I actually felt the quake in Malaysia (I was still in my office in Cyberjaya) - the time was about 6.17pm on Wednesday.
I was concentrating on work when suddenly I felt my chair quiver and shake slightly from side to side. I initially thought I was having a headache as it felt like that...! My colleagues jumped up too, puzzled. However we decided to carry on with our work and didn't frantically leave the building or anything.
But we highly suspected Indonesia was literally giving off quake vibes.
