This Wednesday and Thursday Singapore experienced the aftermath of the two earth quakes off Indonesia.

The effect of the first earthquake to our condominium was worrying. At the 21st floor, it felt like the tower was vibrating. On top of this unpleasant experience (that people on the ground hardly noticed), the fire alarm of our neighbour condominium went of at 4 AM Friday morning...

Anyway, all's well that ends well.
