lose too much blood.

There were lots of aftershocks, it was terrifying," he remembers.

When he came across a body of a child he broke down and cried."In the morning the grandfather, Asmudin, joined the search.

His grandmother, Selfi Salilama, says they feared he, too, was dead.

"At the hospital we opened body bag after body bag that had a child in it," she says.

"Each time a wave of fear washed over us.

And we would say 'Allah make us strong enough to do this' - each time hoping it wasn't Fikri.""We were almost certain that we had lost him.

We knew his 10-year-old brother had died.

But in my heart I had a little hope that perhaps Fikri had run away in time."Image caption Selfi Salilam feared both her grandsons were dead Fikri's parents find out Fikri's parents live and work 600km away in Gorontalo.

I was just speechless.
