In little more than half a century, Sulawesi has endured dozens of earthquakes, landslides, floods, tsunamis and volcanic eruptions.

NYT

  • “….At least 1,649 people have been confirmed killed by the twin natural disasters on Sept. 28. Many more are believed to have died, been buried under soil, swept away by waves or trapped in a tangle of crushed buildings that will take months, if not years, to clear.….”


What happened to Indonesia’s early warning system for tsunami detection?

NYT

  • Indonesia’s system, completed in 2008, consists of seismographic sensors, buoys (record changes in the sea level), tidal gauges (measure changes in sea level every 15 minutes and send the data to the national meteorological agency) and GPS.
  • None of the 22 buoys was operational (vandalism and lack of maintenance)
  • No data observation equipment near enough to Palu to measure tidal changes in the immediate area.
  • After Friday’s earthquake struck, all three tsunami waves hit the area fewer than 11 minutes later.
