7.1 Earthquake Strikes Papua New Guinea

A very strong mag 7.1 earthquake hit the mainland of Papua New Guinea about 13.5m SE of the Koranga geothermal area where a lot of illegal gold mining occurs. The Koranga geothermal area has not had any magmatic eruption, rather it has had either a man made explosion int he past, or this was a hydrothermal eruption. In any case, the quake will likely destabilize the area, and this puts illegal gold miners at risk.

The quake occurred at a depth of around 75 miles, and was not expected to generate a tsunami based on its location.

The quake due to its depth is not expected to destabilize any other volcanic areas in the country, although this is always a possibility. Papua New Guinea lies on the Pacific Ring of Fire, and is prone to volcanic eruptions, and large earthquakes.
