Initial movement (and it should be noted that 'Phuket' did not move, it was the entire plate upon which Phuket sits that moved - the Sunda plate that carries most of Thailand and all of the Thai/Indonesian Peninsula) was 27cm (co-seismic), followed by further shifts (post-seismic) over the following 50 days totalling 7cm. Between February and June 2005 drift continued. The authors' website (

According to Simons, the GPS-measurements in South East Asia are still taking place. “There is lag effect in the deformations. For example, Phuket, directly after the quake, had moved 27 cm, that value has now already increased to about 40 cm.”

This latter ('increased to 40cm') is, of course, not peer reviewed so perhaps you could be forgiven for questioning the 40cm figure and sticking to 34cm.
