We have had two solid tremors felt in various parts of the Republic and all thanks to the major quakes in neighbouring Sumatra, some 530 kilometres away.
Coming as I do from the 'Shaky Isles' of New Zealand I am no stranger to these but the sensation of experiencing an earthquake does not get any more pleasant with age.
We were trained at a very early age to get under a door frame (or failing that a strong table) whenever the ground started to rumble and rock. My Singaporean colleagues however have had no such training, as the look on their faces clearly showed when we experienced the second quake one morning.
Several just sat at their desk with frozen expressions of uncertainty no doubt wondering why I had leapt from my seat and was heading for the nearest door frame.
Suitable door frames are hard to find in Singapore. For a start most buildings are not made with wood and secondly most have partitioned spaces so solid rooms are anything but.
Interestingly given the geology of the country not everyone felt the tremors. The first big Padang 'quake took place without us feeling it in our condo whereas people on the East Coast and Raffles Place felt the full effects and evacuated their buildings.
Another worry must be the reclaimed land upon which a significant part of Singapore is built. Liquefaction is a major destroying force during earthquakes and reclaimed land however well compacted is very prone to this.
The vision of the soon to be launched Integrated Resort (pictured) half submerged would give new meaning to the title of 'Marina Bay Sands'.
I expect through that most new structures have been built to withstand the earthquakes of the strength we might experience here. Fortuitously Singapore does not stand on a major fault line unlike its near neighbour, Indonesia.
It is just a matter of time (and a short time at that by all accounts) that the pent up pressure of the Indian/Australian and Eurasian tectonic plates on the western side of Sumatra will be released in a major 'quake of nine magnitude.
Professor Kerry Sieh of Nanyang University's Earth Observatory has publically stated that the recent quakes are 100 times smaller than the big one when it comes; a less than comforting thought.
Some twenty years ago I saw a map of the faults lines that criss cross New Zealand's capital city Wellington. At the time I raised the question with a colleague "Could an earthquake somewhere else trigger an event in another location"?
"No" was the unequivocal reply, "Such events are very specific to the location".
It would seem now that his analysis was flawed as scientists have recently discovered that the major 2004 earthquake in Sumatra may have weakened the San Andreas fault, 8,000km away in California.
If this is indeed the case being a mere 500 kilometres away from the Big One when it strikes is not that reassuring.
I shall be stocking up on half price moon cakes to tide me over such calamities should they occur in the next fortnight. The Autumn Festival concluded last night and the cakes in question are always heavily discounted after the event.
