Update 11:53 UTC : This earthquake was triggered by compression forces as can be seen in the mechanism below

Update 08:35 UTC : The least we can say is that the interaction in between the Indo-Australian plate and the Eurasian plate is very active at the moment. 3 strong to very strong earthquakes in a matter of 1 week and at different locations and different depths. What next ? Seismologists all over the world are trying to find patterns, clues who can at last a grain of hope in predicting the next strong one. But unfortunately … no generally accepted conclusive solution as far as we know.
Update 08:29 UTC : The lower map shows a 1916 M7.3 earthquake a little to the south. Interesting to notice that also that earthquake was at a depth of 100 km.
Update 08:14 UTC : The quake was felt for about 3 to 5 seconds on the nearby coast. At the time of writing this update only a couple of reports are mentioning some minor damage to a limited number of houses. There was never a risk for a tsunami.
Below the Geofon seismogram recorded at Jajag, Java. The big blue amplitude is this earthquake, the Red ones are the New Ireland and New Britain massive earthquakes who are visible on seismograms all over the world.

The strongest shaking was felt at the south-eastern part of Java. The earthquake itself was felt in Java, Bali and even Lombok. The main reason for the shaking is the depth of the hypocenter (breaking point inside the earth). If deeper, this weakens the shaking but at the same time increases the radius where the quake was felt.
