6.9-magnitude earthquake hits off Papua New Guinea's Bougainville
AFP News | April 19, 2014
A strong 6.9-magnitude earthquake struck off Papua New Guinea’s Bougainville Island Saturday but there was no risk of a widespread tsunami, seismologists said.
The quake hit at 0104 GMT and was centred 62 kilometres southwest of the town of Panguna on Bougainville at a depth of 45 kilometres, the US Geological Survey said.
In its initial estimate, the USGS said there was a low likelihood of casualties and damage.
According to the Hawaii-based Pacific Tsunami Warning Center there was no threat of a destructive widespread tsunami based on historical data.
Geoscience Australia measured the quake at magnitude 7.0 and said it was probably felt within a wide radius, with the potential for localised shaking damage.
“Because it’s such a large event there’s a possibility of damage in that area,” seismologist Emma Mathews told AFP.
“But it’s nothing out of the ordinary for such an earthquake-prone country.”
Mathews said it was the latest in a recent cluster of earthquakes in the Panguna region, with five events recorded in the past week including powerful magnitude 7.6 and 7.5 tremors that triggered a local tsunami alert.
