SYDNEY, Australia (AFP) — Papua New Guinea sent troops and rescue workers after a powerful earthquake struck the Pacific nation’s mountainous interior Monday and damaged a gas plant and other buildings.
Authorities warned of aftershocks and landslides. There was no official information on fatalities or injuries in the rugged region but one unconfirmed report of deaths.
Assessment teams headed to affected areas near the 7.5-magnitude quake’s epicenter, which the US Geological Survey said was some 90 kilometers (55 miles) south of Porgera in Enga province.
“It is advisable to stay out of multi-storey buildings, to be aware of the potential of landslides, and to be prepared to move to open ground in the event that an aftershock is felt,” the chief secretary to the government, Isaac Lupari, said in a statement.
The tremor hit at a depth of 35 kilometers around 3:45 am (1745 GMT Sunday), US seismologists said, adding that there was no tsunami threat.
A 6.0-magnitude aftershock was recorded by the USGS at 4:26 pm nearby and another of magnitude 6.3 hit at 1.17 am early Tuesday.
The region is home to oil and gas production. ExxonMobil PNG said buildings at its Hides Gas Conditioning Plant were damaged but all its staff were “safe and accounted for”, with non-essential employees to be evacuated.
Australian resources company Oil Search said its operations in the area were being shut down as a precaution and for damage assessment, and there were no injuries reported among its staff so far.
Felix Taranu, a seismologist at the Geophysical Observatory in the capital Port Moresby, said social media posts reported blackouts and damage to buildings at Porgera, although he was not aware of any injuries.
He told AFP the quake was felt strongly at Mount Hagen, some 168 kilometers away from the epicenter.
“It will take some time to get assessment teams out there and get a clear picture of what’s happening,” he added.
The director of the Geohazards Management Division, Chris McKee, told AFP he had yet to receive any reports of damage although there was an unconfirmed report of fatalities.
“There’s an unconfirmed report of some deaths from Mendi (in the Southern Highlands), but I’m not exactly aware of where the fatalities occurred and this will have to be corroborated,” he said.
The quake’s epicenter was in rugged terrain 612 kilometers northwest of the capital Port Moresby.
USGS said earlier that some casualties and damage were possible and that recent earthquakes in the area had caused landslides.
It said homes in the region were “a mix of vulnerable and earthquake resistant construction”.
The impact should be relatively localized, it added.
Earthquakes are common in PNG, which sits on the so-called Pacific Ring of Fire, a hotspot for seismic activity due to friction between tectonic plates.
