All Saint’s Day, 1755: A series of 3 earthquakes + a 20′ tsunami hits Lisbon, Portugal, killing as many as 50,000 people

History Channel


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.

Mass burials in Indonesia & hundreds of aftershocks continue to reverberate around Central Sulawesi, hindering rescue operations.


The Ring of Fire


On the Indonesian island of Sulawesi, the quake and tsunami killed at least 832 and injured another 500.

  • Indonesia is prone to earthquakes.
  • It lies on the Ring of Fire – the line of frequent quakes and volcanic eruptions that circles virtually the entire Pacific rim.
  • The injured are being treated in tents because of damage to hospitals.
