A second powerful earthquake has hit Papua New Guinea in as many days, amid an increase in seismic activity along the fringes of the Pacific, known as the "Ring of Fire"
Tuesday's six-point-four magnitude tremor struck 142 kilometers southwest of the city of Mount Hagen at a depth of about 10 kilometers.
This led to a number of oil and gas operations to be closed due to damaged facilities, including that of energy giant ExxonMobil.
Meanwhile, a six-point-one-magnitude quake jolted waters just off eastern Indonesia.
It struck at a depth of about 12 kilometers in an area 44 kilometers off the coast of Airbuaya.
No tsunami warning was issued.
