Because it happened within the Australian Plate rather than at a plate boundary, shockwaves from the quake travelled more efficiently to Darwin than to cities closer to the epicentre.
If you've never heard of a form of wave called a 'seiche' – which can occur in swimming pools during earthquakes – this is your chance to catch up.
Research into volcanic activity in the waters off Indonesia shows how active this region is and how destructive landslide-caused tsunamis can be.
Making the word smong part of the Indonesian vocabulary does not mean removing the word tsunami. Smong should be a source of pride in how local knowledge protects us from disaster.
Earthquakes and tsunami in Indonesia this year did not only leave a deep sorrow. It made us rethink the relationship between humans, technology and nature in Indonesia.
Last month's earthquake in Sulawesi, Indonesia was large, but not huge. It was the aftereffects that made it so devastating.
To stay safe in a tsunami, remember that the sequence of waves may occur over hours to days, and the biggest wave in the sequence could occur at any time.
Developed countries focus on technology, but lullabies can sometimes have a greater effect.
The early warning system installed after the 2004 Boxing Day tsunami hasn't lived up to expectations.
Indonesia's tsunami early warning system failed to provide adequate warnings to people in Palu.
A combination of tectonic plates, geography and poor infrastructure make Indonesia vulnerable to deadly tsunamis.
Local knowledge and awareness of the risks of tsunamis can better prepare people when disaster strikes.
Caught in the middle: Lombok and Bali are exposed to earthquake and tsunamis risk due to a tectonic plate boundary to the south, but also a unique zone of activity that thrusts to the north.
Survivor's guilt is arguably an instance of good character, an emotional expression.
A new method of analysing underwater sound waves has led to the creation of a faster, more informative tsunami early warning system.
Post-tsunami the position of women in Acehnese society has in many ways changed and, arguably, worsened compared to their historically high status.
As well as thousands of deaths and huge destruction, Japan's 2011 tsunami carried potentially invasive species _en masse_ across an entire ocean.
A 8.1 magnitude earthquake hit off the coast of Mexico on 8 September 2017. Fortunately, initial fears of a damaging tsunami hitting the coastline now appear unfounded.
Sometimes 'stuff' isn't just stuff.
As the rich move away from disaster-prone areas, the poor may be left behind.
