2022 Papua New Guinea earthquake

On 11 September 2022, an earthquake of moment magnitude 7.6–7.7 struck Papua New Guinea, in the northern part of Morobe Province.

The normal faulting earthquake occurred with a hypocenter depth of 116.0 km (72.1 mi) beneath the Finisterre Range.

[5] The earthquake measured 7.6 on the W-phase moment magnitude (Mww ) scale at a depth of 116.0 km (72 mi) by the United States Geological Survey (USGS).

Deep-focus earthquakes, those with focal depths greater than 300 km, also occur beneath Papua New Guinea and the Bismarck Sea to the northeast.

[1] Prime Minister James Marape stated that the extent of destruction and casualties were unknown, and that multiple regions were impacted.

According to Kessy Sawang, a local politician, there was serious and a potential for more casualties in settlements around the Finisterre Range and along the coast.

The Morobe Provincial Disaster Director, Charley Masange, reported injuries from collapsed structures and debris.

[17] An aerial survey of Morobe province by Mission Aviation Fellowship revealed landslides but damage was limited.

[22] At the University of Goroka, a seven-storey dormitory building sustained large cracks and window awnings fell.

[27] The Ramu hydropower station at Kainantu was damaged, leading to a complete power outage across Madang and Morobe provinces.

[36][3] Fearing a tsunami, coastal inhabitants evacuated to higher ground after reporting a drop in sea level.

[11] Small airline companies and missionary groups helped airlift injured survivors out of jungle communities.

Prime Minister Marape instructed national and provincial disaster groups to survey the damage.

[37] The K92 mining company in Kainantu temporarily ceased operations to conduct an inspection of the site and ensure the safety of workers.

[39] Many survivors in the rural mountain communities were still waiting to be rescued by volunteers and private flight companies.

[40] DataCo PNG Ltd said that damage evaluation and restoration works were being made along its submarine cable system.

[41] District government officials of Madang and Morobe gathered to discuss plans in distributing relief efforts.

[42][43] Authorities in Kabwum said that they were unable to provide assistance because government buildings were destroyed during election violence.
