IMPORTANT FINAL UPDATE 13/09 - 07:44 UTC : Good news from Wewak PNG.  The Stuart family living near Wewak in the Sepik river area reassured us that everything is OK over there : "We felt some strong shaking (10-15 seconds) in our building here in Wewak that has a concrete floor.  However, others here in Wewak didn't feel it at all.  I have not heard any news of damage anywhere".
Toni and Jason Stuart helped also with local reports on the August 1,2011 Bam (Biem) Island 6.8 magnitude earthquake.

Update : PNG has very few shaking deaths, even after sometimes violent earthquakes. Most of the victims in Papua New Guinea are due to tsunamis.

Update : 39,000 people will experience a strong shaking following the theoretical models from USGS. 174,000 people a moderate MMI V shaking and 340,000 people a light MMI IV shaking.

Update : It will take a number of hours before the coastal communities will hopefully report that everything is OK. Thanks to the close distance to Wewak, we will hopefully get some news this time.

Update : PNG houses are mostly build out of wood and have a very high resistance against earthquakes.

Update : The closest villages to the epicenter are : Wagamut, Kaup villages, Kaup and Samap.

Update : Wewak is the capital of the East Sepik province of Papua New Guinea.  It is the largest town between Madang and Jayapura.

Update : Australian Geoscience (instruments relatively close to PNG) has a magnitude of 6.3 but a far better depth of 62 km (much weaker shaking).

Update : So far we have NO sign of a tsunami warning or alert.  The danger would be only local as the magnitude is not strong enough to generate a wider tsunami.  GDACS has very good theoretical models and GDACS has not released a tsunami bulletin which is a very good sign.

Update : the earthquake occurred in the direct coastal area (only a few km from the coastline)
