TEHRAN, Young Journalists Club (YJC) -"I know there is supposed to be a tsunami warning alarm, but maybe it was outdated? I have no idea. We never get any warning from it," said Kurniawan, 46.
He said he was out at the time but his family escaped by wading through chest-high water to a neighbor's three-storey building.
While his family was spared, scores attending a beach festival in Palu were among those swept away, adding to the more than 1,600 deaths from the 7.5 magnitude quake and tsunami that have been confirmed so far.
Other survivors also said they heard no sirens, even though a tsunami warning was issued and then lifted 34 minutes after the quake, based on data available from the closest tidal sensor, around 200 km (125 miles) from Palu, which is on Sulawesi island.
As Indonesia struggles with the aftermath of the devastating quake, the spotlight has again been shone on the apparent lack of preparedness in a sprawling archipelago that suffers regular tremors, lying on the seismically active so-called Pacific Ring of Fire.
There was a major push in the region to improve warning systems after the 2004 Indian Ocean tsunami killed more than 120,000 in Indonesia alone, including establishing a network of 22 warning buoys to detect tsunamis that was put in place with German and U.S. help.
International agencies and countries poured $4.6 billion into the reconstruction of Indonesia's devastated Aceh province on Sumatra island, with new infrastructure such as strategically placed evacuation centers.
