In addition, Associate Prof Dr Amorn Pimanmas, an expert on earthquakes and structural engineering from the Sirindhorn International Institute of Technology, Thammasat University told The Phuket News that the quake is more than likely to be an aftershock as it occurred at the same location.
“It happened in Koh Yao Tai again so it is more likely that is is just an aftershock. However, according to the Klong Marui Fault line small quakes like this can be signs for bigger earthquake ranging from 4-5.5 Richter.
