Update 17:53 UTC: GDACS has no Tsunami report (Due to the depth and the limited Magnitude the probability of a tsunami is very limited)

Update 17:48 UTC: BMKG has called a tsunami warning for the Indonesian coast.

Update 17:38 UTC: The map below shows the tectonics of this area. Although made for a Sumatran earthquake, the picture is the same for this earthquake. At the same time the map shows why the depth of the earthquake is so deep. The Indo-Australian plate dives below the Eurasian plate and is locked in some areas. Due to the movement of the Indo-Australian plate, the stress increases gradually until its gets too big and breaks (earthquake). The movement of the plate is approx. 7 cm PER YEAR and is the reason that Indonesia has frequent massive earthquakes.

Update 17:16 UTC: Due to the depth and the elevated Magnitude the shaking will be felt in a very wide radius of 1000+ km

Screen Shot 2017-12-15 at 18.55.05

Update 17:14 UTC: USGS Shaking map gives a max. moderate shaking for a wide area (norm for deep earthquakes)

Update 17:10 UTC: USGS reports now a M6.5 Magnitude at a depth of 92 km BUT with an epicenter right below the coast

Screen Shot 2017-12-15 at 18.09.14

Update 17:03 UTC: Most shaking values we receive from Java are mentioning moderate to strong shaking but this can be very strong shaking nearer to the epicenter

Update 17:01 UTC: First indications did report M7.3 but later ones are now reporting M6.7


Update 17:00 UTC:  People along the Java coast can best auto-evacuate to higher ground

Update 16:57 UTC: Based on the present earthquake parameters (Magnitude, Depth, Population, etc) and our experience with earthquake damage impact, calls this earthquake extremely dangerous and expects injuries and serious damage

Some pre-1965 infill masonry panels damaged. A few post-1980 brick veneers damaged. Decayed timber piles of houses damaged. Houses not secured to foundations may move. Most unreinforced domestic chimneys damaged, some below roof-line, many brought down. Environment : Cracks appear on steep slopes and in wet ground. Small to moderate slides in roadside cuttings and unsupported excavations. Small water and sand ejections and localized lateral spreading adjacent to streams, canals, lakes, etc.
    MMI IX (Violent shaking) ?
    Structures Many low standard buildings destroyed. Ordinary workmanship buildings heavily damaged, some collapse. Reinforced masonry or concrete buildings damaged, some with partial collapse. Buildings and bridges designed and built to resist earthquakes damaged in some cases, some with flexible frames seriously damaged. Damage or permanent distortion to some buildings and bridges, designed and built to normal use standards. Houses not secured to foundations shifted off. Brick veneers fall and expose frames.
