Update 16:16 UTC: This is an small excerpt of an article in the always well informed Radio New Zealand. Bottom line: no damages yet or either No serious damages 🙂

"It was a very, very big earthquake. Every one of us had to run out of our houses, because it continued for some minutes. But everyone has stick to one place (in the open) because we don't want to move out, because we find we might get into some problems with landscapes and all this.

"So we are just waiting... because we are having small ones coming up."

Mr Togor said this morning's quake felt much bigger than Monday's 6.3 quake and subsequent aftershocks.

Meanwhile, the local MP, Elias Kapavore said from PNG's capital Port Moresby that he was contacting people in his district to try and establish the extent of damage or injury to people.

It was still too early to tell whether major damage had been sustained by infrastructure, the Pomio MP said.

Talking to RNZ Pacific on a mobile phone from Bago village in Pomio's Central Inland Local Level Government area, Alois Gonggi said the quake was felt strongly, although no great damage was done. He said local people were accustomed to quakes.

Update 22:56 UTC: If any damage was inflicted, we will report it immediately to our readers.

Update 22:55 UTC: TSUNAMI THREAT CANCELED

Update 22:29 UTC: The Tsunami threat remains as stated at 22:05 UTC

Update 22:27 UTC: USGS has decreased the Magnitude from M7.2 to M6.9 (a big difference). The depth has now been set to 35 km, in line with the mainshock and other very strong aftershocks.

Update 22:22 UTC: The strongest aftershocks so far : M5.1, M4.9 and M5.3

Update 22:17 UTC: These are the villages closest to the epicenter

Update 22:05 UTC: TSUNAMI UPDATE
Tsunami waves of 0.3 to 1 meter are possible along Papua New Guinea coasts.
Also expected are 0.3 meter tsunami waves along the coasts of the Solomon Islands

Update 22:02 UTC: Focal mechanism of this earthquake shows (like the mainshock and the other aftershocks), a thrust earthquake
Do beach balls looks like Chinese or Latin to you, check this article "Understanding Beach Balls"

Update 22:00 UTC: Shaking impact on the population and on the nearest cities

Update 21:57 UTC: 8,370 people have been exposed to a very strong MMI VII shaking

Update 21:54 UTC: The first tsunami threat message indicates tsunami danger in a radius of 300 km. We fear for possible tsunami waves on New Britain itself as the epicenter is almost on the coast.

Update 21:48 UTC: A Tsunami Threat has been called

Update 21:46 UTC: PNG people are somewhat used to massive earthquakes and damage is rare but this aftershock (it the Xth in a sequence) was massive and very shallow at the same time.

Update 21:37 UTC: Based on the present earthquake parameters (Magnitude, Depth, Population, etc) and our experience with earthquake damage impact, earthquake-report.com does expect at least some slight damage like cracks in walls, fallen tiles, etc.

    Shaking Strength *
    MMI II (Very weak shaking) ?
    People :
    Felt by persons at rest, on upper floors or favorably placed.
    MMI III (Weak shaking) ?
    People :
    Felt indoors; hanging objects may swing, vibration similar to passing of light trucks, duration may be estimated, may not be recognized as an earthquake.
    MMI IV (Light shaking) ?
    People :
    Generally noticed indoors but not outside. Light sleepers may be awakened. Vibration may be likened to the passing of heavy traffic, or to the jolt of a heavy object falling or striking the building.
    Fittings :
    Doors and windows rattle. Glassware and crockery rattle. Liquids in open vessels may be slightly disturbed. Standing motorcars may rock.
    Structures :
    Walls and frames of buildings, and partitions and suspended ceilings in commercial buildings, may be heard to creak.

    People :
    Generally felt outside, and by almost everyone indoors. Most sleepers awakened. A few people alarmed.
    Fittings :
    Small unstable objects are displaced or upset. Some glassware and crockery may be broken. Hanging pictures knock against the wall. Open doors may swing. Cupboard doors secured by magnetic catches may open. Pendulum clocks stop, start, or change rate.

Unrestrained water cylinders (hot-water cylinders) may move and leak. Some common windows cracked. Suspended ceilings damaged.
    Environment :
    Water made turbid by stirred up mud. Small slides such as falls of sand and gravel banks, and small rock-falls from steep slopes and cuttings. Instances of settlement of unconsolidated or wet, or weak soils. Some fine cracks appear in sloping ground. A few instances of liquefaction (i.e. small water and sand ejections).
    MMI VIII (Severe shaking) ?
    People Alarm may approach panic. Steering of motorcars greatly affected. Structures : Low standard buildings heavily damaged, some collapse. ordinary workmanship buildings damaged, some with partial collapse. Reinforced masonry or concrete buildings damaged in some cases. A few instances of damage to buildings and bridges designed and built to resist earthquakes. Monuments and pre-1976 elevated tanks and factory stacks twisted or brought down. 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. Environment : Cracking of ground conspicuous. Landsliding general on steep slopes. Liquefaction effects intensified and more widespread, with large lateral spreading and flow sliding adjacent to streams, canals, lakes, etc.
