earthquake?

I was just minding my own business in the office when just a few minutes ago my chair started to rock back and forth. Earlier in the morning i had to give a sample of blood so i thought my heart started to beat vigorously thus causing the shake. I paused for a moment and composed myself but i felt fine. I looked at the computers coz i tot it might be the computers acting up. But no it's not. Then suddenly i was IMed by my 2 colleagues asking me whether i felt any tremors...confirm liao. Then i got news from other friends that tanjong pagar area felt the tremors and there were ppl who went off for early lunch. Then even more amazing, someone in KL felt it too. I think it's a huge earthquake to affect that kind of range..let's wait and see what's going on.
