No general Tsunami risk (local smaller tsunamis are always possible).
GDACS issued a GREEN earthquake report (see details below)
NO people live in an area of 25 km around the epicenter.
27,800 people live in an area of 50 km around the epicenter.
110,000 people live in an area of 100 km around the epicenter.
We have enclosed the seismogram of this earthquake to give you an idea of the travel time of the wave in the earth. We monitor tens of stations all around the globe and the Chiang Mai, Thailand station was the closest we could find. The signal arrived in Chiang Mai roughly 4 minutes after the earthquake struck and traveled a distance of 1850 km.
The magnitude of the Papua New Guinea quake was 6.4, a lot stronger, but because of the greater distance, the markings on the seismogram in Chiang Mai are smaller.

Update 12:55 UTC :  Simeulue residents could feel the earthquake at between II and III MMI (Modified Mercalli Intensity (= Weak shaking (ER))
Local residents rushed out of their houses when they felt the temblor. “They did not panic, but they are still traumatized because of the previous earthquakes, so they rushed out of the houses when the earthquake occurred”
