Michael Glading was 16 stories up when the floor beneath him began to "move like crazy".
The North Shore man was sleeping in his Jakarta hotel room when a 6.5 magnitude earthquake rocked Indonesia's main island of Java, killing at least one person with reports of more deaths and injuries.
Glading is the tournament director for the New Zealand Golf Open and is in Jakarta for a golf tournament.
He told the Herald the quake was like nothing he had ever felt before, having only experienced small quakes before.
"Oh my god, the room was swaying from side to side. You almost had to plant one foot solidly on the ground. It was certainly 10 seconds where the building was really moving and you thought 'is this it?'
