Strong moderately dangerous earthquake.
1,000 people will experience a very strong shaking and 33,000 people a strong shaking. The main reason for this high impact is the very shallow hypocenter. PNG is however well prepared for very strong to even massive earthquakes. Since 1000ths of years, the islands are regularly shuddered by massive earthquakes. The earthquake’s epicenter is below the rain forest where only primitive villages are located. These villages have NO brick or concrete houses which make them less vulnerable for destruction.
The main dangers during these earthquakes are landslides and mining accidents.
Emergency services will normally not react to this kind of earthquakes. Additionally, as they have no helicopters and as the hills are mostly saturated by clouds, they have to walk to the epicenter areas via normal walking trails. They often need many days to reach the epicenter area.
These are the facts of life at PNG. We would be very surprised if a report would ever be published on this earthquake by the PNG authorities or by the local PNG press.

Update :  nearest populated place to the epicenter is : Were Were (18km).
The closest civilian airport is Sim (18km).

Update :  Population close to the epicenter (source GDACS)
11 people are living within a radius of 2 km around the epicenter
150 people are living within a radius of 5 km
640 people are living within a radius of 10 km
3,752 people are living within a radius of 20 km
63,803 people are living within a radius of 50 km
301,887 people are living within a radius of 100 km
999,056 people are living within a radius of 200 km

Update : Landslides risk : The maximum slope in the area of the earthquake is 59.6% and the maximum altitude is 3605 m. Since this is a medium slope, the risk of earthquake induced landslides is medium. Note, however, that the slope data is not reliable on a local scale, while landslides depend very much on local topography, soil and meteorological conditions.

?
People :
Felt by persons at rest, on upper floors or favorably placed.
?
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.
?
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.
Structures :
Some large display windows cracked. A few earthenware toilet fixtures cracked.
?
People Felt by all. People and animals alarmed. Many run outside. Difficulty experienced in walking steadily.
Fittings :
Objects fall from shelves. Pictures fall from walls. Some furniture moved on smooth floors, some unsecured free-standing fireplaces moved. Glassware and crockery broken. Very unstable furniture overturned. Small church and school bells ring. Appliances move on bench or table tops. Filing cabinets or "easy glide" drawers may open (or shut).
Structures :
Slight damage to buildings with low standard. Some stucco or cement plaster falls. Large display windows broken. Damage to a few weak domestic chimneys, some may fall.
Environment :
Trees and bushes shake, or are heard to rustle. Loose material may be dislodged from sloping ground, e.g. existing slides, talus slopes, shingle slides.
?

?
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.
