Indonesia Earthquake

Twin-quakes hit West Sumatra [Indonesia] on Tuesday, causing Singaporeans to shudder. A death toll of 52 was reported as of today. The first quake struck at 11.49am with a magnitude of 6.3 and the second at 1.49pm with a magnitude of 6.1. Both were considered deep earthquakes.
An interesting fact i learnt from the newspapers was the classification of different quakes according to their magnitudes.
  • Shallow Earthquake - occurs randomly with a magnitude between 1 and 5
  • Deep Earthquake - occurs every 20-30 years with a magnitude between 6 and 8
  • Subduction Earthquake - occurs every 100-1000 years with a magnitude greater than 8

Unfortunately, Indonesia happens to be within the Pacific ring of fire, which makes it prone to earthquakes. The worst hit quake was in Boxing day in 2004 where the tsunami struck, raising the magnitude to 9.1.
This time round, the epic centre of the quake was pretty strong, resulting in tremors felt in both Singapore and Malaysia. Amazingly, i felt nothing on both occasions. The Central Business District [CBD], Ang Mo Kio, Bishan, St Andrew's JC and Ngee Ann Poly were some of the affected areas in Singapore.
Dickson was mentioning to me that Blk 72 of NP was shaking badly, which gave him a scare. Haha.. Would it have occurred to me, i guess i would be swooned by the dizzy spell.
Given the fact that Singapore's building infrastructures are 3 times stronger than their original strength, tremors would not cause them to collapse. However, one can never be certain that accidents will not happen. What if it does?
Are the measures lain out by SCDF sufficient to control the entire situation? From the news reports, many are definitely not prepared for it. People are still taking the lifts which is basic knowledge that they should be avoided in case they jam or collapse. Some only reacted when they received messages from their friends that there were tremors and told to evacuate immediately. The buildings do not wait for one to leave before they come crashing down. Therefore, it is important that more of such exercises be carried out to raise awareness and preparedness among Singaporeans.
This is yet another tragic disaster...
