A strong earthquake struck Myanmar last evening, killing at least two people, including a child. The epicentre was close to the borders with Thailand and Laos and was just 10 kilometres deep. The quake struck 90 kilometres north of Chiang Rai in Thailand and 235 kilometres north-north-east of Chiang Mai, Thailand's second city and a popular tourist destination. Tremors spread as far away as Bangkok, almost 800 kilometres south of the epicentre, Hanoi and Myanmar's capital Naypyidaw. The quake was initially put at magnitude 7.0 by the the US Geological Survey, USGS, before being revised to 6.8. A powerful aftershock was later measured at magnitude 5.4 by the USGS.
