Update 13:30 UTC: At least 10 houses were destroyed today

Update 11:21 UTC: More misery caused by today's aftershock
Well informed Radio New Zealand wrote earlier today (an excerpt) :
A significant aftershock in Papua New Guinea's Highlands has caused further devastation in Hela Province, according to reports emerging from the region.
The region has been struggling in the earthquake's aftermath, with aid slow to trickle in and tribal fighting seizing the provincial capital, Tari, forcing the military to take over the hospital after doctors fled.
Moses Komengi is a Tari resident who is currently in Port Moresby, he said his family phoned him to tell him of the latest devastation.
"I'm hearing that all our houses that were half damaged are all gone down and more destruction has happened," he said in a phone interview on Saturday night. "All my children they rang me that they cannot live more in our permanent house because all the houses are destroyed."
"I'm driving with my brother here, and he's from Korouba. He's hearing that one of his relatives - a young girl - has been crushed by the house," adding that he understood more people could have been killed in Tari.
The houses that weren't completely destroyed by February's earthquake had now been finished off, Mr Komengi said he was told by relatives, and the town, where the response had already been significantly hampered, had been taken back to square one.
"This will add on to the worst disaster and tribal fights and I don't know how people will cope with this," he said.
Mr Komengi said he had originally planned to return to Hela on Sunday, but was told the airport runway had been split in the middle.
"It's finished us off," he said.

Update 12:51 UTC:  Shaking map with possible related damage from the natural disaster specialists at CATnews (Risklayer - CEDIM), Karlsruhe, Germany. Map generated by Andreas Schäfer.

Update 06:45 UTC: Main earth movement based on the current focal mechanism.
People who experienced the shaking can easily determine which of both fault planes is the right one.
We believe that fault line 1 is the tright one in this case.

Update 06:31 UTC: Seismogram as recorded in a seismological station in Lorengau, Papua New Guinea. The earthquakes visible before the M6.2 are aftershocks of the M5.4 earthquake who happened 33 minutes earlier at New Britain

Update 06:30 UTC: The nearest locations are Hanoi (18km), Fugwa (25km), Egele (26km), Geroro (26km), Tangi (27km)

Update 06:29 UTC: The nearest airports are Koroba (32km), Suabi (34km), Pureni (38km), Mougulu (49km), Tari (50km)

Update 06:27 UTC: The fault line responsible for the mainshock and many powerful aftershocks is the New Guinea highlands fold and thrust belt

Update 06:22 UTC: GDACS expects less than 1000 people to have felt a very strong shaking and 6500 a strong shaking.

Update 06:14 UTC: USGS theoretical shaking map expects a strong to very strong shaking in the direct epicenter area

Update 06:08 UTC: Main risk in PNG highlands are landslides. The landslides were responsible for the more than 100 killed people during the mainshock and the very strong aftershock. A detailed number of fatalities was never given after the M7.5 earthquake from February 25. ER fears that there a lot more than the 160 killed people we could trace.

Update 06:08 UTC: Shaking rings of the epicenter area.

Update 06:05 UTC: Since a couple of weeks the aftershocks of the massive deadly earthquake were a lot weaker (M4 range). This new very strong one means that people should remain very alert for powerful new ones.

Update 05:59 UTC: Based on the present earthquake parameters (Magnitude, Depth, Population, etc) and our experience with earthquake damage impact, earthquake-report.com calls this earthquake extremely dangerous and expects injuries and serious damage

    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.
