Palu, Indonesia (CNN)Puteri Pratiwi was riding home with her cousin, Ita, late on Friday night in her hometown of Palu when she felt the ground shudder beneath her.
The 18-year-old fell to the ground and was still sitting in shock when she saw the monstrous wave surging up the bay toward her city.
“I shouted at my friend, ‘Let’s run fast! Run!’ We ran but she turned back to save the motorbike,” Puteri told CNN from her hospital bed outside the Undata Hospital in Palu. She survived the tsunami holding onto a pillar. Three days later, she found out her cousin had been swept away and died.
