Chiang Mai was hit by 94 minor quakes measuring from 4 magnitude on the Richter scale to 1 magnitude in the past one month, but there is a 5 percent chance that the northern capital may be struck by a stronger tremor of up to 5.5 magnitude within a cycle of 17 years.
The latest tremor measured at 4 magnitude on the Richter scale was reported at 4.08 am today with its epicenter at a depth of ten kilometres from the surface in Tambon Mae Win, Mae Wang district. Many people in Chom Thong district also felt the vibrations.
Mr Somboon Kosittanont, director of the Office of Environmental Geology of the Minteral Resources Department, said Wednesday that the latest tremor stemmed from the sliding of Mae Wang plate which is about 25 kilometres long.
The epicenter of the quake is in Tambon Mae Win, about 28 kilometres from Mae Wang district and 50 kilometres from Muang district of Chiang Mai.
Somboon said that the quake was minor and was unlikely to cause damages to buildings. However, he added that he office would kept monitoring Mae Wang plate movements.
