A new report is elevating the possibility that California could see an 8.0 or greater earthquake during the next 30 years.

The stat comes from the Third Uniform Earthquake Rupture Forecast, better known as UCERF3. The study was a collaboration by scientists from the U.S. Geological Survey, the Southern California Earthquake Center, the California Geological Survey and the California Earthquake Authority.

The group’s last report came out in 2008. While most of the findings were similar, the 2015 version raises the odds that California will see an 8.0 or higher tremor in the next three decades from 4.7% to about 7%. The scientists attribute the elevated risk to a better understanding of the relationship between different fault lines.

'Reawakened' faults could trigger big Okla. earthquakes

Though not the central point of this study, previous research has identified hydraulic fracturing, or fracking, as a likely cause of the more than 3,600 small earthquakes that rattled central Oklahoma from 2009 through 2014. Fracking is a method of extracting natural gas and oil from rock that lies deep underground.

Since late 2009, the rate of magnitude-3 or larger earthquakes in north-central Oklahoma has been nearly 300 times higher than in previous decades.

These reawakened faults in central Oklahoma could produce quakes as powerful as magnitude-5 and 6 earthquakes.

"Many faults are reactivating, with as many as 17 magnitude-4 earthquakes in 2014," McNamara said. In 2011, one even reached magnitude-5.4 in strength near Prague, Okla.

"When one looks closely enough at the recent plague of earthquakes, they are on faults, and shallow enough to be plausibly affected by fluid injection (from the fracking process)," Vidale said.

A major earthquake with a magnitude 7.7 struck off Papua New Guinea on Monday, official monitors said, and a tsunami warning was issued soon after.

The epicenter of the quake was near the town of Rabaul in the northeast of Papua New Guinea, The U.S. Geological Survey (USGS) said.

The Pacific Tsunami Warning Center in Hawaii said "hazardous tsunami waves are possible for coasts located within 1,000 km (620 miles) of the earthquake epicentre along the coasts of Papua New Guinea and the Solomon Islands". No destructive, Pacific-wide tsunami was expected, it said.
